uhm, is it late, or is there trouble with gradient backgrounds?
all of a sudden gradient environment maps render out as colored squares?!
no GI no nothing, plain default settings…
what’s going on, anyone else encountered this?
could you show an image of the problem?
yeah, it looks like this:
it’s very weird, there’s an empty max scene here if anyone would like to see it in action

If you use mapping other than “Explicit UVW channel” for the gradient map, for example “Screen”, it will go away.

Well for starters you have it set to explicit mapping channel.. and well the environment doesnt have any mapping. so here on the RC builds it renders white, if you change it to enironment mapping and choose screen it renders as expected.

ajajaj, how embarrasing 
i was right in my first comment - it was getting late…
thanks again guys, sometimes my mind just skips the obvious, i wonder where i would be without this forum? probably cleaning toilets somewhere
