Well, of course this works, but its a little slow - using these many views..

There is also another way:

Code:

---

function blur
while(1) {
vec_set(screen_color,nullvector); //no background color -> old view visible
camera.transparent = on;
camera.alpha = 10;
wait(1);
}
}

---

That's the "core" of it - call "blur" and motion blur starts.
