32 bit comp produces artifacts

[Chris Wright]

compander enables 8 bit effects to work in 32bpc by compressing the median values, but that won’t work in your case. Levels with clipping on 32bpc literally deletes above and below values so there’s no wrap around of color, which works for me a lot when I have colors I want to clamp for special blending. BTW, did it help your problem?

Yes, this method did work. I had tried the compander before so I was not sure this would do it. But you seem to have this figured out. Those pixels where so clipped they were just being deleted huh? The paint strokes where being applied in a small area maybe not allowing any room to wrap? Either way you fixed it. Weird that we had to clamp the paint comps, I am OK with clamping those paint comps. I guess it gets tricky with the paint tool, and float? However this helped me. Thank you.
So all I did was apply the Ind Levels and clip the black and white(on). Can I use normal levels also, as it has the clip pull down menu as well?
So all you had me do is clamp the values in the paint patches that wheres tearing? Is that right? Just so I understand the principle of this and not just blinding apply clamps.
Thank you again.

The pixels were wrapping around and mixing back into the visible pixels again. Ususally this works without incident, but some plugins aren’t programmed to handle true 32bpc, and apparently, paint is one of them.

Normal levels should work with clipping, but I only use the individual controls so cannot guarantee correct programming 100%. You only have to clamp the paint comps and you apply the clipping after, not before. Apply it to all the paint comps so you don’t have to wait to render to find out where the errors are.

Since it’s working for you, just keep doing the same thing. I’m glad to hear my trick worked.
