Then make a small scene, e.g. cube on plane w/ simple textures (only one color) a camera and a light. Export this and see what happens. If you get the same strange result, post the file.
Or try geocities/tripod/yahoo… to put up the file.
I don’t know how Amapi exports, but only the main file is needed, no mesh definitions. Maybe you can shorten your file??
How big is your original file?
BTW: the povray 3.5 documentation says that there is no limit for the cameraangle, but values > 360° will give you repeating images. An angle of 180 is like a fisheye. Dunno if this is correct for pov3.1, but it might be.
