A chunk of the time for the art has been working through getting the 3D art to appear well. There is a mild disconnection in the web 3D engine's documentation for a Blender exporter, and its actual behaviour in the loading moment in the javascript code. Also not to mention there are three versions of the exporter. When finally working, there is an extra issue of ensuring the particularly easily workable assets in javascript. There is an awkward undocumented assumption in the 3D engine and exporter of the nature of content being brought in from blender. So. All this to say, the 3D models exist and will be added sometime this week!
