@Harlanq1990 I tested on our latest (5.4) which should be very close to 5.3, and I can’t reproduce the issue neither with ShadowMap or VirtualShadowMap. Here are the tests with different MFP values.
ShadowMap
VirtualShadowMap
Note that with ShadowMap we quality drop very quickly as you move away from the camera (cascade 1 seems to be really low res).
