I really wanted to use Q009's SauerEnhanced-Mod together with the svn of Sauer.
Since SauerEnhanced is a source mod, I had to combine the sources of Sauer svn and SauerEnhanced svn to reach this goal.
And since this was a lot of work i decided to post this here with the permission of Q009.

If sometimes sound will not be played that probably means game is trying to play too much sounds at once. Try "/maxsoundsatonce 10" or higher value.

Source code is included. Check "SauerEnhanced/src".

--INSTALLATION--
Download the mod-file at mediafire, URL is on the bottom of the post
Just move everything from "sauerenhancedsvn-v2-.zip" to main Sauerbraten directory.
You do need Sauerbraten svn revision 2545 or higher to use this mod.
If you are using Mac or Linux, you will have to find a way to create a compileable project file for this yourself.

--USAGE--
To run it just execute "SauerEnhanced.bat"

--KNOWN BUGS--
v.2.:The experimental GLSL support is causing the Hudgun to flicker if GLSL rendering is activated.
note that GLSL support in Sauer is still buggy and experimental.
v.1.:When you are in Editmode and select something and then turn away, your console will be spammed with "selection not in view".
-fixed in version 2.
