This software has been optimized for Pentium, WIN32S systems. I should work with Win95 and WinNT.
 
This version of QBSP, written by code god John Carmack, has been modified to help with duplicate plane and point off plane errors. In this modification, QBSP returns the plane data in which it had a problem with.
Example:

WARNING: brush with duplicate plane
Plane data:
Point #0: 993, -817, 274
Point #1: 971, -817, 292
Point #2: 976, -817, 296

POP ERROR: plane data: 648 -803 -96
POP ERROR: plane data: 648 -820 -96
POP ERROR: plane data: 551 -820 16
POP ERROR: plane data: 551 -803 16
************ ERROR ************
CheckFace: point off plane

You should be able to find the plane information in your .map file.

If you are used to going to the DOS prompt to compile your bsp, I would strongly suggest using a shell to capture the output. I use PFE (Programmer's File Editor). With PFE I can execute a dos command (eg. qbsp -verbose mymap) and capture the the entire output. Watching the 'WARNING: brush with duplicate plane' errors flying by the screen doesn't make me feel very good when I use a DOS box. I like to know where they are coming from. I think you can find it at www.pfe.com. I don't remember exactly. Just do a search for PFE.

I will be updating this for other errors as I come across them.
