So far using UE4, I know how to attach, fire, and drop weapons. Even change the equipped weapon, but not more than 2. I want to create a simple system like Megaman SNES, you have actually one weapon and you change the effect and color. I belive that I have to create a list of effects or a simples system to make that, but I can’t figure out how. Can you help me? I’m brazilian and don’t speak English very well. If you know some tutorial similar to this, please show, me! 
Thanks a milion.
