I've got a bridge that, because of the nature of the script I'm using, I need the bridge to be a single object. Everything was fine with it until I added railings to it. Now I don't walk on the bridge, I walk above the railings. I'm using 2 small planes as the physics on the railings, but it seems that once it's uploaded it's creating a bounding box around the entire railing structure and not allowing me to actually walk between the railings. I've tried everything I can think of including using the actual mesh model as the physics layer too, but I still end up walking above the railings. In order to walk between the railings on the bridge deck as you're supposed to, how do I create the mesh physics so it's not problematic as described when I upload it?
