I stumble across this today…
Beside the bug of affect shadows not working when a refractive materials when in a multi sub-object material, fog seems also not to be working…!
can anyone confirm this?
is there any fix?
can you post up a scene or some images to see what the exact problem is?
ops…miss that one!
thanx paul!
yeah its all sorted now
Oh, I´m lucky to have come across this thread, I´m rendering a headlight right now with all parts in a multi/sub, no wonder I thought that it looked wrong
