This is the closest solution. I figured it out after 4 hours of trying. Unfortunately, the result is not the same as the mentor (Epic Games) is teaching me. He simply drags & drops the Actor_Weapon_Select in the world and is able to change the weapon’s appearance by selecting Weapon Type from the drop-down menu in the details tap but I am not able to do this and had to come up with a solution which, in my case, as you can see in the video below, I am changing each SkeletalMesh after duplicating them. I do not know if my solution is going to affect my end exam submission, but spending almost 4 hours is too much, which is why I am moving on with my studies. Please let me know if you have a better solution to this issue and thanks.
