So, I'm starting with my gantry and I've encountered this first problem: one of the two socket is stuck on the terrain.... Anyone have a solution?
Ok, I've found how to solve, put there the solution for another that encountered the same problem: When you create your support arm, they will be set with the wire support at 0 because the BP, when you build it in the editor, automatically take the height of the wire from the ground level, to the upper anchor point. Obviously, later you have to create the gantry system with the support arm at the right height by setting it with the mesh of the masts. If will be more helpful for other, I can show how I do it with images
