For each set of camera parameters, we have this (values differ slightly between various cameras): MinShadowRange=(0.5) MaxShadowRange=(250.0) ShadowSplitRatio=(0.920) ShadowParams=(0.0001, 0.0, 2.0) ShadowParams=(0.0001, 0.0, 8.7) ShadowParams=(0.0001, 0.0, 36.0) ShadowParams=(0.0001, 0.0, 150.0) MinShadowRange - must be greater than 0, otherwise shadows won't be shown. Didn't notice any other influence (0.1, 10.0 or whatever... as long as it's lower than MaxShadowRange - nothing change). MaxShadowRange - maximum range from camera target within which shadows will be generated. Im more curious about those two: ShadowSplitRatio ShadowParams=(a, b, c) What is their function and what a,b and c mean for ShadowParams? I tried for myself to see how they behave with different values and it looks that ShadowSplitRatio have some effect on shadow quality/blur but apart from that, I couldn't come up with a reasonable explanation.
