That's still not single surface though. One set of mesh data yes, but creating copied entities still creates multiple surfaces that are rendered seperately.
For example, copying a sprite thousands of times will not create a single surface sprite.
For meshes you can use AddMesh which will automatically combine surfaces that have matching properties.
