Dynamic shadows artifacts

Found easy fix for this.

FScreenSpaceData ScreenSpaceData = GetScreenSpaceData(ScreenUV);
float NoL = saturate(dot(ScreenSpaceData.GBuffer.WorldNormal, DeferredLightUniforms.NormalizedLightDirection));
Settings.TransitionScale = SoftTransitionScale.z * lerp(0.1, 1.0, NoL);

that actually looks great.
but before getting too excited, could you show something with more irregular geometry than a sphere? I wonder how non-convex self-shadowing will behave with this fix
