New one issue (or maybe it is part of old one) make Adjust Color node to produce error on output of bitmap. Issue may be bypassed if you will output imagge by Libarary Output.
yes - a minimal project file showing this issue would be very helpful, as I can’t repro it here.
I suspect this is simply a value going out of range but want to make sure the solution fixes it - which I can’t do if I can’t repro the problem in the first place
I’ve tracked this down. As predicted, it was an out-of-range color value. The Adjust Color device transforms RGB to a LAB colorspace to do its operation, and float point precision sometimes means that things don’t quite come back where you expect them.
