Wanderer not at my PC so I cant check for you but the best way would be to add more character meshs for the same BP_Player_Character. In the Game Instance is where set up your characters. Just replace with the mesh you want to use. There is Bob Blueprint and Plate there as default but I believe you can just add more in the Game Instance. There is a video how to add characters on the first page of this forum post or on Allars youtube. If you wanted different Player Characters for various reasons you would want to make a child BP off the BP_Player_Character and customize their actions. Then for whatever Game Mode you would set which Player Character to use. Hope that makes sense but I believe thats how its done.
