Alien Isolation [Mother VR] is the best VR experience I've had and it's a free mod.

Got this working, but it was indeed a big faff, but not because of the shader setup, no, because the MotherVR mod that you need as well as the GrandMuthr mod doesn't work on windows 11, as for some reason it expects the game to be under an "AlienIsolation" folder and not the default "Alien Isolation" folder that steam puts it in.

The fix is to quit steam, edit the appmanifest_214490.acf file to change the game folder to "AlienIsolation" and rename the actual game folder to the same, then restart Steam. Phew. Now it works.

It is a HUGE improvement over the MotherVR mod. A whole new level of immersion and it looks so much sharper, with way less aliasing. Those androids are still the most annoying thing about the game though!

The appmanifest edit did not work for me, I had to make a symbolic link before it would launch.

That's probably a more elegant solution.

That sounds like an easier way to sort the Windows 11 problem if it works, nice one. Can't believe that we have to do this ****.

I've posted this before but in case anyone wants to use the symbolic link fix mentioned above these are my own notes and how I did it...

1. Go to Steam\SteamApps\common and move (cut & paste) the "Alien Isolation" folder to somewhere outside of Steam.
   I went with G:\Games as that's the same drive I have Steam on.
2. Rename the "Alien Isolation" folder to "AlienIsolation" (no spaces!)
3. Delete the Steam\SteamApps\common\Alien Isolation folder if it still exists
4. Open a cmd command prompt as Admin and enter this principle:
   
   mklink /d "Path To Steam Alien Isolation Folder" "Path To New Location"
   
   i.e. for me it's SPECIFICALLY: mklink /d "G:\Games\Steam\SteamApps\common\Alien Isolation" "G:\Games\AlienIsolation"

This creates a "SYMBOLIC LINK" between the 2 directories. From Steam's point of view, the game is still installed in "...Steam\SteamApps\common\Alien Isolation" because Steam requires it to be at that path to launch the game.
