I need to load Model targets (The .unitypackages from Model target Generator) dynamically from an url. I found this documentation https://library.vuforia.com/articles/Solution/how-to-create-and-load-targets-in-unity.html#image-target-loading but it seems to be outdated. In the picture below you may see that ObjectTracker and several others are not recognized. I am using Vuforia 10.2.5 .
Since I am new in programming with C# and Unity, I would appreciate your help. Thanks!
