Dynamic shadows artifacts

• Lightmass is Unreal’s solution for static lighting and has been for literally a decade, it is an editor-only tool, not a part of the renderer. “Lightmass 2.0” has been strongly hinted to be a GPU-based, potentially path-tracing based evolution of Lightmass, it will still be an editor tool, not a game runtime component.
• RTGI cannot replace static lighting because RTGI, as the name indicates, is dynamic, not static, and static lighting is a crucial feature of a game engine. RTGI in UE4 will now come through real-time ray-tracing with DXR.

This issue here has absolutely nothing to do with either Lightmass, Lightmass 2.0, or RTGI. It is a shadow filtering problem. Nothing more and nothing less. Please read more into this matter before arguing.

I know that this is about shadow filtering and nothing GI related. Ahh, what I am saying is that development of RTGI/Lightmass or ANY other bigger lighting solution is probably reason why this is not getting love and it will eventually be improved together with some other, bigger feature.
