Error: MAX_MAPFILE_PLANES

Fix:

Associated with AAS files for Bots or AI. Usually caused by using large numbers of models (with q3map_clipModel in a shader) or large numbers of patch meshes in a map. For Models - removing q3map_clipModel from shader and manually clipping with weaponsclip (or some other clip brush) seems to fix this.

For Patch Meshes - depending on the number of models in a map, converting patch mesh work to ASE models sometimes helps leave clipModel out of shader) to remove the error.

But for AAS problems, ydnar has noted that "BSPC needs to be updated with larger allowable values for planes, brush sides, etc." This affects any Quake3 engine games using Bots or AI. [Kat]

Fix:

You have two choices: cut down on the number of brushes in your map, or don't add bot support. You can try putting clip brushes around heavily detailed brush work, but no guarantees that it will work.
