Anyone know how to set a custom vertex shader when rendering a .x file mesh with DrawSubset? I see that you can set the FVF with clone mesh, but can't find where it's setting the shader in there.

DrawSubset doesn't set anything related to shaders, all it does is a DrawPrim call. So set your shader the same way you would if you weren't using a mesh and it should work fine.

On a related note, say I call DrawSubset and its drawing my mesh as a triangle strip. What if I want to render it as quads? How can you set the primitive type for DrawSubset?

You can't set the primitive type. DrawSubset is a wrapper to make things easier, to do that it sacrifices flexibility. If you need additional flexibility, you can get direct access to the IB/VB of the mesh.

There is no Quad primitive in D3D.

thanks DH

thx for the tutorials too...can be hard to find easily understandable d3d8 source.

lemme see if i can get this model to work with my shader now...
