Rendering a polygon layer

[mz12345]

I have a layer of geometry type polygon that I wish to display in Unity. I read something about the even-odd fill rule but Im not sure how to create a triangulation based on that alone. 

I've tried to make it work using ArcGISGeometry.FromJSON():

However that throws the following error:

Im simply passing the downloadHandler.text as the json, so maybe it needs some additional processing before going in. The source of the data is a feature layer.

I am also wondering if there is a way to visualize a polygon created by ArcGISPolygonBuilder. Have you figured out a solution yet?
