Unity environments to maya

Hi there,

Sorry if this sounds like a dumb question but I was wondering if there was any chance of importing environments made in unity and exporting them out into other software such as maya or houdini?

I am currently working on an outdoor scene and would like to incorpare unity's level design in order to create an environment using quixel models which I can then lookdev/light in maya.

I've seen a lot of post of importing but none that say whether exporting levels is possible.
