I think we deviated from the main topic. It wasn’t about improving the quality of the AO, but about a completely different kind of effect. The Screen Space Curvature can be emulated with AO but it would require a absurd amount of samples (100 or more) and as you said - it would run like a potato.
I just want common post-process that bump-up small details like contour of clay stroke, edge of flatten stroke, alpha details ect. Screen Space Curvature is great for such kind of things and it’s super cheap (as opposed to SSAO).
So I am asking if you are willing to implement/restore this kind of post-process?
