The default rendering engine renders objects only up to the distance that's been declared for it in the IDE (Item Definition Entry) file, which can't exceed 300 units. However many objects have a render distance even less than that. Then again, larger objects and buildings have been assigned a LOD (Low Object Detail) model which is streamed from up to 1500 units away. A LOD model is nothing more than a few basic shapes with very crude textures and it is not at all solid, which means you can walk through it (this is a what a lot of player have problems with when they use RemoveBuilding). As soon as the normal building is within its defined rendering distance it will pop into view and the LOD model will dissapear.

So, to sum it up: try to use LOD objects for items that are further way than 300 units.
