Material node DestColor from UE3

I am moving some materials over from a UE3 project that use DestColor. That node doesn’t seem to be available in UE4. Is there an equivalent?

IIRC DestColor returns the colour of the pixel behind the one you’re trying to render right? (from camera’s perspective). Try using ‘SceneColor’ instead, and see if that gives you the same results.

You will struggle to port a lot of UE3 materials because the renderer is fundamentally different.
