#UE4 auto instancing of dynamic actors

Testing auto instancing (aka batch instancing) and custom primitive data in #UE4 . It works with: run-time spawned objects, stationary/movable sun/sky, csm, df, static/stationnary/movable actors, physics (maybe more). Problem with inset shadows. Example with many cubes and very few draw calls. With moving objects number of draw calls is fluctuating, maybe it recalculates the “clusters“ time to time.
