I did manage to figure out where to place the teleporters for the walking poses (half a grid square away is my recommendation hold down the ALT button to move it freely), but it wasn’t a one-and-done kind of deal. It just sort of merged my two Sims together.
Unlike most custom poses meant for couples or groups, placing two teleporters in the exact same space didn’t work. The poses in this set were sorta tough to figure out.
