Xamarin Forms UrhoSharp - How to set up the Assets Folder

Hey guys ,

I'm trying to use a folder in a XF - Urho Application but its not working .

UrhoSurface.Show<UrhoApp>(new ApplicationOptions("Data"));

var cache = ResourceCache;

planeObject.Model = cache.GetModel("Models/Plane.mdl");

In my Droid Assets , i created the Folder "Data" and added the Models etc...

Am i missing something ?
