Title: Multi-pass pattern noise
Post by: sszyszka on 2025-07-25, 06:58:00

Hi,

I am getting a repeating noise pattern in some multi-pass passes. This is a screen shot of the shadow pass, but getting the same thing in the reflections pass on this image.

I used to know how to eliminate this, but for the life of me can't find the solution anymore. Any help would be greatly appreciated.

Result is the same in IPR and final render
No denoising
Adaptivity is on

Maybe
- unlock sampling pattern, change frame#
- set "Light samples multiplier" higher (4)
...

How long was the rendering we see in your screenshot? (how many passes were rendered)
