strange artifacts with denoise activated #169

Closed dirkk0 closed 1 year ago

dirkk0 commented 1 year ago

Hi!

First of all - thank you for this tool, it's fantastic!

Then: I experimentally switched from Blender 3.3 to the latest 3.5.1. The good news is - it still works! The not so good news is: activating the integrated denoiser results in (presumably) mixed up images, like so: 2023-04-28_16-00

Without the denoiser, it looks like that: 2023-04-28_16-01

Doing the same in Blender 3.3 (add plane and icosphere, acivate lightmapper for the whole scene, add denoise) works perfectly.

I wonder why that is?

Thanks again, Dirk

PS: I can provide the files if needed.

Hi, thanks for checking this out. There definitely seems to be a bug with the internal denoiser (they've probably changed something between 3.3 and 3.5 related to the compositor). In the meantime, can you check if manually using OIDN works? (Package from here: https://github.com/OpenImageDenoise/oidn/releases)

Thanks again!

Hi again, I think I might have fixed the issue now - Could you test if it works for you now?

Thanks

.. man, you're fast! :) I will test as soon as I'm back on my machine! thanks!

works like a charm! thanks!

I had this issue as well. If OIDN can be used as a workaround, shouldn’t this issue be kept open to further investigate on why Blender’s standard denoiser acts like that, and what should be done in consequence?
