Feng Yun 2D-3D Samples

The problem with this format is that

1: the "build" file specifies which meshes and which "shader" file it uses
2: the "shader" file specifies materials

Except neither of these have extensions.

I mean I guess you could modify the script to manually add some dummy extensions...
