What's the difference between "CharacterWorldHeight" and "WorldScale"
The first one is used to define the offset (in world units) of the character healthbar and (other UI stuff we displaying over the character, for example - player nickname in case of PlayerCharacter).
The world scale is the world scale and affects both visual (skeleton) scale and 2D physical world character's appearance.
So if I change the world scale, the skeleton scales as well?
Yes, the world scale is for both physics and visuals (skeleton). They should be scaled simultaneously anyway as otherwise physics will not match the visuals.
Yeah I got it sussed, there's a pic under servers on discord
