Besides the materials/appearances available from the application...
....is there some other kind of library / repository / available collection one can access ?
I'm less interested in the physical material properties here than in some bigger choice of visual materials.
I'm aware that I can customize materials myself and upload my own bitmaps etc., but I was really hoping to find something to "browse" rather than to "create". And the other way around: Maybe a place to "upload" some materials for the general good of the community and people to come...
