I gave it a shot trying to remove the color from the Troopers after the Empire is up and running . Didnt work out as well as I planned. But that was a long time ago, and I've learned alot, so I'll try it again before I'm done.
BTW The chapter 7 clip as the troopers are marching. I added those marching sound FX. So its as easy as just moving them around til they match right. I might also replace it, if I come across a better marching sound.
