28. Fix Normals (if needed)
- 3D View menu >> Mesh >> Normals >> Recalculate Inside
Note:
- You can select each mesh face with Normals facing down and flip them individually
- For this tutorial, I am selecting all of the faces and using Recalculate Inside to fix the Normals
29. Track outline
- While this tutorial uses the simplest possible shape for the track, the same steps are used for any shape. The outline of a tunnel. The outline of a bridge. The outline of a road with stone walls. Etc.
