I’m running a render with rtrace but im getting weird results, almost like self reflections, whenever ab is > 1. Any clues what it might be?
Found the error. My reflectances were 60.0000 instead of 0.6000 . Keeping the post here in case anyone else makes same stupid mistake
ab 1 looks fine. (exposed to a 10k lux overcast sky and pfilt -1 -e -10 for exposure)
Same image with ab 2 (exposed to a 10k lux overcast sky and pfilt -1 -e -10 for exposure)
Same ab2 image with -e -15 in pfilt. Notice self reflections under ceilings.
It almost looks like it’s an inverted image!?
-ab 3 even more visible:
