Shading bug.

Hello again, kirgman.

Reporting a small bug.

A while ago (when the engine wasn't supported by the RTX 5090) I encountered this shading bug in another stadium model. But with the release of newer versions and support for the RTX 5090, it disappeared.

It hadn't reappeared until now. The thing is, if you look at the attached images, you'll see that it's a sequence of images that moves from one seat to another, and as it moves further away from the concrete wall, the unwanted effect disappears. It's as if it's related to the camera distance, but only with certain materials or objects.

Thanks in advance.

Edit:

I've noticed that it might be related to the engine's internal clipping (if such a thing exists), since manipulating camera clipping affects this artifact in the render.

Hi Jiv! And thanks for report!

So far I have detected
1) animated denoiser artifact
2) flicking stairs lighting - probably denoiser issue or something that was fixed with 0.718
3) the right wall details. I hope it was fixed with a recent bugfixed 0.718. But in case it's not please can you send me a scene for investigation?

It's also strange that zero camera clipping value produces an issue. I probably need a scene (or a part of it) to investigate for proper bugfix

There is a change with the new version.

It doesn't eliminate the artifact, but it reduces its intensity.

As soon as I have a moment, I'll prepare a basic scene for you to investigate.

Thanks and regards, Kirgman.

Hello again, kirgman.

The update from 0.717 to 0.718 brings significant changes to some materials.

I'm sorry to hear this.

Thanks in advance.

Oh, there is quite a lot in this scene. Definitelly I need to investigate. Probably just the copy of objects in the vicinity of the camera may help.

The 0.718 adds the coat_bump_map. But if it's not assigned it shouldn't change anything. Can you please send me this material with wrong reflections too?

Good morning, Kirgman.

I've sent you an email with a link to the scene. As usual, I'd appreciate it if you didn't share the scene with anyone.

The selected camera shows the banding error in the footage.

And the second camera has the correct shot to observe the footage change with version 0.718 of Centileo, compared to version 0.717.

I hope this helps.

Thanks.


EDIT:

The geometry is a bit messy (inherited), I've remodeled and cleaned the mesh, in case that could be what's causing the problem, but it persists.

Thank you Jiv for the scene file, I will review the case as soon as possible. The file protection is guaranteed!
