Definitely a must have, but I can't .craft to load. Failing custom craft, I installed stock craft from stock game 1.04 using only stock parts and still can't get a craft to load. Help please tried with blender 2.65, 2.69, 2.73, o 2.75a (32 and 64 bit versions) same errors. last error listed tried importing stock craft only - blender generates error: Traceback (most recent call last): File "C:\users\username\desktop\blender-2.73-windows32\2.73\scripts\addons\io_kspblender-master\_init_.py", line 59, in execute return import_craft.import_craft)self,context,**keywords) File "C:\users\username\desktop\blender-2.73-windows32\2.73\scripts\addons\io_kspblender-master\import_craft.py", line 63, in import_craft craft = import_parts(filepath,partdir,rightscale,right_location File "C:\users\username\desktop\blender-2.73-windows32\2.73\scripts\addons\io_kspblender-master\import_craft.py", line 107, in import_parts if os.path.isfile(partdir[part.partName][0]): #make sure the part file exists so nothing crashes keyError: 'probeCoreOcto' location: <unknown location>:-1 key error is always the command pod then crashes. any help would be appreciated, thanks - - - Updated - - - experimented. I placed the blender directory in steam apps\common\kerbal space program then I launched KSP, created a new sandbox game, loaded Kerbal2 craft (stock craft - no mods installed, stock/base game) I verified all parts, then launched craft. With ksp in background, I opened blender then the kerbal 2 craft file (stock) - same error io_kspblender-master - is installed io_object_mu-master - is installed kspdir.txt - c:\Games\SteamApps\common\Kerbal Space Program (correct, thats the game location) hope this helps. thanks
