So I have a model of a chair with several LODs. The problem is that a material element in one of the LODs seems to be permanently linked to an element in one of the other LODs- but they shouldn’t be. One of the elements is supposed to be a metal arm rest (LOD2, element 5), the other element a plastic seat back (LOD3, element 0).
When ever I assign a material to one of those elements, the other one adopts the same material and I can not find a way to unlink this relationship.
