hey i was wandering if there was an "easy way" to convert a map without having too many bugs, from JA to JK2, 
 i tried opening the map file in gtk jk2 and my for some reason got somehow move a bit, some brushes where out of places, there where all these errors etc that dont exist in ja. ..
  
 
  
  
    Ungroup remove all of the entities except lights. I would also ungroup things like func_doors and redo those. Then I would texture all brushes that are covered in a texture JO doesn't have in something like system/caulk.
 
 Then you should have no problem. Ja has features that JO doesn't have so some things will have t change/be removed.
  
 
  
  
    doesnt the latest q3map2 come with a converter?
  
 
  
  
    nm, it came out a couple versions ago, im betting it might work for jk2 to ja :o then again maybe not, i havent tried it yet.
