Entity Model Layer Not Synced With Animations

As the title suggests, I have an entity with two texture layers, a base layer and another layer that glows. In-game only the base layer moves with the animations while the glow layer does not. I have seen a couple threads of people asking this question but no one has gotten a response that says HOW to fix the problem. So now I'm here asking the same question hoping to get a helpful response. Thanks for your time :)
