I have a scene that has at most 100 light sources in it but some of them are lightmaterials.
Just a query. How does the lights in scene stats relate to lightmaterial sources?
It think i have over 3000 lights in the scene but its a tiny room with two lamps and a ceiling grid.
Any ideas?
I think each face counts as a light when it comes to lightmaterial
ooh good call that makes sense!
what, this dialog works for you?! It always shows zeroes for me 
Cant tell if sarcasm haha.
The rollout in the render progress dialog works for me yes.
I implemented it sending numbers in there, then checked it and it always shown zeroes for some reason. I kept the code in, in case it worked at least in some other versions of 3dsmax. Apparently it does
Ah, well yeah its working fine on mine 
Guess its one of those bugs/features again haha
