I know,i can use different particle systems,like particular or prarticle world,but i think of it as of some kind of a sphere…,so i could rotate my camera in any dimension and direction inside it…And flat backs won t let me do it!=( Bytheway another example i can remember is from the new Star Trek movie,when there are end credits,and camera pans from one planet to another,a bit too fast,but still…Well,any ideas?=)
