Layers/BSDFs/Coatings/ Emitters/Displacements/Textures
These pages all work similarly. At the top of the hierarchy in each page is a ‘Catalog’ node; as such, each page represents a catalog of
items. There are only two other types of nodes used in these trees:
Volumes: these contain either other volumes, or components
Components: an individual BSDF, Emitter, Coating, etc.
Components can be dragged back and forth between the Material Editor’s layers tree and their respective Database Manager page.
They can also be edited in-place while stored in the database by double clicking them in the Database Manager; the Material Editor will
be emptied, and the selected component will be loaded into the appropriate Material Editor page.
The components stored in the database are saved automatically whenever a document is saved, and there is no need to be concerned
with the files they are stored in; these files are plugin-specific and located somewhere in the app-data folder under your user profile.
This location is used to make sure the plugin has permission to write these files. In addition to being saved when the current document
is saved, there is also a ‘Save Changes’ button which will appear in the Database Manager’s top toolbar whenever changes have been
made which would be lost were the document to be closed without saving – clicking the button will commit the current state of all
database components to disk, so it is possible to save them without also saving the document.
