How do I go about changing the transparency of a texture in my pixel shader? Which parameters can I manupulate (does the COLOR0 contain an alpha value)? Do I need to do some "blending" for it to take effect or is blending the only aspect to it (if so does this imply that its impossible to do this in pixel shaders to blend with the render target)?
