DirectX 9: Transform texture of one instance of a loaded mesh, but not others

In DirectX 9 I have a .X file which I've loaded and I draw several copies of it. I need to be able to alter the texture coordinates for each copy (e.g. give each one a different scale). Unfortunately because they're all the same mesh and use the same materials, it seems that tr开发者_如何学JAVAansforming the texture for one does the transformation for all of them. Is there a way that I can use to transform the texture of each instance of a loaded mesh individually?

• You could use a texture coordinate transform.

• You could clone the mesh.

• You could use a shader and scale the UVs in the shader.

You'll need to Clone the mesh in question, then adjust its information. This will prevent it from effecting the other Mesh instances.
