the hidden underground world

to my great irritation and dissatisfaction, I've discovered that Lumion in all its glory, is unable to sufficiently render an underground basement level with my current understanding of it. As such, I find myself unable to present an intended secondary element as intended.
Originally, an expanding elevator, able to restructure itself across different floors was planned between the entry point, mezzanine level and the lower Theatre floor. However, as the lower floor is impossible to access on Lumion there is a loss in drama of the elevator as it travels between floors.
