it would be great if this can be export as a unity scene
If only I knew anything about unity :)
Basically, if it can export to any standard 3D format - .obj, .fbx or whatever - then Unity will be able to import it.
Export to some 3D format is on my todo list for MFCG, but its priority is pretty low, to be honest. I'm going to remake Toy Town at some point in the future (maybe as a part of MFCG) - then I'll get back to this.
