SOLVED How to fix textures

I have asked permission to use this crash hall on a map, and I can't figure out how to get the outside textures to show. I am very limited in blender knowledge but I do kind of know how to texture. I have tried turning on and off backface culling but it doesn't show up like that in blender here's a pick of beam

I dunno if it’s actually solved, but select all faces that don’t show up on the correct side, and do mesh -> normals -> flip. It’s somewhere in the top left.

 

in beamng there's is a option to do this in the material editor. So if anyone needs this in the future here is the answer
