Hi, I'm trying to make the CloneMeshFVF() function work by passing in a DWORD variable, and not a "#define" variable, and if I do that It always fails. For example


DWORD mesh_FVF =  D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1 | D3DFVF_NORMAL;
...
mesh->CloneMeshFVF(D3DXMESH_SYSTEMMEM, mesh_FVF, localDevice, &clonedMesh);

but if I have something like #define MESHFVF (D3DFVF_XYZ | D3DFVF_DIFFUSE | D3DFVF_TEX1 | D3DFVF_NORMAL), and pass that into the function it's fine. Please help, Thanks.

...what exactly is the error you're getting?

I'm not getting any error, but I'm testign the funtion with FAILED(), and it fails everytime I pass in a variable DWORD

Exactly, so what's the HRESULT returned?

Anyway, I don't see why that should cause an error. I suspect that you're somehow erroneously manipulating the value of mesh_FVF somewhere, before passing it to CloneMeshFVF. Try setting the value of mesh_FVF just before you call CloneMeshFVF, and tell us what happens.

Thanks :) yeah, that was it, I set it right before the CloneMeshFVF() and it worked fine, but why won't it work when I try to initialize it in the constructor? I am sure that I'm not manipulating anywhere before the call to clone (I searched the document for mesh_FVF, and it only found it in two places, first when I declare it, and second inside CloneMeshFVF()
