I am trying to figure out how to make my meshes solid. In other words, so you can't walk through them. The collision tab wont work for what I'm trying to do. I need something like how the mounts and dens are. You aren't able to walk through them and are able to walk on the surface of the mesh.
How am I supposed to do that? Do I need to add something to the .material file?
Edit: ......................... Nvm. I found it. Just check the "Own Collision" button.
