I''m having problems with blending. I''m trying to linearly interpolate between two textures using D3DTOP_LERP. The blend factor is located in the diffuse color component. The problem is that the FVF vertex formats only allow the diffuse color component to be a DWORD. I need a float. Is there anyway I can interpolate using a floating point factor? I know this is possible in OpenGL, so DirectX should also be capable right?
