problem, characters, clothes

first, i’m sorry about my English.
Now, i’m create a game. in game, character can be change clothes, there are many clothes with different 3d models. So i can’t use “renderer.material.mainTexture = yourNewTexture;”. so what should i do?

There is a character configuration project (free) in the Asset store and on the Unity web site, get that and see how it’s done.

"Character Customization " project?
