HDRI Sky has weird visual artifacts
Created by: aclave1
Godot version: Version 3.2 Works fine in 3.1.1 OS/device including version: Windows 10, Desktop PC GTX 1070 Issue description: In godot 3.2, when using a panorama sky with an HDRI panorama, weird artifacts appear. In the screenshot I posted, the model has albedo and roughness textures on all the meshes and also metallic on the armor. I am noticing these issues with 2 different meshes, each of which is a rigged character mesh.
I'm not an expert in lighting or graphics/hdri, but I think the problem is related to the resolution of some framebuffer in a shader? When i look at 3.1, I can clearly see very fine reflections from the hdri in things like the metal, and the clothes look very flat as expected. When I look at 3.2, the shading looks pixelated and stretched.
Steps to reproduce:
- Open a project in godot 3.2 which uses an HDRI panorama skybox
- Import a textured model
