It took me a bit to figure this out, as I was initially doing something
more complicated like this before I realized I just had to pass
get_mesh_arrays directly to add_surface_from_arrays.
```
var arr_mesh = ArrayMesh.new()
var arrays = []
arrays.resize(ArrayMesh.ARRAY_MAX)
arrays[ArrayMesh.ARRAY_VERTEX] = c.get_mesh_arrays()
arr_mesh.add_surface_from_arrays(Mesh.PRIMITIVE_TRIANGLES, arrays)
```
