Volume2 Shader Test

Hello,

I'm doing some tests with the Volume2 Shader, I really like multi scatter options and colour control.

Voxels from Houdini / Pyro sims :

Explosion Test

This one is from an explosion sim, but wanted to try a cloud shader ; used 6 volume bounces + multiscatter, and black to white gradient mapped from density to color to fake the "dark edges" effect.

I'm not so sure about best anisotropy settings for clouds ?

It would be nice to have an easy solution to separate indirect light from volumes & rest of the scece (for explosion / fire)

Thanks.

Re: Volume2 Shader Test

Hi Paul,

the volume emisson should be visible in the Incandescence AOV.
Otherwise, all bounces can be easily separated using LPE. Check the AOV and Light Path Expresion sections in the doc.

Very nice rendering, indeed!

Best!
Ben
