Map Filesize

The average filesize of maps has rocketed since the release of UT2003.

Some tips for reducing the size of your map:

• set all unseen [BSP surface]?s to unlit (those completely behind static meshes or terrain)
• set bsp surfaces where shadow detail is not needed to 256
• rebuilding lighting with DXT1 compression
• compress all (custom) textures that don't need an alpha channel to DXT1
