Chaos / Root Proxy Data

Hello there,

I need some clarifications.

So in the following image I have placed in the level GC 3 times, made out of the same type Static Mesh.
I select “Proxy” in the “Custom Renderer Type” and I add the static mesh as “Proxy Mesh”.

Now, if I will duplicate the GC multiple times, will it render it as ISM (1 static mesh)?

I want to duplicate the same objects 2400-3500 times and I try to optimise the simulation.

Thank you!
