	D3DXMATRIX textureMatrix;
	D3DXMatrixIdentity(&textureMatrix);
	D3DXMatrixScaling(&textureMatrix, 0.5f, 1.0f, 1.0f);
	m_pD3DDevice->SetTransform( D3DTS_TEXTURE0, &textureMatrix );
  
The above code works just fine, but using D3DXMatrixTranslation(), fails to move the texture coordinates. What am I doing wrong? Any information or links relating to transforming texture coordinates would be great. I have already checked google and the MSDN (that''s how I have gotten this far), but I am stuck here. Thanks in advance, Mike

Thanks for the link, NE1. Texture translations now work. My goal is to be able to simply specify a source RECT to use from the texture to apply to my texture quad (I''m writing a 2-D engine).

Another question: Has anyone compared the performance differences between textured quads and ID3DXSprite''s?
