Anyone else encounter this? I only see it in packaged build, but it’s persistent!
If it helps, here’s some notes on my project’s settings:
- No Lumen, no Nanite, no VSMs, no raytracing
- Baked lighting, using all Stationary lights. Some dynamic lights from gameplay elements.
- Modified shadow configs:
- r.Shadow.MinResolution=64
- r.Shadow.RadiusThreshold=0.001
- r.Shadow.TexelsPerPixel=16
