Hi guys! A couple of weeks ago I started working on BlenRig 3.o again, and now I´m releasing the first Alpha version.

One of the main features of BlenRig 3.0 is it´s muscle simulation system based on Shrinkwrap. Check it out on my site, there are some pictures there, a short testing video and more info. The rig is available at the downloads section.

I have a LONG history with Blender - I wrote some of the earliest Blender tutorials, worked for Not a Number and helped run the crowdfunding campaign that open sourced Blender (the first one on the internet!). I founded BlenderNation in 2006 and have been editing it every single day since then ;-) I also run the Blender Artists forum and I'm Head of Community at Sketchfab.


  1. Dude that is amazing! It never ceases to amaze me how close Blender is getting to a professional set of tools! Now we can create super realistic animating creatures!

    Keep up the good work!

  2. First! :)

    Dang that looks sweet! You'd break a finger if you pulled it back that far, but I *love* what you've done with the shrinkwrap / skinning. Awesome stuff!

  3. Right now it is a tweak using shrinkwrap and a bunch of muscle ?

    But I really do like the result... It seems to work especially well for the shoulder e.g.

    THAT I would love to see hardcoded in Blender as a new kinf of deformations, next to Vertex Group and Enveloppe "Bones'n'Muscles"...

    Although rigging all that stuff must be a pain...

    At Juan Pablo, if you care to share some of your experience, I wouldn't mind trying to rig a female body that way :D

  4. Cool stuff :) and awesome work :) but I'm still waiting for real muscle system for Blender, to gain speed in rigging the muscles.

  5. pfannkuchen_gesicht on

    looks very good, but one thing: I think it wobbles too much on some parts.
    but anyway it's really good work.

  6. OK! I'm starting to get really creeped out now!

    I was thinking about render farms the other day, and on that same day, Blender Nation posted up an article about it.

    Then I was thinking about puppet animation, then that blues singing dog appeared!

    I was thinking about muscle simulation, and how I hope someone looks into it a bit more, and almost in the same hour!! THIS!!!!

    Even so, despite the weird back bending fingers, this is freaken awesome!!!

  7. Hehe thanks guys!! About the animation...I knew everyone was going to tell me something about those fingers, hehe. Let me put this clear, it an technical animation, it is not intended to be realistic. I just pulled the fingers backwards to see how the tendons reacted. And about the wobbling torax, hehe, that´s is his breathing animation, but it was 4 o´ clock in the morning and it really came out horribly, hehe.

    Well, go and download the rig, cause I would like some feedback regarding the controls!

    Thanks again for the comments. There´s a post about this here:

    NICE! What a look! I wasn't going to check it out becuase the last one took so much space, but I just gotta have this! I am going to learn this technique! (as well as get better at basic rigging, some of my deformations are terrible...)

  9. johnj, there nothing special to been done in order to make it work with make human. If you know how to use BlenRig you might be able to rig any model in a day or two. Actually, you can get it running pretty decently in a couple of hours, but if you wanna make very detailed tweaks you might want to spend more time with it.

  10. Quote from the page: "1 meter = 1 Blender Unit scale"

    It is a catastrophe that blender still has no unit system.

  11. should be good, but
    Mirror 1 - I can't make out the characters that have to be entered in order to download
    Mirror 2 - crashed internet explorer (twice)
    Mirror 3 - gave a 'file not found' error.

    Can anybody help?

  12. gary, that´s strange...

    Mirror 3 is down, that´s true, I´ve just erased it from the page. Mirror 1 is a Megaupload link, and mirror 2 is a Rapidshare link. Try downloading Firefox and trying mirror 2. You can also check if your Firewall or Antivirus are the ones that make IE crash.

  13. great looking rig although the jelly chest looks really weird. his ribcage should definatly not be floating about like it that while the muscle mass stays stationary its really odd

  14. I don't think that's a jelly chest rather the video just want to show how the breathing system work while doing other things at the same time.

  15. Oww! I'm not able to bend my fingers like that and they are bending in the wrong points. Strange.

    The knuckles look odd. They look more like pellets that are caught under the skin rather than end of the bones that forms the knuckle joints. Better improved that. What not make it an actual bone that move with the armature? After all if you extend your fingers straight, the knuckles should disappear. Seams no other means but to create an actual oddly shaped joint bone there

    Hmm! Muscle elasticity is completely absent. Every part seemed tense. None stretches or contracts. I hope an improvement can be made with the available to tools Blender has.

    And oh! Actually breathing is not made by expansion of the ribcage. That is wrong. If you just take shallow breath, minimal motion will be observed on the ribcage. The diaphragm would just push the stomach and intestines and thus we observe expansion and deflation of the belly. If deeper breaths are taken, The ribcage would actually just rise enlarging the available cavity beneath it making the lungs inflate. It just seems to expand because in rising the ribcage, we pulled the abdominal skin and muscles making them tuck in slightly. In short we should just be seeing the chest rise and fall along with other parts that attach to like the shoulders, and arms and the trapezius muscles. While the guy breathes. Do this seem impossible to achieve?

    Though compared to other means, this fared better.
