Rendering issue here that I have seen on multiple projects now. When I move too far from the origin of the level (current project tests at about 12000 quants), everything disappears from view.

Turning the camera to some angles causes the level to reappear, but everything (with the exception of skybox) vanishes otherwise, sometimes flicking on and off as I pan the camera around. Debug panel confirms the entities stop rendering.

What on earth is causing this? The level is script generated with no BSP tree information. Level models include static objects with no action, and objects with a simple init action that otherwise do nothing. Am I missing some sort of "max level size" variable I should be setting?

Edit: To further complicate, it only seems to happen when I go too far along the positive Y axis. I can run in any other direction all I want without anything disappearing. Level surface is a tile of randomly-chosen slab models.
