Bastion grille texture issue?

Not sure what mod is causing this, because there's no mods regarding Bastion that would do this. Has anyone else had this issue and resolved it? If so, what mod caused it?

 

I have the same issue, my guess is that it's probably a mod for another modern car, like the ETK cars, maybe Sunburst or Vivace because they could possibly share the grille textures. As I have about 110 mods active, I'm going to disable and reactivate them on the weekend when I have more time. In case I can find which one causes it I'll post it here. Or maybe someone's quicker and found it already out

 

I had the same problem.
Might be caused by a main.materials.json file that automatically got generated?
At least that was the problem for me.

go to: [BeamNG_Documents_folder]\0.24\vehicles\common\
And delete "main.materials.json"

 

Looked for it, but I didn't have that .json in my folder. But after checking for that file I launched Beam, Steam automatically downloaded the new hotfix, after launching, I deactivated two more Vivace mods (Cherrier Emousse and the Ken Block Gymkhana skin) and now my Bastion is fine without any texture issues.
So I'm not sure whether it was fixed by the hotfix or it was the fault of either the two mods mentioned...

 

Greatly appreciate the efforts! I'll have a look with all three mentioned probable causes.

 

Im also having the problem but none of these solutions worked for me. Any other ideas?
