> Oh, interesting. GetParameterByName() failing afterwards is probably an indication that the SetRawValue() call overwrote parts of some internal data structure and broke the effect object to some degree. BTW, you're supposed to set texture parameters to a IDirect3DBaseTexture9 / IUnknown pointer (and similarly the value for a string parameter should probably be a string pointer rather than the string contents).
