Describe the bug
When creating a material with only a RGB node (see image bellow), the baseColorFactor is not being exported anymore (working up until 4.2).

To Reproduce
Steps to reproduce the behavior:

  1. Add a material with only RGB node connected to the material output.
  2. Export object to gltf.

Expected behavior
The RGB color should be exported as baseColorFactor in the material.
