When you download VAR file, there are usually some additional files you have to download with it. There are 2 ways of doing it:
1. After downloading your VAR file and putting it into VAM/AddonPackages folder, launch your VAM, click on "HUB BROWSE" button in the main menu, and then click "Scan Hub for Missing Referenced Packages". It should find missing dependencies and it will allow you to download it. After downloading it, I always relaunch VAM, because VARs containing morpgs are only scanned during the launch.
2. Sometimes dependency files are not available on the hub (you will see the red Not On The Hub info). You will have to look for them on the site you downloaded your VAR from. It is the case if the scene/look is behing a paywall, meaning it was not free.
