Okay! AWESOME!
So first thing I want you to try:
Yes, have the skeletal mesh under the camera. Then instead of using “Play Anim Montage” use “Play Montage”. It’s better overall, it has a more detailed input/output array. There you should be able to specify the skeletal mesh you want to use instead of “Self.” Pass in your skeletal mesh and let us know how it goes!
Screenshot your work once it’s done if it’s not working, and we’ll make sure it gets there!
