As the title says, Thrall the unmounted version does not have any animations save for one walking animation. I was making a custom map in the editor and wanted to use the unmounted model version of thrall. “Thrall (Unmounted)” The other Thrall model when he rides the wolf has all the normal animations. Why is this?
Very likely this is a bug caused by something either in the map, or an animation issue with the model. For bugs in WC3:Reforged, you should be able to make a post on the Bug Forums.
