oh, now what?

I rendered a file at the weekend and everything was ok. Now when I re-render (iether from saved IR and LC map, or recalculated) I get this strange thing.

Any ideas?

Are you making sure you are not using a precalculated map, or it is not able to find the map. Have you tried reseting vray and seeing if it still does this ?

closed an reopened, and all is fine. Weird.

Do you have any lights with the standard 3ds Max Raytrace shadows?

Best regards,

I am experiancing something similar when rendering DR with Irr & LC.
If I render DR with Irr & DMC then it disapears…
