Detailed Description

Defines a switching region for an LOD.

An object will be visible when it is closer than "in" units, but further than "out" units from the camera.

The sense of in vs. out distances is as if the object were coming towards you from far away: it switches "in" at the far distance, and switches "out" at the close distance. Thus, "in" should be larger than "out".
