Illuminating a Volume with Redshift Material?

Recommended Posts

Hello, I am curious if it is possible to illuminate a volume with the light emitted from the emissive channel of a redshift material. I can't seem to find anything regarding "volume contribution" within the materials and there doesn't seem to be much documentation on the subject. For example, embers emitted from a flame should illuminate the rising smoke.

No, that is a limitation of Redshift. What you can do, is turn the same object that has the emission matterial into a mesh light which will give you volume contribution and samples controls. This gives you a single colored light emission. You can go one step further, if your object has a material and UVs, and bake out the map on the object and the use that map to project multiple colors from the mesh light.
