[PTNext Beta07] Strange geometric shadow artifacts when indoors

Images attached show comparison with PT21

When in exteriors no issues occur. However, whenever entering an indoor or area with a ceiling, these artifacts appear on the upper third of the screen. They remain on the top of the screen - so they disappear when I look at the ceiling.
They disappear when I switch to PT21.

Update from more testing:

If I load a save that is already within an interior, no artifacts appear.

Yep, I've had this happen too, usually on the first load. Happened outdoors the other day as well. It's like the shadow gets attached to the camera and just follows it around. Reloading the save or switching to PT21 always fixes it.

ty, trying to reproduce 😊

EDIT just letting you know I'm going to be pretty busy until the weekend

Captured a video of what I experience outdoors, hopefully you can see it (sorry for the long load at the end!) https://drive.google.com/uc?id=1k1lqg0b-OrrAoSAHwGrQrLylJDhO-dMy&export=download

Hope that's helpful in some way. I'm trying to remember, but it seems to only occur after a new install of UltraPlus? Goes away after a few reloads.

I am noticing the same. I am running 4.0-rc1 in the PT Next mode with ray generation active.

Certain lighting conditions cause this weird shadow to appear. This is noticeable on some containers and in Jackie's garage during the Offrenda quest.

If I toggle the debug option 'Enable separate denoiser' to off this shadow disappears. Disabling the denoiser from the 'main' page does not do this. All other mod options are default for PT Next.

Chosen main settings:
PT Next
Insane Quality
16GB VRAM

ty. i can't access this video 😊

@erbkaiser hmm, Enable Separate Denoiser on the debug page is exactly the same as on the front page 🤔. just to check you don't mean Enable DI Denoising or Enable Custom Denoiser ?

[erbkaiser]

Sorry, I was busy looking for the cause in the debug options and I didn't notice it was the same option.
It is indeed the RTXDI denoising from the main page. Disabling that when the bug occurs instantly clears it.

[erbkaiser]

This is what I was seeing outdoors, for the record. That entire shadow disappears if the denoiser is toggled off.

It looks like the stuck shadow is generated during a save game load where the outdoor sky or skybox(?) is visible. Makes no difference if game time is day or night. Also keep in mind: the player's y-axis camera angle is reset to zero when loading a save, so saving the game while looking at the ground or sky won't have an effect for fixing or reproducing the bug.

Bug still present using 4.3.1
