Title: White leaks - Intel denoiser
Post by: zilviz on 2021-03-31, 17:27:57

Hello,

Having some issues with the Intel denoiser. After render is finished with Intel denoise I receive some strange white leaks. This only occurs with Intel denoiser, but with NVIDIA or Corona High Quality denoisers no issues. It looks like light-leak but it isn't, because I turned off all lights and checked everything in terms of geo - still those white leaks exist. Also, while rendering is in the process - no white leaks visible, only becomes visible when Intel denoising starts. Any solution? Thank you

Image 1 - Intel denoiser
Image 2 - Intel denoiser with turned off lights (still visible white leaks)
Image 3 - NVIDIA or Corona High Quality denoisers (all good)

Could you send us a scene where this is happening?

Should I post it here or send it where?

Up to you if you want to post it here - the link to the uploader is in Marcin's signature if you want to use that, though :) Just be sure to come back here and tell us the filename. Thanks!

Does your walls have thickness? Always first check thickness if you see light leaks.

The filename: Intel denoise.rar

Yes walls have thickness. Also, I added Image 2 to show that turning all the lights off still visible those white leaks.

Thank you, this seems to be due to a combination of things. I am reporting this for further assessment.
