Just a recap, just in case...
- Make sure you're also replacing the markings.cfg in the main FH folder and not just putting the markings in themselves. On top of that, make sure that you're putting the mass markings in the 'Markings' folder and not Textures this time around. To access this, go to your main FH Folder > Media > Textures > Markings and copy + Paste everything in there.
- Make sure Feral - Heart isn't running the in background or else you won't see it.
- Make sure you downloaded the correct markings file as well.
- Try changing rendering subsystems and see if that does any good ( best to try all options even though one doesn't seem like it might work ).
- Make sure your computer didn't move files around. Sometimes during updates, the computer likes to move FH files around and such. Make sure it's in your C Drive ( For windows at least ) and everything is where it needs to be.
- If you can provide screenshots if the problem still persists as well as screenshots pertaining where you're putting the things at, that'll be helpful as well.
Hopefully there's a solution to fix this problem o:
