Hi @ManFromNeptune,
Yeah i'd like to attempt a 3d version at some point, not sure when i'll have time to though. In the meantime, the original auther has published a 3d version of the tiled model at https://bitbucket.org/mxgmn/basic3dwfc/src/master/
Now that Unity uses a modern version of C# it should be easier to get it running inside a Unity project
