Fyre Posted January 20, 2016 Share Posted January 20, 2016 I was wondering if there was any way to bake lights and or shadows into voxels/volumes. The only thing I can think is an attribute transfer from a shader, but I dont know how this would work. Trying to cut down on non-dynamic volume rendering times.

Juraj Posted January 20, 2016 Share Posted January 20, 2016 (edited) Hi, I don't have much experience with rendering volumetrics but two things crossed my mind that could help you. Cloud Light node which seems to bake lighting but I have never used it. Second thing is to use deep shadow maps for lighting (if your lights and clouds are static). I am curious about experience from others with speeding up rendering volumetrics. Juraj Edited January 20, 2016 by Juraj Tomori Quote Link to comment Share on other sites More sharing options...
Fyre Posted January 20, 2016 Author Share Posted January 20, 2016 (edited) Thanks for the response, I'm currently using cloud light to some success, however there are issues with the cloud light and instancing, which is what im currently doing. I've also tried using deep shadow maps, but for some reason i cant get it to write volume bounces, only direct shadows.

fathom Posted January 21, 2016 Share Posted January 21, 2016 deep shadows can't do bounces. they're images "rendered" from the viewpoint of your light, so they only capture depth directly along the primary light ray. Quote Link to comment Share on other sites More sharing options...
