Make sure it starts and ends outside the bounds of the mesh surface. Adjust the ‘Count’ slider to have as few points as possible but as many as necessary to follow the road accurately. The ‘raise path’ slider will raise the projected points above the mesh surface, which can be helpful in reaching a “state of equilibrium” where …
