NOTE: AS OF THE MAY 26TH UPDATE TO HALF-LIFE 2, THIS PATCH IS NOW REQUIRED TO RUN SMOD AT ALL.Some of you may remember the
Episode 1 Addon i worked on at one time. While in the end Episode 1 proved to have too many issues to be stable in SMOD, making SMOD just run on its engine proved a much more realistic (and possible) goal.


(Phonged weapons not included)
In short, this tiny patch makes SMOD use the Source SDK Base engine (hence the "215" which is the Appid for it). Which is based off of the Episode 1 engine. This patch also fixes a few of the issues that tend to show up in the campaign when running it on this engine, mainly a few buggy trains. One of the things you should notice in the pics above is that AntiAliasing is now enabled. Usually it is broken in SMOD 40a.
This addon requires that you have the Source SDK Base installed.
The benefits of using the Source SDK Base engine:
-Fixed AntiAliasing. Which is broken in SMOD 40a by default.
-Models compiled with facial expressions with the EP1 engine SDK no longer have problems working in SMOD.
-Phong Shading is now supported.
-A large number of minor updates and improvements.
IMPORTANT INSTALL NOTE: After extracting this archive to your SMOD folder, YOU MUST RESTART STEAM! Otherwise it will not apply the modified gameinfo.txt file which now loads the Source SDK Base.!!! IT IS NOT RECOMMENDED THAT YOU INSTALL THIS INTO SMOD REDUX, SMOD TACTICAL, CSS SCI FI, OR ANY OTHER SMOD-MOD. THEY TEND TO MAKE A MASSIVE AMOUNT OF CHANGES THAT CAN STRONGLY AFFECT COMPATIBILITY WITH THE NEW ENGINE. THIS IS FOR SMOD 40a ONLY. !!!DOWNLOAD HERE
