Sponza Scene
============

This example shows how to load the Sponza scene. To run it, you have
to have access to the sponza demo scene, which you can get using::

    git clone https://github.com/KhronosGroup/glTF-Sample-Assets

The current implementation assumes that you cloned that repo
in this directory, or *any* of its parent directories.
