Noob here. When using the following code, it wraps the image texture around the entire model. Is it possible to apply the image texture to a portion of the model (as opposed to the entire model itself) in RealityKit/ARKit?

CODE:

var material = SimpleMaterial()

material.baseColor = try! .texture(TextureResource.load(named: "image.jpg"))

modelSample?.model?.materials = [material]

If you want to apply a texture to a portion of a AR model, not to an entire model, you have to UV-map this texture to a model in a 3d authoring tool (like 3dsMax, Maya, or Blender). UV-mapping is neither possible in RealityKit 1.0 nor in RealityKit 2.0.
