is there a way to automatically create new material into every mesh of a model?
I have this issue with auto-rigging from Mixamo as it removes the existing materials when I download the rigged model. So I have to remake the materials again when importing the auto-rigged model back to Blender.
I don't mind if it assigns only the default Principled BSDF. I just need containers to put the shaders in when I import the model to Unity.
