Is there any way to cause (or fake) light emission from the fire within a smoke simulation? Obviously smoke doesn't work in Cycles but is it possible in BI for the flames to contribute light to the scene in the same way that FumeFX does in 3ds Max?

Alternatively is it possible to convert a flame into a cloud of particles in order to hack this somehow on a different pass?

  • $\begingroup$ Cycles will have Volume rendering soon (currently experimental in GSOC-2013-Dingto), so you might be able to do an emissive volume with that. $\endgroup$

  • $\begingroup$ @Vader Smoke can't be rendered in 2.70, but it can in later development versions (as of this commit) $\endgroup$

What I do is in the Blender Internal Renderer select the material that is going to have light cast on it. Then enable mirroring and turn down the glossiness. enter image description here

You can adjust the number of samples it uses for smoother results.

Sorry for the wait, lack of internet at my home right now.

I think that if you go to your texture influence properties for your domain object (voxel data), and check 'emission' it should work.emmision
