.Map :: MoHAA Mapping

how can I low the size of the .bsp file
now is take 10m

All maps (compiled bsp's, not packaged) that have a reasonable size (not file size but room to run and shoot) have a filesize of 10 Megs or more. By packaging this size is reduced to approx 25% of it's original.

Packaging = zipping as in pk3 = zip
So if your bsp is 10 Megs it will result in a pk3 of approx 2,5 Megs
Does this answer your question ?

As gizmo said, the .pk3 compression system is as goo as you'll get, and 10 mb is really small for a map
