    Hi,
    We’re planning to use Vuforia, for one our clients, and we’ve got couple of questions we could use your help.

    I will first explain our use-case:

    We’re using Unity to build this app.
    • User visits a car-showroom
    • User scans a car (a real life car model), that’s physically present in the showroom.
    • We will detect the model of the car and overlay it with hotspots that the user can click on interact with.
    • For step 3 above we are planning to use Model Targets. (https://library.vuforia.com/objects/model-targets)

    Now here comes a blocker:
    We’re able to successfully use Model Targets, and detect the car model, as long as we have the model target pre-embedded / pre-included in our mobile app build (generated from Unity). 

What we want to do though is download the model target from the cloud, so there would be multiple model targets in the cloud, and once the user downloads & installs the app, we want to dynamically download all the available model targets from the cloud. 

Can you please provide some assistance, or link to documentation on how we can achieve this above bit. This is very important for us to achieve, as there can be dozens of car models, and pre-embedding them is not feasible. It’s not feasible due to two reasons, as that would balloon up the app size, and furthermore car models are bound to update, so if we hard-code that data, then we will need to update & submit the apps to stores, every few weeks.
