I am new to the threejs. how can I change/update the material of any 3D model, if all Materials are given in the object. Like there are different hairstyle of the object, by clicking on any hairstyle, that hairstyle will apply to the object. sorry for non-code question, actually I don't have any source link to follow that's why I don't have any code yet. It will be grateful if you provide me any source for practice or tips. I followed how-to-build-a-color-customizer-app-for-a-3d-model-with-three-js for changing color of the material, but I don't know how to change the material.
