The bsp program (sxqbsp3.exe) is a merge of code mods to the original
Sin qbsp3 by David Hyde on the one hand (gensurf support and assorted
bug fixes), and Tim Smith & Armin Rigo on the other (Quark enhanced
texture positiong).  It hasn't been extensive tested, so any problems
should be notified to:

 tiglari@hexenworld.com

The original Sin qbsp3 seems to handle texture-positioning better than
than Q2 qbsp3 does, and David Hyde's build of qbsp
(www.planetquake.com/gensurf) uses floating point coordinates, so if
something goes spectacularly wrong with this, you can try either of
those and see if it's better.

But whatever you do, *DO NOT* pester Ritual Entertainmen about any
problems with sxqbsp3!


The qvis3.exe and qrad3.exe programs are the regular ones in the
`Retail Sin Utilities', available from www.ritualistic.com.  
You should get this .zip, since it contains many other useful programs.
