This was a planned addition but it didn't happen for two unfortunate reasons:
1) Rendering a map took forever. I let it run all day rendering FB on a test server and it didn't even finish
2) The resulting file size was beyond ridiculous, somehow out-weighing the actual size of the world it was rendering
The performance hit from rendering and the hard drive hit from the product was just too much for our nimble server so I decided to can the idea. As cool as it is, it just doesn't make sense from a technical standpoint
