I already answered your question via email. Here are the details again:
If you work with Studio and want to make use of the rendering done by the Wikitude SDK you?ll either need to work with the JS API or with one of our Extensions (Titanium, Cordova, Xamarin). The Native API does not offer Studio support. Furthermore you?ll need to take care of the rendering on your end, so I strongly suggest to have a look at the JS API.
