UShader: Significant Shadow Acne with VPS #89

Open 0CCULTIST opened 1 year ago

Describe the bug When variable Penumbra Shadows are enabled, a higher amount of shadow acne is present than should be expected. Disabling VPS fixes the issue.

Not quite a bug per-se, but just a result of my ongoing fight with the shadowmap bias. I plan to improve that in the future though
