I placed some small bushes in a location and once I cross the street... they vanish. Is there a way to control this? the point of the bushes is for "cover", but someone across the street will see the person sticking out like a sore thumb.

"In computer graphics, accounting for level of detail involves decreasing the complexity of a 3D object representation as it moves away from the viewer or according other metrics such as object importance, eye-space speed or position. Level of detail techniques increases the efficiency of rendering by decreasing the workload on graphics pipeline stages, usually vertex transformations. The reduced visual quality of the model is often unnoticed because of the small effect on object appearance when distant or moving fast."

You can make new model that only has high lod or increase lod distance by editing xmodel file in hex editor.
