Hi,
Am trying to setup Light groups in Houdini for Arnold and it doesn't seem as straightforward as in Maya.
I add the light group name to the light, add a custom AOV using an LPE to pickup the light group. When I test this in render view it works and strangely even with just one lightgroup AOV created, it automatically makes light groups for all the other lights.
When I render this on the farm the frames come back completely blank.
The docs seems a bit vague on how this should be setup in Houdini, does anyone have any ideas?
thanks,
Justin
You don't need to use an LPE.
If your light group name is "red", then add an AOV like RGBA_red (if you want the red light contribution to the beauty). Or diffuse_red if you want just the red light contribution to the diffuse.
