PCP floor tiles acting as path tile.

So this is my suggested solution to allowing buildings with interiors without having to change how you design buildings to fit the path system that wasn't made for interiors.

Basically, it's a roof tile that is a floor tile, that acts as a special piece that if up against a path, guests can walk onto it. When scenery items get guest AI collisions so guests can't clip through walls on paths, this would be a perfect solution to interior shops, restaurants, and the likes. Then there could be special tiles, like checkered tiles, hardwood floors, etc.

This is the reason for my invisible path thread, I think it would be much easier to make a transparent skin for the path than to make scenery objects allow peeps onto them like you suggest. Build your floor however you like then use the invisible path to direct the peeps where you want.
