There's no official export support, but there's a few outside programs to help you. Ninja Ripper will take the frames displayed in the software and export it to blender, which can then be exported to any other 3D rendering software like normal, per workflow. It's obviously not supported, and as for licensing, you aren't given any, so for personal projects or atleast a rough draft, it certainly helps. Just giving a heads up if you created some amazing projects and dont' want it to go to waste.

Also, the developer probably has no rights to transfer his assets to you, for commercialization, but I'm sure you will be able to find alternatives to the ones in this program. And many programs will let you easily replace objects in the scene with another, with a few clicks.
