Thanks, the per object shadow map thing could potentially be useful.
I already have a scene capture setup to capture scene depth at the appropriate times. My issue is setting up unreal to use those shadow depths properly.
Creating static shadow-maps at runtime. Possible? - #11 by somawheels this post shows where i am at. My shadows dont look the same as unreal’s, they have bias issues, and the blur method i am using too expensive for my liking.
