Ok so the first step is having Content Manager of course
Open Up the folder of the "Problematic" car by clicking "Folder" in the Content manager car screen
copy the full name of the cars folder like (ac_legends_porsche_917k for example)
now navigate to:
Program Files (x86)\Steam\steamapps\common\assettocorsa\extension\config\cars\loaded and create a new txt file which you name after the cars name (ac_legends_porsche_917k for example)
and change the ending of the .txt file to .ini and click ok.
Now open the .ini file which you created and paste in this command:
[SHADER_REPLACEMENT_...] |
MESHES =
IS_TRANSPARENT = 1 |
Now to find out what the name of the "Mesh" is which is bugged open up the Car in the CM showroom and click on the cars windows (the selection works in a layer so one click selects the surface and another one the object behind it)
Next thing is to go on the side panel... you will see "Name:" followed by the name of the mesh and the 3 dots for options. Click on the 3 dots and copy the name under "Mesh Object".
now copy this name into the .ini file and add it to meshes. Sometimes you will need to add multiple meshes just seperate them with a comma and a space.
usually you can see which glasspanel you chose by the words:
EXT (for exterior) or INT (for interior)
Save your .ini file and open the car on a track and it should have clear glass
what we did was overwriting the shaders for glass when the car is loaded in the gameworld and made the glass clear no matter the shader.
