I have 2 terrain entities created , each is 128 by 128 vertices with 256 size for each terrain cell .

the first terrain is centered at 0,0,0 .
the second terrain is centered at 0,0+first_terrain.max_y*2,0

both use the same material and textures/skins .

the second terrain is wholly clipped away at certain angles by the engine , even when I am directly on top of it ,while the first terrain remains visible .

why would my second terrain clip away completely even though my camera is right on top or near it ?

Thanks.
