Bug Exterior Models Not Showing

The Bug

This is bug you will encounter if you are following the Lokir's Tomb tutorial, specifically this step. You will also encounter this anytime you place a large static in an exterior cell, such as a farm house, or ship. When you place the pieces in the editor, they will show just fine, like this:

But when you get into game, this is what you'll probably see:

Solution

You need to open the preferences on the static and mark it as Full LOD. This is a work-around, as having to many objects flagged as Full LOD in an area can severely impact performance.

Notes

Oddly enough, I had to add in a new static to show off the bug. I had already marked my tower as Full LOD, and toggling it off didn't cause the bug to happen again. More testing required!
