HW model instancing

Trying to create model instances. I have been tested different codes with no luck.

Now I try to change this https://github.com/Eastrall/MonoGame-HardwareInstancing
to render model instances. Removed geometryBuffer, indexBuffer and bindings.
Instead I load model (earthM (just a ball), 1 meshpart), and use its IndexBuffer and VertexBuffer and try to render it. But nothing shows up.

Only CubeMap.cs file modified, modified file here:

(tested w10, newest monogame, dx&gl)

Ah, seems to work after all.
My models was so small that I didnt notice them.
