Stain Mark on Render

[Iliada]

Hi,

I have been working on a project and started rendering, everything was alright, and suddenly a mark that looks like a shadow comes up on the image.
I have tried EVERYTHING. Turned all artificial lights off, natural lights off, made a new ceiling, repositioned my lights, changed global illumination from irradiance map to brute force... Nightmare.

Can someone have a look at it and help me, please???

Try turning hidden geometry on and delete if hidden lines appear on that area..

Hi,
Well, I checked that too and no hidden geometry on the way. =/

Well, I have tried that as well. No good =/

If you mean the ceiling then that is bad geometry without question. It looks like a boolean for those spots that has messed the faces up. Rebuild it with better topology and it should be just fine
Or post the mesh and I'll look...

I think so, bad geometry.. It doesn't affect materials without textures as far as i know but if you use texture map bad geometry causes issues..

Good to hear. It's a common issue - once you know it you always avoid it
