I am new to Wikitude Studio, and am creating my first AR app. I'd like to show and hide multiple models in the scene upon presses of certain buttons. How would I go about this?
The Wikitude Studio Editor is only supporting simple use cases and display of augmentations. It does not support interactivity like hiding / showing of augmentations on a certain action.
As the SDK is of course supporting very complex and interactive use case and scenarios, like you mention, you'd need to work with the SDK solely and implement the AR experience on your end. The best way to start is to check out the sample app which comes with the SDK download package together with the respective documentation section.
Each section includes a set-up guide, which helps you set up your project.
