@thomasp Yes, the painterly effect is an issue with denoisers for sure (in all apps that have them). It works better in some cases than others (scenes that require fewer samples to converge tend to be more stable). You can set the samples per pixel setting higher if your GPU can handle it, which will give cleaner…
A coworker of mine was talking about inverting the same image and setting a blending mode to lighting info in an image. Does anybody know about this? or have useful tips on the subject?
