Can Blender Blend This?

[Fabier]

Well, ok, fancy title aside. Hi again, I figure since I made one post might as well make several more =). I have a question about the abilities of Blender. I used to have a technique for making extremely realistic fire, lightning, and smoke using the falloff shader in 3ds max. What this shader could do would make it so that the texture was "additive." It was semi-transparent, so when it overlapped with itself it would get something of a glow effect going.

Here are two renders I created using this technique in 3ds max.

My question is. Is there a way to mimic this in Blender? A way to make a material add to the brightness level of objects it overlaps with?

Thanks a bunch.

Yes. In the materials buttons, on the MapTo tab, there's a drop down for mixing properties for textures. You'd want to select "Add".

Hmm, that wasn't quite what I was looking into. That makes the shader additive to the other shaders currently applied to the object (which is important too at times... Just not this one).

Thank you for the reply, however. I think I found a viable solution by creating a shader and applying it to the emit button. That seems to have a simmilar effect.

Thanks for pointing me in the right direction ^_^.
