There are many problems with doing motion blur. For example, if you had an object fly past the user (standing still), you would want it to blur that object, yes? However, the PP shader doesn't know which pixel to move, or which dirrection to smear them, so I take several shots and mix them newest first, oldest last.

However, that method does not actually "blur" objects, it just creates several mixed copies of it, which "sort-of" blurs it

I havn't added anything to the shader (besides lerp() for better mixing), because I don't really know what to do next. If anyone wants to, please feel free to take my release and continue it.... I'm out of ideas and time
