The Render Appearance Library is a local, read-only library for render appearances. You assign render appearances to materials using the Materials dialog.
When you change the properties of a render appearance, the modified render appearance is stored as part of the project file. It is not stored in the read-only Render Appearance Library.

or image files used to define bump patterns or custom colors used
by the render appearance.
