Need info on Hierarchical Instanced Static Mesh Components

I looked at the implementation a bit. It has a tree data structure that gets async rebuilt on the fly according to LODs and MaxInstancesPerLeaf var. Rest of it is basically the same as InstancedStaticMeshComponent, as it is derived from that anyway.

Afaik, you can just use it like a normal ISMC, it does the tree building by itself, just calling the AddInstance should suffice as it is overridden.

So normal instanced meshes don’t handle LOD’s at all, or just not quite the same or as well as the new version? The MaxInstancesPerLeaf sounds like something specifically for foliage, so I wonder what that would do for a normal mesh…

When I get some time from my current work I will see if I can push it to the limits and compare that to my current setup to see if I see any difference.

Thanks for the info!
