The concept of "lazy loading for AR.VideoDrawables" is quite similar. Use onEnterFieldOfVision of AR.Trackable2dObject to receive a notification when the target was scanned. You can then use add- and removeCamDrawable to modify the augmentations being displayed/created. I recommend you to implement a basic caching algorithm so you e.g. destroy old videoDrawables only when entering FoV of a new target. That way you can reuse exising assets in case user scans the very same target twice (e.g. because target was lost unintentionally)

Hi, I saw this post here at the forum in which show the code to so lazy loading of images resources and drawables. Very nice but I couldn't figure out how to do it for videoDrawables. I understand, as I have multiple video targets, creating the drawable from inside the onDnterOfFieldFoVision function would be faster because you wouldn't need to load all the videos unnecesseraly
