STRAT, thanks for tips. but i can get a camera to follow a path and all. i created a line and smoothed the corners on it, making it circle and go through my object (it is a single object composed of extruded parts so that it looks, very simply, like buildings or something). i then created a dummy object, and made its path the line i made first. i then made a camera and and linked the camera to my dummy object following the line.
my only real problem though, is making the object invisible. i need to make it visible and invisible. not the path, but the object.
could you explain, please, how do to that?
thanks
