I have successfully cooked one map for ps3. It was WAR-UNK-MT_OLYMPUS. After i cooked this map I wanted make a few changes to a map that Nootsac & Duragesic already cooked WAR-UNK-HALL_OF_GIANTS such as weapons locker contents and so on. MY rig is a Dell XPS 420 with the Q9450 processor with 4gbs of ram and the nividia8800gt with Vista Ultimate. He has a older rig but still capable of executing cooks for the maps we have so far except WAR-UNK-MT_OLYMPUS. This is the process I have used: Ok made the edits saved in C:\Program Files\Unreal Tournament 3\UTGame\CookedPC\Maps/WAR-UNK-HALL_OF_GIANTS.ut3. I than opened the Ut3 frontend pressed browse to find map in c: pressed edit map editor opens entered save as to overwrite to C:\Program Files\Unreal Tournament 3\UTGame\CookedPC\WAR-UNK-HALL_OF_GIANTS.ut3. Ok then I close the editor and input mp name/ change PC to PS3 then press cook tab leave language to int. select map as mod type press cook, then type map name when prompted press ok. Now the map begins to cook for a while and then at the same point I'm getting a windows message that says " ut3.exe has stopped working" and windows asked to shut it down. And the map does not cook. I have attached a snip jepeg to show where the cook stops. I hope this can help to get some answers. By helping me you would be helping the whole UT3/PS3 community as my clan has been making strides to improve the availitbility of custom content for the PS3.
