hi doc, It's a plausible theory, but there's a problem. The lights are spotlights and the cr2 saves with all the other parameters, like AngleStart/AngleEnd, etc. It's only those two which are missing. I tried your other theory, by exporting the ground plane as an obj, the re-importing it and raising it slightly. But I didn't see any difference. Maybe I have a weird floor. I mean, everything else I have is weird, so.... mac
