I have some artefacts on the shadows in penumbra from distants objetcs.
When I move, there is persistents (fews milliseconds) black large spots behind the objects on shadowed areas.
My english is not enough good to well explain what’s the problem is, so you can watch this short video:
Black spots remains behind the tree after moving:
My light is dynamic :
Dynamic Indirect Lighting ON
Cast dynamic shadows ON
Cast static shadows OFF
Ray Traced distance field shadows ON
In Project Settings: Generate Mesh Distance field is ON
UE : v4.10
Thanks by advance
