Has anybody experimented with designing interiors of buildings? I've been able to make some nice exteriors and roadways in the Korhal terrain set, but haven't really thought of anything for making interiors of say buildings that you could "enter". Would be cool for my map.

That looks pretty neat! Downloading now...

On Templar Hero Arena they made a doodad that was the factory building that could be gone inside of.
