I'm recreating the explosion of the DeathStar from the Star Wars Special Edition Movie for my Special FX Final and I have a question; I'd love it if someone could answer before Friday. I need my explosion to be in the center of the Ring Of Fire (Concusion Effect), however, when I tried compositing it in AFX the Explosion is just sitting in the middle of the outer Ring; it is supposed to be inside of the outer ring. I hope I'm not too confusing anyone with this. How do I fix this Problem? Is it with Alpha Channels? If it is TELL ME HOW TO USE THEM FOR THIS REEEEEEEEEEEEEEEEEEELLLY FRUSTRATING ORDEAL. I attached a sample. This is not the final rendered image. It is just to show you guys the problem. I hope that you can see it. By the way this is the best site I been on since.......FOREVER!!!!!!
