This was a suprise. I’ve been working in 1.5 for a while, and came back to this to make some changes. Somehow in going from 1.4xxxx to 1.5 I’ve screwed something up. Some of it looks ok, but what in the world are the blotches?
The trough light is a vray plane, and the cans are just cylinders with vray light mat. The pendants have vray spheres in them, and there is an invisible plane running down the corridor. The tv’s are vraylightmats.
Actually when using LC for 1st bounce, it is good to set LC for the 2nd as well. Also try using < Fixed > filtering and adjust the size of it, till you get a clean renderout.
Generally I wouldnt recommend LC for fiirst bounce for anything really detailed BUT it is damn quick.
And as for 2nd bounce anything other than LC is ignored
