I have a mesh with a subsurf modifier applied that looks a bit like a flat plain with a smooth hill in the middle. What I would like to do is trace a path on this surface (that a characater could walk along for example) by going into the top view, drawing the path in the x-y plane, and then somehow make the path follow the z (height) position of the mesh. That is I’d define the shape of the curve in the x-y plane, but I want the curve to take the meshs z value at each point along the curve.
Is there an easy way to do this? Cheers.
