As you mention in this thread - https://support.wikitude.com/a/forums/topics/5000094545 - that the setup is working for you now, I wanted to check if also this question is resolved?
In general we don't offer any additional sample app than the one we inlclude in the SDK download package. This should give you the details needed for loading the .wtc file, also in combination with the technical documentation.
Thx and greetings
Please I'm lost.
