Hi,
I have a problem: When I create Physical material and put it to my personal library, I cannot reach it from Physical Material dialog. See these pics:
And there is the view:
The same result is and with appearance dialog. Only way to use materials which I created is - Duplicate material/appearance to Favorites folder and access asset from there.
Would be good, that custom libraries come out in drop downs, because these workarounds with Favorites is a little bit annoying.
