Triangle.gltf does not displayed

[cx20]

I tried to display Triangle.gltf with Ashes. However, an error was output to the console and it was not displayed.

Ashes v0.0.16 + Triangle.gltf result:

ashes.main.js:5270 Uncaught (in promise) TypeError: Cannot read property 'map' of undefined
    at Function.<anonymous> (ashes.main.js:5270)
    at Generator.next (<anonymous>)
    at fulfilled (ashes.main.js:860)

I think that it is probably failing to display about models that do not have textures.

Thanks! I'll fix it soon.

I confirmed that Triangle.gltf will be displayed. Ashes v0.0.17 + Triangle.gltf result:
