The Forge tutorial kit. Everything here except fox.glb was drawn or synthesised by util/forgeKit.py in the Singe source tree and is released under CC0: use it in your own games as you like. fox.glb is the Fox from the Khronos glTF sample models, CC-BY 4.0: model by PixelMannen, rigging and animation by tomkranis, glTF conversion by AsoboStudio and scurest. A game that ships it should carry this credit.
