How reused any part of a model blender and Unity?

Hi everyone ,
I’m newbie with blender and Unity3d.
When i’m trying to my own character. I wondered whether there is a way to reuse any part of a model??
Like i could make face/clothes: A,B,C and etc so that i can place it on the humanoid models.
Like that in unity, i could let my users choose their unique appearance.
I can’t get rid of this question.
Could someone give me an advice?
Thanks,
Haruji.

Yes, simply define each of those parts as a separate mesh (all rigged to the same bones). Then in Unity, you can turn the various meshes on and off as needed.

But this is not a newbie-level thing to do… I think you should put this aside until you are more experienced with both Blender and Unity.

Thanks a lot.
Now i could learn anything without anything in mind.
A clear mind.

You could create your clothing for UMA, and then it will handle the swapping of clothes, textures etc. for you. It will generate a model and texture atlas for everything, so you get the best performance also (and the new version is using some new, and very nice textures!).

Here’s a series of videos that show you how to do it all in Blender:
