Apply textures to curve faces and align easily



I am trying to create some track pieces in sketch up and then assign textures to them. My trouble is the textures I have made struggle to line up properly.

For flat surfaces I could use the texture, position tool and get it working. This is not possible though for my curve jump pieces. I have tried doing ‘project’ texture from some youtube videos but I get the same problem.

Is there a simple work around for this? I really did not want to have to manually put in the textures / track lines in sketchup.
