Is your feature request related to a problem? Please describe (REQUIRED):
I'm trying to change a texture on a model that has several different textures via UV Mapping in the .glb object. But it appears it's not possible as the texture ends up applying to the entire object ignoring the fact that I have multiple materials and textures applied.

or with one material applied multiple times with different textures:

Describe the solution you'd like (REQUIRED):
it would be great to use go.set(model_url, texture_reference, "path to new texture")
And go.set(model_url, material_reference, "path to new material")

Describe alternatives you've considered (REQUIRED):
Currently it was recommended in the forum to use separate meshes to export my object. This is what I'm going to try now, but it's not ideal as they are separate models. And I'm not sure how that will impact the physics and it does make it more complicated vice just using go.set on the model to update the properties.

Additional context (OPTIONAL):
