I have two objects (mesh): the first one is a grid that represents the elevation of the terrain and the second is a polygon that represents the river. What I'd like to do to is to displacing (and warp) perfectly the polygon of the river on the mesh of terrain.
I have been trying to add the Shrinkwrap to the river polygon but the result isn't what I was expecting: in some portions the river is on the terrain but in some else it's below. It's like the river's polygon it's positioned on a fixed altitude without following the terrain.
Do you have any suggestions to do it correctly and displace the river on the terrain?
Thanks in advance, Giulio
