[2019] A few of you requested this, so I threw my models into Unity to see what happens. What do you think about amateur Voxel Factorio?

Unfortunately the save file format is really cryptic, IIRC many parts of it are just memory dumps. You could do that with blueprints, but they don't preserve everything (such as items on belts or flying bots). But there may be a way to write a mod that would export the data to a more structured file that the renderer could read.
