Open chancemcdonaldsims opened 3 weeks ago

chancemcdonaldsims commented 3 weeks ago

Tested versions

I only testing with godot 4.3

System information

mac os 15.0.1 Godot 4.3

Issue description

Some materials cause graphics issue that are hard to work around. image

Steps to reproduce

the issues have happed when things involve transparency. In the photo included it is created with CSG volumes. When working with one the graphics issues happen. The artifacts are high frequency and hard to work with.

Minimal reproduction project (MRP)

issue.zip Rotating around scene shows graphic issues. Could be around z fighting issues.

Reproducible on both macOS and Windows. There's some visible Z-fighting between selected CGSBox and resulting shape.

The interference pattern is different (squares on M1 Mac, stripes on NVIDIA/Windows), but this is the same effect.

@bruvzg So is it a bug or not? I don't know if this is avoidable but I don't recall any issues with CSG in past. I also had similar rendering issues with skinned meshes in Godot 4.3 when the meshes had transparency enabled.

Just to provide more context this video provide more information on experience. It is actually sickening to watch this effect for me. I have a large monitor 43" and it produces a flashing effect that may effect people with disabilities more (like epilepsy). I actually having to switch to Blender to prototype because I can't endure effect anymore.

This is an imported model from mixamo. It has a similar effect so I think this is more than z fighting.

Yes, I would consider it a bug (just not a macOS specific).

This might be something completely different, in case of CGSBox it's likely cause by selection and shape having face in the same plane (both are generated from the same data, so this is expected, we probably should add some offset to the selection), there's no obvious reason for the model case (and seems like no transparency involved), not sure what's going on.
