Hi,
im making the move from managed dx to proper dx with c++ and I have run into a bit of trouble when it comes to turning the mesh data I have read in into a proper mesh.
Im sure the problem is at the final level where i lock the buffers and copy in the data because all the attributes, vertexs and indices are correct.
Bellow is the mesh create code and the vertex structure im using, any help or a point in the right direction would be excellent. Cheers,
-Dave
