How to Swap body parts of externally loaded gltf model?

[harsh242]

I am trying to create a character customizer like this https://desktophero3d.com/ or https://shrekshao.github.io/gltf-avatar-threejs/
while I have been able to load multiple animations of the model, I am not able to understand how to swap a body part of the model example: changing the head of a model, or changing the outfits of the model.

gltfloader just serves you a black box - a ready-made scene. traditionally if you wanted to change things you had to traverse and mutate it.

in react you should use gltfjsx https://github.com/pmndrs/gltfjsx it creates a virtual graph of the model contents. now you can make stuff conditional.

gltfloader is ❤.
I am just confused about how would I add multiple heads to a model, like will it be a single gltf file with all the multiple heads, legs, and weapon items, etc?
or should I create a gltf file for every character that is possible?
