May I ask which Wikitude SDK product you have been using? In general, you can work with 3D models and Tracking maps even if you are using a trial version of our products so it could be that there is somenthing wrong in your code. Have you tried our samples to see if this works for you?

So currently I'm still using the free trial. I have been played with several 2D features (scanning, tracking) of wikitude. However, when I tried to load some more complicated features like 3D tracking, 3D marker and 3D model at geolocation, I couldn't get anything in my screen. Does that means I can't use those feature with free trial?
