Hi, I have a large object from gta:sa, it is a single terrain object and when ever I look around, mainly away from it's origin point, it disappears. There is no zones yet, and LOD is 0 (highest will only be used). Is there something I am missing? Any help is appreciated.

I had the same problem with large models and each time something different fixed it.

Make sure the model is above 0,0,0 before exporting from Maya or blender.
Or
Split the model into seperate pieces in maya.
Or
Shrink it in maya. Re-Import to codwaw. Use model scale kvp in radiant.
