While the Interior Tileset is technically a sub-set of the overall Tileset Tool, it is easily equal in complexity to the entire Exterior Set. To create an Interior Tileset an Artist needs to make every 'atomic' piece of geometry that will ever be needed for a given Interior Set, and then use a tool to combine these pieces into every possible configuration they will ever be in. The Artist then needs to check each and every tile generated for errors, and then import all that into The Unreal Engine so that every conceivable configuration a Designer could ever come up with is represented and available.

    Much like the Exterior Tileset, the Interior Tileset can be an extremely powerful tool for Designers, though it requires a serious amount of precision on the part of the Artist creating it.
