Broken Textures [Please Help]

I started working on a map for BeamNG.drive. I didn't really know what I was doing and just messing around with different tools and ended up quitting without saving anything. When I got back into the game there is a texture that shows up really dark when I think it was a lighter rocky texture. I didn't know how to fix it so I deleted the game from within Steam and got it back. The problem was still there. This time I deleted it and then made sure there was nothing left in the folder, deleting the content folder and all, re downloaded the game and that did not work. Then I deleted everything and took the files from a drive backup I had recently made and the textures are still broken. So here's my question: how on earth do I just clear the whole game and make it like I never installed it or screwed up the textures, because deleting everything and redownloading it does not work.

 

Did you delete your BeamNG folder in documents?

 

Sometimes it is the simplest things I forget when trying to fix something.
TV not working? Let's see maybe it's the display or the input, or... maybe it's time to see if it's plugged in.
Thank you for helping me, I was unaware the textures may be on my other drive, and that fixed it.
