Hi,

@pierred_unity suggested I post this here too.

I am experiencing a distinct difference between GPU and CPU light baking.

My system has a Ryzen 9 3650X and a RTX 2080 Super.

Choosing Optix or OpenImageDenoise makes no difference for the outcome.

Best regards Floggy

I get the same Results on 2019.4.20f1, 2020.2.4f1 and 2020.2.5f. Seems to be something fundermental.

I tried them all in accending order to maybe get rid of it.

I was about to suggest that you’d take a look at this pinned post, but I doubt it would help in your case. It’s as if the entire scene is somehow invalidated by the GPU PLM. As strangely enough, it repros both in 2019.4 LTS and 2020.2…

It would help if you could submit a bug as per these guidelines, so that we could investigate on our end.
