There is a piece in H5 blocks that has missing collision on one of it's faces. It may be a detailed primitive, or a wall/floor piece. I believe it's somewhat large but only 4-8 deep at the most. I looked for it for a little and wasn't able to find it, does anyone have an idea which piece this is? I need it for a very specific situation where your feet will go through the object but it maintains the ability to add textures and matte settings.
