unity. Should the weapon be painted on to the animation immediately or can it be substituted into unity?

Question

Unity

In general, in the project there is a character with a weapon that he can change and there are quite a lot of these weapons + with each different fighting style, but there are also weapons of the same type, do you need to paint weapons on the sprites themselves or can you substitute the weapon sprites in the unity itself?

Answer 1

Draw separately. And then, in Unity, you substitute a weapon for the character.
