Is there a way to find the intersection of objects in a scene? For instance, I am trying to create a contour, or rather, an intersection edge for a terrain and a lake, but there seems to be no way to get to the lake's mesh coordinates, let alone the terrain's. I want to find the intersection between the two that I can then add a thickness to, to make a contour shape mask around land masses in an ocean. If I could apply a Boolean Add to the two meshes, that would work, but again, the Lake node does not allow access to its surface mesh (there are no functions you can connect a Lake object to).
So, so far,...Oh, I can't resist...this problem is..."dead in the water".
