Nessa's Oblation Animation Not Working

Reposted due to name correction lol
So I managed to craft the RoN Shotgun the other day, and i noticed that when you inspect it, it shows the animation like on all the other weapons in the raid. However, In game when i pull it out the guns animation refuses to show? I thought it was the shader i was using but when i switched it to its base it looks like plastic. Am i missing something? are my graphics settings affecting it? Help IG?
