*Note: I created the most of the tutorials using the Roboblitz and Gears of War editors. Based on the engine, and the version, some properties specified may be in slightly different locations than what is displayed in the screenshots.

If you need to learn how to create a basic map I would reccomend:
For UT99, UT2K3 & UT2K4: the Unreal Wiki.
For UT3: Waylon's Tutorials.



Level - Stream Multiple Levels





Stream Multiple Levels is used to 'stream' or load and unload multiple individual levels out of a 'master' or 'persistent' map.

This action is used when smaller sublevels are contained within a larger persistent level. Imagine a large open terrain with smaller quadrants that are filled with meshes or BSP or whatever else. The terrain would be in the 'persistent' level. But each quadrant would be its own individual level, but contained within the terrain level. Depending on where the player roams, you can use the 'stream multiple levels' action to load multiple sublevels - other quadrants - before the player gets to them, and unload others that the player isn't near anymore. This way, level content is always active near the player, but not sitting around uselessly when they player can no longer interact with or see it.

• Load will cause the designated maps to load.

• Unload will cause the designated maps to unload.



• bMakeVisibileAfterLoad will allow the level's contents to be visbile immediately after being loaded if checked. If unchecked, the level will load, but will not be visible until a 'change level visbility' action is applied to the particular level.

• bShouldBlockOnLoad (I think) will block players from entering the level area until the level is fully loaded if checked off.

• The levels are commonly assigned by adding level slots via the green ball, and then typing in the level name under 'LevelName'.
