It would be good to "group" metal mesh and grilles together, and then "attach" an aligned entity to it, so that after the entity aligns itself with the metal, they can move anywhere along the surface of the metal without floating away. Then, when they want to "get off" the metal, they just align to a different surface to resume normal movement. This would simulate climbing across the surface of the metal. I'm specifically thinking about side-scrolling games where the player grabs onto a wall of vines (or whatever the player is allowed to climb) and climbs all over it, up and down, or side-to-side.
It would be slightly disorienting when reaching a corner, and ones perspective suddenly flips, to align with the perpendicular surface, but I'd still like it. And it would be really cool if the alignment could go diagonal with metal wedges.
Edit: In this case, when I use the term "metal", I'm referring to perforated or partial blocks where one would expect an astronaut to be able to grapple and hold onto the surface. An astronaut can't really grip a hull block the way they can grip mesh or grill (or a scaffolding block, when that is implemented.)
