can any1 help me here please?
id be much appreciated, thankyou
select the perspective camera in the outliner then open the attribute editor. Under the Camera Attributes tab change the FarClip Plane settings to a higher number, something like 10,000 should do it. If you have the same problem when your zoomed in too something, change the Near Clip plane number to something lower. 
cheers
sorted!!
