My game is set to Direct3D9. Depending on what your game is set to, you're going to want to try switching it to the other rendering system, which would be OpenGl for me. Here are the codes for each one:
Direct3D9:
Render System=Direct3D9 Rendering Subsystem
OpenGl
Render System=OpenGl Rendering Subsystem
There was one user who had a similar issue, but their textures were all outta whack as well. Turns out they didn't have a driver installed on their computer, or it wasn't installed correctly. Either one of the two- I forget exactly. However what version of windows are you using?
Is it windows 10, or?
