In this tutorial, we'll be playing around with curves and procedural objects a bit.

Starting off with only a handfull of shapes, we will make an animation of a ride through an abandoned mine. The technique used will allow you to make changes to the shape of the path easily and not have to worry about recreating stuff like the motion from scratch.

Also, I will try to include some relaxing statements here so after reading, Ton will be ready for work again! ;-)

Hit it!

In the side view, add a Bezier curve. Go to the EditButtons screen, and select the button '3D'. This will allow you to move the vertices 'out of the plane', or make the curve truly 3 dimensional.

With the curve in editmode (TAB KEY- the vertices should be visible), add some points to the curve with CTRL-LeftMouse. When finished, you should have something like this:

Now, we'll attach the camera to the path. First, select the camera. Hold the shift button and select the path. Make the path the parent of the camera with CTRL-P.Next, select the path and go to the AnimButtons screen. Now, when you select the CurvePath button, the camera will move along the path. (Animate with ALT-A).Note:Depending on how your curve has been drawn, the camera can be displaced when you select CurvePath. Just drag it back in place - that should do the trick.This is nice, but not enough - we want the camera to look in the right direction, too! Fortunately, there's a button for this, too: CurveFollow. (Make sure the cam's up vector points the right way!)Note:For some reason, the camera will rotate 90 degrees when you select this button. As in the note above, just correct this motion and you should be fine.

Creating the rails

The rails will be creating by applying a bevel object to the path. In front view, add another curve and create the shape for a rail - something like this:

Hint: you can close a curve by pressing [C] while in editmode.Scale the shape down, and duplicate it. Join the curves together by selecting them both, and pressing CTRL-J.In the bottom-right of the screen, you can read the object's name. It's probably something like OB:Curve.001 (it is for me, anyway). Now select the main path, go to the EditButtons screen and enter the object name you just found in the BevObj: field.


If all goes well, you're now looking at some cool rails. Chances are, though, that the rails are 90 degrees rotates relative to the rails shapes you just drew:

To correct this, select the rails shapes, enter edit mode, select all vertice (AKEY), and rotate them 90 degrees (RKEY, next hold down CTRL while dragging the mouse. CTRL will restrict the rotation angles to multiples of 5 degrees).By now, we should all be happy campers and have a model like this:

Procedural Objects

Now, the fun part starts. We'll use procedural objects to create some of the woodwork you find in mines. We'll start off with the ties; these are the wooden blocks that connect the rails.
Start off by creating a block, a bit wider than the two rails.

Make the rails the parent of the block. (Select the block, hold down the shift key and select the rails. Select CTRL-P). Now, when you animate, you'll notice the block is following the rails, too. Select the block, and go to the animButtons screen. Select the button called 'DupliFrames'. This option will create a 'virtual copy' of the block for each frame of the animation.There are a bit too many copies right now. Increase the value of 'DupOff' until your rails looks good to you. (I used a value of 2).
Now, create a shape like this:
and give it some depth (set the extrude parameter if you used a curve, or use the extrude command when you've created a mesh). Again, place the shape on the beginning of the rails, make the rails the parent of this shape, and set DupliFrames. Fiddle around with the DupOff value untill you're satisfied.
For lighting, create a spotlight, place it just above the camera and parent it to the camera. (Make sure it points forward ;-). This will simulate a light being mounted on your mine cart. However, because the lamp's direction will follow your viewing direction exactly, the lighting will look too artificial.Create an empty, and place it a bit in front of the camera. Parent it to the rails. Select the lamp (first!) and then the empty. Select CTRL-T (Make Track) to make the light follow the empty. When you do this, the direction of the spotlight will probably be screwed up again. Correct this by rotating the light untill it points to the empty.Select the empty, go to the AnimButtons screen and set TimeOffset to a small negative value (like -3). This will cause the empty to run 'ahead of the light' (in time).The direction of the light is now uncoupled from that of the camera and the resulting lighting will look much better.
Finally, I've created a rock wall by making another extrusion along the path. Each path can only have ony bevel object however, so you need to duplicate the rails path first (use shift-D, NOT alt-D!), create a rock wall outline and extrude it.
Finally, after adding some decent textures and lighting, here's the result:


  1. Hi,

    i found this tut very useful

    thanx alot !

    PS can you move a point in a NURBS curve in thru the z-axis ?

    whenever i try, the point moves in x and y but not the z

  2. Hi Ashwar,

    NURBS curves are 2D by default. You can switch them to 3D though in the EditButtons Window (F9). In the 'Curves and Surfaces' tab, select '3D'. Alternatively, you can use Bezier curves.


  3. HI White Knight, I just checked in Blender 2.40 and it still works ok. Just be sure that you have the curve selected and then switch to the Edit Buttons (F9). The option CurveFollow should be there and it should work fine. If it doesn't, please email the file to me and I'll take a look. (Contact me with the contact form at the top of the page first to get my email address).


  4. Hi,

    Your tutorials are really great but I had a problem with this one:
    I can't add a point to the curve at the beginning. Ctrl left click simply doesn't work. I'm in editmode, I can see the vertices but I can't add any points.
    Please help me!

  5. What's a Bevel object? Here at Morgan High School we've discovered a "Bevel" option in the "Specials" menu, but it, in no way, works towards the goal of this tutorial. I have one curve, and I shaped a cube to the shape of a rail segment, but now I don't know what's going on.

  6. Hi Jacob,

    I've added some extra information above. For starters, be sure that you create the outline of the rails from a curve, not from a mesh.



  7. i might have done something wrong but when i type in Curve.001 the curve has the shape of the rail i made but its a jummbled mess,nothing like what i made.at parts of the track it it gets all scrunchy, black and crummpled.am i doing something wrong?

  8. You guys having trouble with CTRL-LftClick to add vertices, in order to add vertices that way you have to have only one vert selected, and it must be an end vert.

    If you have none selected, or if you have a vert that is in-between two other verts, nothing will happen, or if you have an end vert and another selected, nothing.

    ONE end vert only.

  9. newbie: I had exactly the same trouble with my rails. Turns out, if I typed in Curve.001 as the bevel object whilst my path was in Object mode the rails went all scrunchy as you observe. I found that if my path was in Edit mode when I typed in the Curve.001 bit, it all worked fine.

  10. An empty is an object that can be used to manipulate other things. It can be positioned, scaled or animated just like any other object, but it is entirely invisible in the final render. It can be used to track cameras, scale or orient textures, or alter just about any feature which can map to another object. You`ll find it in the root of the "Add" menu.

  11. Hey, i cannot find the ‘DupliFrames’ option. Where is it? (i have downloaded the latest version of blender)

  12. Wasup everybody,

    I dont know why but I am not very good at this. I have the 2.4 version and I still cant figure out how to make the rails/ I mean I cant do the first step of the Tut. I dont know if somebody can help even more, I steps are very good and what not but I need a little more help. If anybody can help Thanks alot I would like to done some nice things to the Caves and all that.

  13. Nice tut! I am in the process of creating a rollercoaster. I knew how to do everything but make the ties. OK now to my problems. I believe that both problems are related. First problem, the camera goes way to fast. Second problem, the rails are to far apart! HELP ME!

  14. I have a problem.... I've made the rails and the tie (and i made a parent to follow the rail). It will follow the rail in the animation but in your picture, you have all the ties at once. What's my problem?

  15. Well, as usual I am having my troubles! I have gotten to the step where it is time to "BevOb" the rails onto the curve. Now when I do this, I get something kind of funny. Firstly, the track I have created is all black, yet no material is applied. Secondly, it is sort of twisted up at the ends, and there's little mutations and stuff on it. Now I noticed that both Newbie and Richard appear to have experienced a similar issue. Richard offered a solution--apply the BevOp in edit mode rather than object mode. However, I have tried this operation in both of the two modes, and each in turn produced identically problematic rails. So now I am lost. Would it help if I emailed you the .blend file B@rt? If so, at what step should the file be when I send it?


  16. Ok... well I realized the problem was the dupliframes. I turned that on but I'm having the problem of the objects following the path not being positioned correctly. Ties are sometimes too far below the rail and sometimes the cave-brace things are IN the rail. What can I do to fix this?

  17. B@rt,

    Thanks for this fun and useful tutorial. I found it pretty straight forward after going through all the preceeding ones. Figuring out which views to use while editing the rail curve was a good exercise too. I had to redo the curve a couple times before I got it looking good. I don't understand the relationship between the length of the intial curve and the number of frames it takes to traverse it yet, but I'll figure it out eventually.


  18. Jonnyappleseed on

    If you are femilare with the IPO editor, you can fix the problem by extending the length of the curve in the ipo window.

  19. laughing cheese on

    Hi there!

    These are great tutorials, but I'm having trouble making them work with 2.41! (Sorry, you probably get that a lot...)

    You start out by saying "in the side view". Which view is the side view in? And Blender never starts in two windows :confused:

  20. @laughing cheese: press NUMPAD+3 (with numlock turned on) to switch the 3d view to sideview. Press NUMPAD+4 for top viev, NUMPAD+1 for front view

  21. ok im a noob at this stuff and i dont no what every thing means right now.. im stuck where it says.. animbuttons, and the curve path button... where are these at and what do they look like?

  22. ok so far i only got to the animation part... when i tried to put that /_\ thingy onto the rails it never works.. all i get is to rods... what am i doing wrong???

  23. Thord Johansson on

    Help! Can I download this somewhere? Someone who is finished and would like to send the finished file to me, in some kind of exported format that I can show without Blender???? I have Blender, but that shouldn't be necessary should it?

  24. heyy everybody~

    nice tutorials, but i wonder how can u make two windows (*first pic) , coz i can nv manage to do it...i asked my fds, but they cudnt figure it out too~ XPP
    and seriously~ blender is not my stuff, lol....so mani buttons!! (*scream)

  25. Thord Johansson on

    I'm kinda serious here.
    Help! Can I download this somewhere? Someone who is finished and would like to send the finished file to me, in some kind of exported format that I can show without Blender???? I have Blender, but that shouldn’t be necessary should it?

  26. @Thord: the whole point of the tutorial is that you have to do it yourself :) Go ahead, it won't take you more than a few hours.

  27. Hello

    It was a great tutorial and I had a lot of fun.
    but I had one setback (almost every tutorial bears one)- in render mode the rails (the path) did not appear!! why?? why?!! wwwwwwwhy????!!!!!

  28. Antipeopleperson on

    Ok a great tutorial.... i got everything done and it wasn't to hard. But i want to extend on to the mine to make it alot longer and a bit more fun that just a few twists and what not. So is there a way to add on to it with out making a whole new mine?

  29. im just a beginner using blender and while i was creating my own picture after the picture got bigger and bigger i wasn't able to slelect some of the parts of the picture anymore and after a while they dissapeared. Wow im really stumped on this and i can't figure out why, my guess is that the picture is just getting too big i guess but like i said im a noob to this and i would appreciate any feedback please.

  30. @my Name: In the edit menu there's a tiny gray field where it says "path length" Normally there should be set a value of 100. If You increase this value, the camera will slow down eventually.

    As for myself, i have the same problem as dnx and Danny K. The rails won't show in the final render. Any ideas?

  31. Happy Blending on

    Oh my GOD! Thank You!

    You got the solution for my problem!
    Im working on a rollercoaster... The Mesh is ready and UV-Skinned
    (cause it's gonna be a special 1 with Jet Engine and Afterburner LOL, should be fun to ride with...)

    But the point was that i actually didn't know, how to create those damn Coaster-Tracks!
    I've been searching for a long time now... ...and this WORKS !!!!!

    Best Regards

  32. Hey, This looks awsome so far, but one problem, after making the first rail part, and creating its other-side-counterpart, joining them, and renaming it as "Rail" I select the pat, and put in "Rail" on the BevOb: but nothing changes.... I tried this without the name changed, in edit mode, in object mode, and even joining both the rails in edit mode instead of object mode. What have I done wrong?

  33. I have a nice rails with all the woodwork, but when I animate it, the rail ties and the other thing still move along with the camera. What am I doing wrong?

  34. I was wondering if there was a way to change the number of frames it takes for the camera to track its way around the line. 'Cause I wanted to make a large scale one, and 100 frames is just a little too quick. And cutting the frames/second just kills it.
    Any help?

  35. Hi :)

    Very useful tutorial but i've got into a problem.. I'm making a rollercoaster, and what is a rollercoaster without a loop ? :P So i've made a loop on my path, but when my camera is going at the loop it's going on the outerside of the loop, not staying inside as i want it to.. Is there any solution to this problem?

  36. SnakesonaPlane! on

    Hey... thanks for this tuorial! As all the others here, I have a problem. I've been going through the tutorial and when I get to making the ties(/the "Dupliframes" part) it doesn't work... I'm in the "Anim settings" window and I pressed down the "Dupliframes" tab, but nothing happened. I think my problem is that I'm not using a "procedural object". I only think that because I don't exactly know what they are. All I know is that it's not a "Mesh", a "Lattice", or a "Curve". (At least they don't work like the tutorial said they should. I think I'm using Blender 2.37, but I'm not really sure how to find the version number... Anyway, if someone could help me with that, I'd be very appreciative. Thanks.

  37. @SnakesonaPlane: Did you make the rails parent of the ties?

    I still have the same problem as above. Do I have to make the original tie invisible or something like that? I could upload the .blend file on my webspace if someone wants to see it. Please help.

  38. SnakesonaPlane! on

    @Anna, I did make the rails the parent of the ties. (selected the rails, held "Shift" and selected the rails, pressed "ctrl p" selected the option of "Follow path" set to "curve follow", and then pressed "DupliFrames"- nothing happened...) thanks for the effort though! You know, it actually looks as though we have the same problem ( I may be wrong)..

  39. No, DupliFrames works fine here. I think I used the 'Normal Parent' option, maybe that will work for you too.

    My problem is that the original tie still follows the path, although DupliFrames also works. I'll make a screenshot.

    (Seems like I can't place a link here... let's try this. Just type www. in front of it.)


    The red arrow points to the thing that follows the path. The rest is DupliFrames stuff.

  40. No, DupliFrames works fine here. I think I used the 'Normal Parent' option, maybe that will work for you too.

    My problem is that the original tie still follows the path, although DupliFrames also works. I'll make a screenshot.

    (It doesn't seem to work to post an URL here... Maybe this works. Change the -'s into .'s)

    The red arrow points to the thing that follows the path. The rest is DupliFrames stuff.

  41. I cant figure this tutorial out. Ive tried it many times and run into the same problem each time; the BevOb. B@rt, could you please try going through the tutorial in the new version of Blender? This and the other tutorials are (sadly) becoming hopeleslly out of date :-(. Amazing how fast Blender keeps changing, but its confusing for us out here! Thanks for your time ;-)


  42. Ok, so I got up to the part where you make the sahpe for the rail, but im not exactly sure how to go about making the curve into the actual rail. Thanks to anyone that helps.

  43. I'm hoping it's not just me, but I had a heck of a time finding the dupliframs button, or the animbutton. Took me like an hour of searching on google before I figure out that you press F7 to get to the screen. I was assuming it was under F10, and had maybe been removed from Blender 2.42 and replaced with Sequence Arrays or some such. Hopefully that helps someone other then me.


  44. SnakesonaPlane! on

    I just figured it out! Thanks a bunch, Anna! Because my thanks comes in bunches... just like bananas... And you think I'm joking.

  45. GREat! i even made another animation it took a bezier curve and i just made it a circle and i typed in curve and used "follow path"and Alt+A and whoa it was awsome just the cube part of Dumpli frames part!

  46. Hi,
    I don't understand what you mean with 'join the curves' at the rails. So I tried to extrude the cuve and then make it follow with dupliframes. But it didn't work.....

  47. anonymous, i am having issues with the ties i know where both animation buttons are but when i click on them it is the same and there are no "drop off" buttons why HELP!

  48. @snakesonaplane or ne1 who knows how, please tell me how to use dupliframes.wenever i try to use it, the button goes down, but nothing happens to the ties.

  49. This a very intersting tutorial. Thanks.
    I want to control the speed of the camera along the path. I read that this have to be done from the IPO window. But after many try I haven't been able to edit anything in that window. I think there is a black line at speed 1.0 with rails selected and path in the IPO header choise but I can't select the line.

    I'm lokking for help on this, thanks.

  50. I'm about to go insane.....

    Everything looks fine in the 3d windows, but when I render it out the rails aren't visible!

    Someone PLEASE help me with this.

  51. ok im just having trubble getting 3d meshes to curve. like i hava a tube and its gunna be a power wire to a computer but i cant figure out how to use the curvs to get the tube to curve. can you help out a noob...........................please.

  52. Bits of Advice.

    I noticed I had to give my rails a material to get them to show up. Try that if they're being invisible on you. As for the dupliframes part, make sure your track is un-selected. I found having the track + something else selected when hitting dupliframes doesn't do anything to the other object, so make sure you deselect everything, and only pick the one object you want dupliframes enabled for.

    jonathan, I've seen a few awesome tutorials on wires, one even did the curvy telephone wire, and was awesome. Do some google searching and good luck ;)

  53. Another great tutorial - I got caught out by the dupliframes on the rails and rocks making them disappear too, so thanks for the comments. Looking forward to extending the ride and maybe adding some skeletons...

    Does anyone know how to select the duplicated objects ie. the beams and sleepers in the 3d views? I keep having to flick over to the Scene Outliner and choose them from the tree there, as I can't right-click on the original or the dups (Blender 2.32).

  54. This was a great tutorial, it's always fun to learn something new about blender. been using it for years and didn't know about any of this stuff. thank b@rt.

    @lazykate - you can selected the duplicated objects by right clicking on the copy at the end of the path

    @josh - to get the camera to animate, go to the first frame of the path and insert a loc keyframe (select the camera and press the I-key), and then do the same on the last frame of the path.

  55. Is there any way to use bullet physics to make the camera/other object go on the track with gravity/friction, rather than just slide along at a predefined speed? (if so I will make some kind of game with this.)

  56. i cant figure out wy my beizer curve doesnt have verticies.... and i cant add any. i can go to 3d mode, and it still doesnt do anything. it just has things on the end of the curve that allow you to bend it. help?

  57. Looks like a great Tutorial. However I can't get to the end as I hit a problem.
    I am trying this tutorial with the latest build of Blender (2.44) and whenever I try to create the rails, by putting the Curve.001 into the Bevob of the path - the rails just come out as a mess and bear no relation to the path.

    Can anyone help, I have tried several things - including doing the relevant step in both Object and Edit mode and the same thing happens. I can't seem to find a way to fix it!

    All help really appreciated, I would really like to get a grasp on this, but it is proving almost impossible at the moment.



  58. Trickey,

    I had the same problem with the cave walls. I found that the problem was that I was creating the cave walls with a 3D curve instead of a 2d curve. So I started over with the cave walls, did a 2D bezier in view 7 and it worked great. I found it helped immensely to have two views open. 7 in one view and 0 in the other, that way I could manipulate the cave wall in the 7 view and see the results in view 0. Also, keep in mind the orientation of the initial rail or cave walls to the path is not important. It will align itself when you do the DupeFrames.

    Here's my problem. My supports are hollow. Can anybody tell me how to select the ties or the supports after they have been "dupeFramed"? I can't seem to select them in either Object or Edit mode. Or, how can I put faces on them? They have sides but no faces.

  59. GrandDukeAdense on

    I don't get it to work at all :P :P :P well, i'm a hopeless modeler when doing stuff like this. hehe

  60. Hi!
    I read this tutorial, and I get succes to makeing this. This tutorial so helpful for me,

  61. Thanks alot for this tutorial. It works in modeling but it doesnt in the game engine. Is there any way of using this in a game???

  62. OMG this tuttorial was one of the most usefull i have ever done! It really helped me to leaarn the basics of the animating and how powerfull curve tool could be! Thx alot!

  63. This is too hard!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

  64. Hi Bart,

    I can't manage to make the cave's "walls" or whatever you call it. What shall I use to make it? A curve or maybe a mesh? And can I somehow just make a little bit of the wall and then parent it to the rails? So I don't have to make every bit of the wall, around the rails.

    And thank you for taking time to help all us who cant do it by ourself.

  65. hey i just downloaded blender a day or two ago so i realy have no cloo what im doing. but my real problem is i cant get the track to go down hill \

  66. ..........**..........


  67. Looks like an interesting tut but I have come to a stopping point. When attempting to make the rails; I make the first bezier curve, duplicate it...and then when I join the two curves, nothing happens. Is this correct? I'm expecting to see the two curves visually connected, but I am probably mistaken. Any suggestions?

  68. Thanks for a great tutorial! Easy to follow.
    A tip for others. Align, camera, rails and ties with the curve at the starting point before making the curve parent.

  69. 1. copy and join the railcurves
    -> /'\ *copy* => /'\ /'\
    When you copy in object mode you have 2 objects, join them into ONE object. When you do both of them in editmode, they already one object.

    2. Making your tunnel
    -> copy your very first bezircurve (now your railway) and delete the BevOb (F9) => you see the curve between your railway, now do same how you did your railway with the copied curve (make a shape with bezir-curves and put its name into BevObj of the copied curve)

    3. Don't forget to play around with the centers of your objects and realign them!!

    I hope this helps to overcome some stops i had myself, and never give up ;)

  70. I made the rails which do look little diffrent...
    But when i try to add them I am completly clueless... If i go to the rails and go to the BevOb there's nothing there... I do know the name is cruve.004
    And if i enter that in the BevOb of the rail Nothing happens
    Please please please!! help me!

  71. Thanks for creating this tutorial, I have found it very useful - although it took me a couple of attempts to get it correct (all part of the learning process).

    I have a slightly off-topic question about texturing the procedural objects.
    Using procedural textures, I either get a texture which tracks with the animation and appears to move over the objects or a texture which is fixed to the scene and thus looks different on objects which are rotated relative to each other. In the example at the end of the tutorial, the textures appear to be correctly mapped.

    Please could someone suggest a way to achieve this? I have seen other tutorials suggest converting the procedural objects with 'make real' as a possibility. Is this the best solution, or is there a better way? Would UV mapping work?

  72. i cant do anything because yall are using a different blender than me. i am using the newest one and noting works... HELP!!!

  73. Solved it! ORCO mapping (which I started with) works as expected. The problem was that my textures had too many fine, high contrast lines in them. This caused interference patterns which appeared to move with the camera.


    Which version? Works alright for me with 2.45 (which is the current released version). Some of the panels arranged in a slightly different way, but no major differences.

  74. I typed Curve.001 into BevOb: but the rails came out mucked up and kept turning sharply back on themselves

    What have I done wrong!!!

  75. i must be using a different blender...please help!!
    I dont have half the options hes talking about (atleast, not in the menus he says they're at...)

  76. Great tutoral
    how ever I see a problem
    if you make a rail line with more then a 90 degree turn in it. When you duplicate it the 2 paths will run together.
    Even in your screen shots you can see that the 2 rail lines get closer together. This one is particularly good example. http://www.blendernation.com/wp-content/xoom/tutorials/mineRide/Mine6.jpg Rail cars can't have the 2 lines become closer together or farther apart, they will pop off. In order to make a turn and ceep the rail lines equall distance, the curve in the one rail needs the same center as the curve in the other rail. its geomitry.
    My blender skills are not high enuf to do this easly. :( or i would explane how.
    I find your tutoral very usefull and i refure to it quite often. So dont get ridof it or any thing. :)

  77. Hi!
    I'm a Fine Arts Student, and my prof requires us to use Blender in our plates. Currently, we're doing an animated electric fan. Can't figure it out, man. Geez.. I'm failing the subject. ;c Hope this tutorial will help. We'll find out soon, but not now. Haha ü

  78. Ummm... woulden't making the rails with a cube be better? 'cause i can't seem to make the rails with just the curve...

  79. How do you slow down the speed(it seems that its just able to make it in 100 frames)? i did just make the framerate 12 to slow down and how do you make the camera move slower when it goes uppward and faster when it goes downwards?

  80. insomniac, just model the fan, change to animation mode and hi-light the fan and press i and chose LocRot then set the current frame of animation number to 15 or such (above your buttons pannel) turn your fan in the dirrection you want it to turn by 90 degrees (or until your fan looks the same as it was before rotation it) and press i and chose LocRot agian and in the Ipo curve editor window (to your right by default) and select the line (right click you wont notice anything except that a Rot to your right has high-lighted) that has just appeared going up or down on the chart and click the Curve menu go to Extend Mode and click Extrapolation and then when you press play your fan should turn continuosly

    Or If Your Fan Is In The Game Engine
    model the fan, change to animation mode and hi-light it and go into the logic pannel, add a sensor and set on always (will turn non-stop) or set keyboard and chose a key (which when pressed will turn your fan only when your running the game engine, must be in object mode and press P to get into), add a controller and actuater, join them all together by clicking and dragging from the little circle next to them (2 joins, del to get rid of the connections when mouse is over them the connection will turn white) and on the actuater area set one of the 3 choises next to dRot to 1 or -1 if it's turning backwards (or whatever speed you want it to turn) (if its turning on the wrong axis just set the 1 or -1 to a differant spot under dRot and reset the previous 1 or -1 to 0 again or it will turn on two axis at the same time) and click off L at the end of the row to remove local rotation wich can muck up the rotation.

    I think this is right?

    [Mutchumektron] this guide sucks!

    Yeah but in a good way!

    If you have a specific problem, ask and someone can probably help. If you're new to Blender, it can be difficult to learn (even the button changes between versions, since there are so many buttons), but time spent is well worth it. If you just like telling people what sucks, none of us can help you with that problem.

    Well happy birthday to me (I'm 36,000,002) - learned something useful. One glitch with the original tie following along (the rest of the ties are fine) - I'll keep at it though.

    Peace etc.

    Great Tutorial!! I had a few issues with jumbled up rails (same as alot of the other comments)
    But by experimenting a bit i figured it out.

    The bezier curves are a great addition to blender, and it looks as if alot can be done with them with the right knowledge! :)

  83. Spunkycomics on

    Oh, and as to the people having problems with dupliframes, i had the same thing. Make sure that you only have the tie selected when enabling dupliframes.

  84. Great tutorial! Is there any way to vary the speed throughout the ride? I was thinking of making a roller coaster animation, and I think it would be A LOT more fun if the camera sped up for the hills...

  85. I like the tutorial, but i have been having a lot of difficulties with it. How do you create sharp
    corners with a curve? i get completely confused once it comes to creating the rails.

  86. lalaboy; To curve a line, add the bezier curve and right click on one of the endpoints. on each end of the curve there should be lines with three different points that you can click on to manipulate the curve in different ways.
    To add more vertices click on an endpoint and then hold ctrl and click where you want the next vertex to be.

  87. Ok i did everything up until the bevel thingy i don't know how to make the box around that shap that you made us make

  88. great tutorial. it taught me lots of things as I'm a complete noob.
    anyways. I decided to add cart and a lamp hanging on stick in he cart to make it look more realistic.
    what I don't understand is ho do u get rid of the block between the rails that keep following the path? I mean got dupli frames right but I can't get rid of the original and it keeps following the cart. I use blender 2.5

  89. I'm using blender 2.46 and I am having trouble adding the bezier curve and how do you make the screen split like in the beginning?

  90. Great job! I love the tutorial. I'm continuing to make my track longer, which I'm not having any problems with. But, is there a way I can make the camera move slower? The camera moves really fast and it makes it hard to watch the final video.

  91. Hey! I can't figure out how to create the walls . Do I just create a section of the tunnel and dupliframe it? Can someone help me?

    Thanks a lot!

    **great tutorial, by the way! keep it up!

  92. @Blake:

    there's a way to slow the camera down by going into the edit mode of your Path. You increase the Path lenght (Pathlen). It increase the numbers of frames required to go trough your path.

    hey, can anyone tell me how to import more than one object in blender 2.47, cause when i import something it just replaces the other one PZZZ

  94. Has anyone figured out the problem where the first rail tie follows the camera? Please post the solution if you know how to fix this. Thanks!

  95. The BevOb is blank and when I type in curve.001 I get an error that says cant bevel/taper own object. How do I turn the Rail curves into the rails on this version? Can someone help me? Didnt see an answer in any of the forum above.

  96. Cheers! thanks a lot its a really really old tutorial but still great :D! even though took some ages figuring out how to do stuff in v4.8 :P but still i learned a lot!!^^

  97. there are like 999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999999 comments here! cosh!

  98. @Flexo: the best solution is simply to move the camera a little ahead of the board, so when it moves, the movement is off camera. To everyone else, the majority of your problems have already been adressed, all you have to do is look through the comments, and you'll find a solution.

  99. Do you think you can go a little bit more into detail on how you created the rock wall? I'm using Blender 2.48a and I had to find just about every control on my own from scratch to this point and and I have no idea how to do what you are asking when it comes to this wall. Up to this point, my project is kick a$$ but I'm not sure how to do this and I'm not ready to give up! Please help. Thanks

  100. Sry for being such a noob but do you think you could post an updated version with some more pics, it would be soo much easier :P

  101. okay i figured out the bevOb thing with the rail shape curve but i dont get where to join the duplicated object and when i put in Curve.001 in the BevOb field the track is WAAAAYYY scewed up. Could someone please be more specific on this part? why am i the one of the few who dont get this?

  102. Thanks for great tutorial!

    I have same problem as Anna (from 2006 posting):

    "original tie still follows the path, although DupliFrames also works"

    I set DupOff to 2, and get good spacing for my ties. But, the original tie still follows along the path in between the other ties (i.e., it doesn't get offset like the stationary ones). Is there a way to turn off the original ties and only render the "duplicated" ones?

    Thanks for any help!

  103. To Matt M:
    Not that <> know of. just adjust the camera angle and position so the original rail tie and shaft support are not inside the black rectangle on the screen in view NumPad0.

  104. im having a problem with the rail i know how to make the rail but when i look in the bevob field thar is int a name and when i tiyp it in curve 001 and push enter it gos blank can you help

  105. im having a problem with the rail i know how to make the rail but when i look in the bevob field thar is int a name and when i tiyp it in curve 001 and push enter it gos blank can you help thanks

  106. well i can help a little i just watch this tutorial long time ago like 2006, i recently made something with the same dupliverts on the object parent to the curve technique.
    try to see decrease the path leng to a number that ajust to your needs, and in the dupliverts menu try to not use if not working right.

  107. so I followed the tutorial in blender 2.49, i managed to get around the differences, but when i animate, the wood stuff follows the path even though it has doubles showing. What do i do?

  108. quand u ont pour relier les deux pièces de matériel ferroviaire ainsi que, CTRL-J ne fonctionne pas. des idées?

  109. Ont u quand pour Relier les deux pièces de matériel ferroviaire ainsi q, CTRL-j sa ne fonctionne pas Des idées? merçi

  110. Great tutorial,

    however i get up to stage where you create the rails and i cannot get beyond that. I make the rail profile, fine duplicate ,fine and I think that I can join them together but it does'nt give feedback so you assume.

    When you say that there should be a name that pops up in BevOb, (like Curve,001 ) sorry i get nothing. I try typing something in and press return , it just erases....I cannot get bev ob to do anything! also what is the edit buttons screen I push F9 like asked and gets me nowhere. I really want to get somewhere with this tutorial but feel like this section needs to be clarified...


    i am using Blender 2.44.

  111. Ummm for some reason my textures come out funny. Like all the join have black lines around them and everything apart fromt he very top of the track is really really dark even when i move the lamp down further
