To get that effect in the 1st Blitz sample is not very difficult at all. The method I know requires you to render two camera views, 1 that is normal and 1 that is very very very blurred. Then make the blurred one 50% transparent (or less) on a layer on top of the regular camera. It gives that sort of dreamy blurry effect, although the shapes are still distinctly made. I don't know if this is possible with 3dgs, and if it is it I have no idea how to do it Try it out with a screenshot in photoshop, it looks really neat. (I'll post something here if I have the time later)
