Tutorial: Fake Volumetrics

27

fire ball.Some of you might remember Colin Litser's cloud creation tutorial. Which took a look at creating volumetric cloud effects in Blender. But how about taking it a step further. Who hasn't wanted to blow up a building in a fiery explosion? (in 3D of course!) Or how about launching a comet into orbit?

Salvador Mata Rodríguez has provided us with an excellent tutorial on how to begin to do just that. The tutorial takes a look at creating volumetric smoke and fire effects in Blender using a mixture of procedurals. The smoke would make an excellent start in cloud creation.

Find the tutorial here.

  1. There is one step that some folks might get caught up on. He state: "The next procedural wil be a Blend again, but this time set to Sphere mode, with their map inputs in Win, Sphere and Z, mapped to a Alpha channel with Substract blending mode." But the image shows Nor, Flat not Win, Sphere. My suggestion is to follow the images over the text if they contradict.

  2. The lightbox plugin (the one that's doing the fancy image display) is causing some problems these days; I'm not sure why. I've disabled it for this post and the link is fine now. I'll look into it later this weekend.

  3. Thanks :D I hope you like it and found it usable :)

    Also sorry for any mistakes :S, english is not my native. I'll do all the corrections to the tutorial ;) and publish the fireball blend file.

    :D

  4. Brian try the same but this time with a metaball instead of a sphere(and adjust the overall size and make rendersize very low)

  5. First, I think I'm going to tweak the alpha prior to trying that. I'm pretty sure there might be some issues with materials since it will map to the whole metaball group. Unless that has changed since last I tested metaballs.

  6. I like engineering effects like this... I think if you use a Fresnel transparency ramp (or any other transparency ramp for that matter) it'll remove some of the artifacts.

  7. Great Tut!!!
    ...and like Salvador Mata Rodríguez says at the end of that tut:

    Ready! We don’t have fire/smoke plug in for blender, but blender itself can be capable of do almost anything you can imagine! Blender is great!

    He´s right - but somtimes it is good if someone explain which way you can go,
    becaus there are so many ways...

    This is an example of my try to create an boom:

    well, Only corrections for some typos, I didn't notice that from Eugene:

    "...There is one step that some folks might get caught up on. He state: “The next procedural wil be a Blend again, but this time set to Sphere mode, with their map inputs in Win, Sphere and Z, mapped to a Alpha channel with Substract blending mode.” But the image shows Nor, Flat not Win, Sphere.

    And added some extra files I mentioned before :)
