How to avoid material reimport via auto refresh when SketchUp file is saved?

I imported SketchUp file (.skp) to Unity. Then changed my material names and parameters that suits my scene. After a while i added more geometry (or changed) in SketchUp and saved but Unity’s auto-refresh feature ‘reimported’ all materials again (completely) and reapplied to my geometry.

I also tried disabling ‘import materials’ via import settings under Inspector but then Unity assigns default material to my geometry.

So, is there a way to keep my edited material applied on unchanged geometry when auto-refreshed?

Allright, apparently changing names ‘breaks’ the link and causes it to reimport materials. I was overthinking for some reason and didn’t even notice the hint given inside Unity. :eyes:

So, i’m giving proper names inside SketchUp and not touching it in Unity.
