o.k. i try it otherways: for example: i would like to build a city. houses, skygrabbers, streets cars and so on. i would like to fly through the streets of this city. Now the problems happen: when i rise the camera, the camera sees the horizon, so i could cover this with terrains but this slows down the computer. it would even be nice to have the sea along the horizon and on the other side something like a light forrest. later in the movie it could be possible to fly over this forrest... second problem: in would kind of measure would anybody recommend? i worked with a measure of 1:10 (1m = 0,1m)because the camera does not see the things right when i really use real measures. or are there camera settings that are to prefer? so if anybody tries out this kind of movie, please tell me, what kind of tricks you use to make it "real"... thanks a lot benjamino
