Optimization refers to roombound, multibound, and/or occlusion plane placement for an interior cell.
1. Watch this video for the basics, in case you need a refresher or missed something along the line. "https://www.youtube.com/watch?v=LqzvWVuHh8I"
2.      Things to remember:
 -ensure that snapping is enabled
 -link the roombounds at all necessary points with portals
 -add multibound functionality to objects that need to appear in more than one roombound
3. Too many portals that you can see through in a straight line will cause crazy amounts of lag and/or crash the game; contact the level designer if the issue cannot be fixed by changing around roombounds
- roombounds actually have a light limit of 7; contact the level designer if the issue cannot be fixed by changing around roombounds
4.      Things to avoid:
 -forgetting to link the portals
 -creating too many roombounds
 -creating too many occlusion planes
5.      Please test in-game to ensure that there are no glaring errors or missing objects due to roombound magic.
 - if objects are not appearing when they obviously should, then please contact implementation.
