File3dmMaterialTable Material Duplicates

Hi @moritzcramer @nathanletwory
This is a problem I also asked for help on and received none.

Custom Preview component stops displaying in many view modes

Since the fix is a long way off. How do you parse that list to sort out the dups or instances?
Like I said in my post you end up with thousands of materials and worse if you bake out and undo the list fills with nulls. Can’t we get a quick component that filters out the dups as a workaround for now must be doable in Gh python?
