So, I’m trying out doing renders with a section plane, since i have a small room to render, but when i do it, some weird grey geometry appears and i dont know what to do.
When i move the position of the plane, it can change to a different shape. It is not some hidden geometry though, everything is visible, there are no hidden objects.
Weird thing about it, is that the problem disappears when i delete the ceiling. I made the ceiling few times, in different layers, also tried it in different models but its always the same. I checked all the lighting, nothing seems to be the cause.
