Quad wall shadow gaps

[lament saffron]

I don't know whether to put this in #🛠️┃probuilder or here so I'm just posting it here. So I made a basic room with Probuilder that uses walls that are basically quads, and when I use realtime shadows or shadowmasks, the walls have this gap in the shadows that's been really bugging me. I've been trying to find a solution for quite a bit now and I have no idea what to do.

This is something that is expected with realtime shadows and thin walls.
The easiest solution is to add thickness to your walls.
