Uhmm are you talking about this effect?:

Code:

---

  

var blure;function swtich_blure(){  if(blure){camera.transparent=off; blure=off;} //if on, then switch it off  else  //else switch it on  {    camera.transparent=on;    camera.alpha=60;    blure=on;  }

---

But doesnt this code makes the whole screen blurry?
I need just the propellers to be blurry nothing else

Any ideas?

Thanks
