Title: Volumetrics - include/exclude
Post by: Geezer on 2017-11-19, 14:39:47

Hi,

Any ideas how to exclude lights from participating in volumetric fog rendering?
I still want them to affect the scene but only render volumetrics with the selected lights.
Thanks,

Are you using global fog or a box/other object with fog material? In case of object, you could probably exclude that object from a specific light.

I was using the global fog method but will try the box method you suggested.
Thank you,

I have varying luck with this.   I can still see some lights in the volume that have been excluded from the geometry on which the volume is applied.   I can't figure out why.

Can you post some image, or even better a scene, showing this?
