After dabbling with the decals I ended up with a message when opening the Rhino file saying “missing image file”. Not a showstopper, In this file I have already replaced it with numerous dupes… but how can I find a way to delete references to missing pictures?
After digging a bit I found out a list in the Decal’s property panel, but in the droplist there’s no option to delete entries in the list (it’s full of dupes after several attempts to apply decals).
It looks like the problem in the file opening message i caused by the all-blackish texture (looks like an empty texture with missing picture?).
And yes, how to get rid of all the dupes? There should be a menu option to delete. Anyway, I tried Purge but it doesn’t care about these dupes.
