Creating a custom, playable, mesh-deformed creature

  1. What do you want to achieve? Keep it simple and clear!
    I want to be able to play as a creature that is mesh deformed


  2. What is the issue? Include screenshots / videos if possible!
    I don’t know how to replace the base character with the creature when i click a button for example. I’ve searched a lot and I can’t find a base script or any requirements for it to work, i can’t play as the creature itself (like i just know that the group should have a primarypart).

If you could put me in the right direction it would really help! thanks!
