Sink walls to specified height when near my character

Hey, so I want walls that my character walks behind to sink down into the ground so that I can see my character again (instead of making the walls invisible). So far, I’ve got a Socket on each mesh that I want to sink down called Sink, and that is where the mesh should sink down to, so that the top of the mesh is still visible. Next, I have a tag on each mesh/BP defining it as a Wall, so that only wall tagged meshes will sink down. All of that is working… except for the part where it only affects things that have the wall tag on them, because it sometimes likes to affect other meshes, including my player object, and what it decides it is ‘overlapping’ is kind of random…

Anyway, I have more details to the question, including screenshots of my BPs, in my forum post linked below. I would have put the whole question here but I can’t fully describe my problem without having all those screenshots. Please, if you can help, either answer here or in my forum post.
