Maximum number of scene objects ?

Hi all,

Simple question, is there a maximum number of procedurally generated meshes I can bring into my scene? At any one time I might have between 200 - 600 meshes visible, attached to a single actor that I’ve spawned and retained.
I’m noticing that as some new meshes come into the scene to be rendered some of my older meshes are being deleted or hidden (I don’t delete them anywhere in my code at the moment).
So I’m wondering if its hitting some maximum object count or similar.

Any ideas? Thanks!
