bug: Crashing on Steam with Improved Graphics Mod

[tadpolegaming]

The game now crashes while using the Improved Graphics Mod (https://www.nexusmods.com/alienisolation/mods/19) giving the same hookableOverlayRender error that was occuring on the Epic Games Store port. I actually fixed the crashing by using the 64 bit version of the d3d11.dll rather than the 32 bit one, but Alias is not injecting into the game properly anymore.

Hey! Thanks for checking out the mod.

Is there any chance that you could upload the aliasIsolationCrashDump.dmp file that gets created when the game crashes?

If you're on Windows, it should exist within %temp%, on Proton/Linux it'll be in .steam/steam/steamapps/compatdata/214490/pfx/drive_c/users/steamuser/Temp.

When I get that, it'll let me know what caused the crash. I can't imagine the improved graphics mod would conflict, unless you used the installer they provide and not the XML file?

I did manage to get the old version running by disabling the Steam overlay and running the game exe as administrator. No such luck on this one. aliasIsolationCrashDump.dmp

Hmm, interesting. I'll take a look at the dump file today. I wonder if AIMovieFix (xinput in your game folder) is conflicting with Alias somehow.

Ah I think I see what the issue is... did you extract the mods folder to your Alien: Isolation install folder (same location as file AI.exe)? The mod hit an exception trying to access a critical shader file.

Your Alien: Isolation game directory should look something like this:

Alien: Isolation
  * DATA
  * mods
    * aliasIsolation
      * data
        * shaders
        * textures
  * AI.exe
  * aliasIsolation.asi
  * d3d11.dll

If the mods folder does not exist or contain the expected files included in the release archive, the mod won't work.

It should have shown you an extra pop-up saying:

FATAL ERROR - Failed to find critical data file "C:\Program Files (x86)\Steam\steamapps\common\Alien Isolation\mods\aliasIsolation\data\shaders\mainPost_vs.hlsl"!

That is the section where it "crashed" (it force quits the game and creates a dump file to ensure it stops running in a controlled way).

Could you confirm you have a mods folder in your A:I folder?

[tadpolegaming]

No, I was extracting what was in the mods folder into the game directory. Alias works fine now. Sorry about that.

These things happen, it's alright! Glad you got it sorted out, let me know if there's any more issues, and I can take a look for you.
