Bump and Denoiser

[Lubo]

Hi there,
what is the best way to keep a bump-texture still visible in spite of using the denoiser?
My Scene is very dark and i`ve got a lot of noise in the begining, but after watching a few tutorials how to get rid of the
noise, I´m fine with the result except loosing some important bump-structure. The bump washed out, looks blurry.

Best regards

Difficult to say without some screenshots or an example scene, but probably you don’t have enough sampling for AI Denoiser.
Try to double the max Sampling vaslue in the Kernel, to see if it solves.
