http://quest-ed.sourceforge.net/dl/index.htmlQuest is an editor for the games Quake and Quake 2, by id software. It also supports other games using their engines, like Hexen 2. Quest was originally written by Chris Carollo and Trey Harrison back in '96, and after they stopped working on it, I (Alexander Malmberg) continued working on it.
IT ALSO SUPPORTS Q3 according to readme and config files.
I'm no modeller and have no clue about quake maps, but wanted to make sure this works, so I edited the quest.cfg file and entered some dirs to where my OA stuff is and exported textures and then it started:
Please tell me if this is at all useful for you, to make OA content and why.
Also I tried searching the forums, but "quest" is part of "request" and "questions" so I found nothing.
