ID3DXSkinInfo::GetMaxFaceInfluences

Gets the maximum face influences in a triangle mesh with the specified index buffer.

HRESULT GetMaxFaceInfluences(
  LPDIRECT3DINDEXBUFFER9 pIB,
  DWORD NumFaces,
  DWORD * maxFaceInfluences
);

Parameters

pIB
[in] Pointer to the index buffer that contains the mesh index data.
NumFaces
[in] Number of faces in the mesh.
maxFaceInfluences
[in] Pointer to the maximum face influences.

Return Values

If the method succeeds, the return value is D3D_OK. If the method fails, the return value can be D3DERR_INVALIDCALL.
