Sweet. Looks like we are after the same info haha. Alright, brushes make sense to me, but what about entities and movers? I realize that I could define some unique parameters for those things in ZeroRadiant, save as a map, and attempt to reverse engineer, but I figured it would be more productive to...

I am writing a program to generate quake 3 map files, and I was wondering if there is a document somewhere that details the map file format and how to define brushes, entities, and movers, etc.

Thanks!
