I am having issues with my scene. I created a sand dune sort of mesh and everything is all good. I add in an HDRI and then get this:
As you can see, the sand has some sort of weird shading issue which I believe is called "shadow terminator artifacts". I've only seen three solutions:
- Up the mesh density (didnt' work, even with my high poly 1mil mesh i got these artifacts)
- use the shadow terminator removal tool in blender 2.9 (Also didn't work, the shadows became too large)
- Disable smooth shading. (Did absolutely nothing)
I honestly am confused and have no idea how to fix this. The scene is literally just an HDRI rotated around slightly.
One thing i will note, is that the shading issue goes away when i have a more diffuse HDRI (or none at all)
I also have tried switching out the HDRI for something else and still got the artifacts. What else can I try?
EDIT: forgot to mention, I don't get this issue when I render with EEVEE.
