i know it is a simple question but i dont know how to change it, i have a single terrain with 2000 x 2000 and when im on the corners or in the top of a montain i cant see the other side. it disappear in a way i see the skybox behind it and as i turn my camera different parts disappear, i would like to know what to do in order to be able to se a bigger part of the terrain without this happening, thanks

Go into your player’s camera, and set the far clipping plane to 2000.
