Hello all,
I just noticed that a strange "banding" on most objects in my recent renders
was caused (?) by the .set file's Shadow-Bias-Absolute=ON/OFF choice being
changed to ON.
Has anyone else seen or know about this shadow artifacting?
TIA,
– Ron

This is related to how this setting alters the BIAS calculation. Consider a
scene of about 100 units a "base size". Take your usual bias setting and
multiply accordingly. For instance, if your scene now encompases an area of
1000 units, multiply your Bias by 10 to reach a good starting point. It will
take some fiddling. Set it too high and your shadows will detach from the
objects, too low and you get a banding effect.
