Mesh Instancer

There are a few ways to get a Mesh displayed in a scene. The primary method is to create an Actor with a mesh, which gives you full functionality to manipulate your mesh. Geoms are the opposite end of the scale. They let you statically insert your Mesh into the scene in a very performant way, but they cannot be moved or manipulated.

However, sometimes you need some middle-ground, and that's where MeshInstancer comes in. A MeshInstancer is a stage node that itself can be moved and manipulated, but allows you to instantiate a mesh multiple times in a way that's fast, and uses much less memory than individual Actors. There are drawbacks though:

MeshInstancers are great for things like foliage, trees, or rocks - where you want to instantiate the same mesh many times.
