Once the metadata content is downloaded and accessible via the pointer in the TargetSearchResult, you can use Unity's own runtime classes for getting the 3d object data translated to a GameObject that can be dynamically parented to the Vuforia target. Since metadata could be anything, Vuforia doesn't know how you want to use the data, and so it's up to you to decide how to load it.

Hi,

As per my understanding, the method will only download the model. How to instantiate and load 3D model? Do we need any special loader/parser for that?

Thanks,

BP

If you want to store your 3d models using the Vuforia Cloud Recognition Service, there's an FAQ that explains the details. There's a size limit of 1MB/target for metadata storage such as 3d models.
