Map textures not showing up in game?

[BlackRidgeWolf]

I was making a map and it had 3 different terrain textures but when I went to test it in game the ground was African_grass. When I went back to map maker it was how it should be but it isn't in game. All my other map's textures show up but not this one... Anyone know why?

Have you tried switching Rendering Subsystems?
Options->Video->Rendering Subsystem.

That worked, thank you!
