Unfortunately, the engine update for HL2:EP2 broke Substance and many old mods. But we're investigating the possibility of resurrecting it through different means, expect developments in the near future.

Since I've recently built a new machine, I'd be super excited to play through this mod again with the beauty of the current Source engine. :D

I found out how to fix the ai disabled bug:
1. Open autoexec.cfg with notepad in C:\Program Files (x86)\Steam\SteamApps\sourcemods
2. At the bottom of the text, make a new line and add
ai_norebuildgraph 1
3. Finally, save the file.

Made a mistake, the path is actually C:\Program Files (x86)\Steam\SteamApps\sourcemods\HL2Substance\cfg

You can still fix it by mounting it into SMOD Standalone. You can get it at bsnooch.com

Hope this helps :)
