I have a jk2 map my friend made how do I get it to work with JA?
Put the pk3 into your base folder.
You need to convert the map to use the BSP format that JA uses or else it won't load.
Re-compile the map using the "-game ja" switch in Q3Map.
You may also need to re-do some entities, scripting, shaders, and textures in order for it do work right in Jedi Academy.
My server is running the JK2 map packs downloaded off of pcgamemods.com a lot now. Feel free to join anytime (IP in signature) ; )
