objects just fall of at the end of a plane

I have a scene with a lot of objects like buildings and stuff on a plane, but it seems that the more objects I put on the plane (ground) and I angle the camera a far away distance to see most of the city, some of the buildings towards the end of the plane seem to drop off at the end…is it because I do not have enough memory…I have 16 gigs of ram, or is it the camera fault? please help.

Sounds like a clipping problem. In the viewport on the [N] panel under ‘View,’ there’s an option for clipping start and ending. Increase the end value accordingly and it should resolve the issue.

will try that…thanks

Mind you, though, that the camera clipping is controlled independently from the viewport clipping:
