oh, thats nice of you!

what I didn´t catch is where you plugged in the rayswitch -> into the materials shading group(environment) maybe?

I found a solution similar to yours, but I´d like to have a more global workflow in the future, because scenes often consist of like 100 different materials. right now I plug either a mirrorBall with same HDRI (rotated) into the shading groups environment to get different reflections, or the mia_envblur for faster calculation of environmental reflection casted by IBL itself.

to get around the envBall workaround it would be nice to have like 2 IBLs in the scene at the same time and rotate them as needed for global reflection and lighting. I tought that would be possible with the rayswitch, but I think I missunderstood the concept since rayswitch seems to be just a shader for objects, and not a switcher for deviding lighting/reflection.

thx!
