Sorry I didn't reply sooner, I was out of town visiting my insane family.
There are only indoor tilesets but they require a pwc file also because the various tiles have lowered and raised areas. Also, as with my mod, you can have walkable placeables, like a stage.
It seems to me that you shouldn't need a .pwc file with the tilesets but then again it seems to me that the fucking game should serve all that information without the client having to download anything. Anyway, hope that helps.
