If i set the Shadow settings in Babylon Sandbox to high and use a Filter site of 0.00001 in PCF mode.
I still dont get that crisp shadows. We would need more. Even if its crawling down to 1FPS.
We use those settings so render out UI elements in 4k resolution.
Please make an Option for ultra high Quality Shadows. Performance doesnt matter.
Maybe Raytraced Shadows are an option?
