Roblox has uploaded an Emote we are giving away and I am attempting to play this animation on an npc in order to display it for previewing in a viewport. When attempting to load the animation I receive this error.
Typically this is indicative of the group not owning the Animation, but I would assume this would not be the case for animations uploaded by Roblox themselves.
This issue can be reproduced by attempting to load an Animation with the Id 18526410572 onto a rig (Tested with R15) in a viewport frame. The issue should also theoretically happen outside a viewport.
18526410572 is the “Animation” Instance that refers to the AnimationClip. The AnimationClip associated with this Instance has the following assetId = 18526397037.
