[1.4.0] Launching with +set fs_basepath parameter results in GLSL error

[BugFixesAndPerformanceImprovements]

Describe the bug
When setting the basedir to where Doom 3 BFG Edition is installed (ie. through Steam) with +set fs_basepath it results in the following error: ERROR: While linking GLSL program 0 with vertexShader gui and fragmentShader gui

Looking at the log file it seems DOOM BFA is not looking within its own base install/extracted path and only at the Save Game user folder for all the required files and the path provided by +set fs_basepath as evident by this section from the log:

Current search path:
C:\Users\<username>\Saved Games\id Software\DOOM BFA/base_BFG
C:\Games\Steam\steamapps\common\DOOM 3 BFG Edition/base_BFG
C:\Users\<username>\Saved Games\id Software\DOOM BFA/base
C:\Games\Steam\steamapps\common\DOOM 3 BFG Edition/base

To Reproduce
Steps to reproduce the behavior:

1. Have DOOM BFA in its own folder, eg. C:\Games\Doom 3\sourceports\DOOM BFA
2. Have DOOM 3 BFG Edition installed through Steam, eg. C:\Games\Steam\steamapps\common\DOOM 3 BFG Edition
3. Run DOOM BFA with the +set fs_basepath launch parameter pointing to where Doom 3 BFG Edition is installed through Steam, ie. C:\Games\Doom 3\sourceports\DOOM_BFA_1.4.0-win_x64\DoomBFA.exe" +set fs_basepath "C:\Games\Steam\steamapps\common\DOOM 3 BFG Edition
4. DOOM BFA crashes with the following error: ERROR: While linking GLSL program 0 with vertexShader gui and fragmentShader gui (see the full log at the bottom)

Expected behavior
DOOM BFA should run normally with the basedir provided with the +set fs_basepath runtime parameter without having to copy and paste all Doom 3 BFG Edition files for each Doom 3 source port out there, eg. DOOM BFA, RBDOOM 3 BFG, etc.

dhewm3 for instance works fine pointing it to the regular non-BFG version of Doom 3's install directory.

Hi there, this is by design. DOOM BFA for Windows is meant to be used as a portable executable that you install in the game files. Of course there is the cmake argument PACKAGED that add a new search path that covers the need you have, but that is meant to be used on versions of DOOM BFA where there is no option for the player to install the source port into the game's folder (for example check the Flatpak release). One workaround to the issue you have would be to put the files of the source port into it's own save folder.

[BugFixesAndPerformanceImprovements]

Hi MadDeCoDeR, thanks for responding.

Couldn't you just make it look at its own base folder/path where the executable is run from by default?

As a way of keeping your Steam data and the sourceport's files clean and separate.
