The Library
This page presents the Library panel of Substance 3D Designer, its layout as well as the tools it offers for searching and filtering content.
Overview
The Library panel is a split-view resource manager, where you can find and gather all your assets you need to work with in your graph.
It monitors folders on your hard drive or over a network which are added to the list of Library watched paths in the Project Settings. Any changes happening in those folders – addition, removal and update of content – are carried over to the Library.
About custom content
See the Curating custom content and filters section of the documentation for more information.
The Library can monitor all assets which are supported Resources:
- Graphs from Substance Packages (SBS) and Substance Archives (SBSAR)
- Bitmap images
- Vector images
- Function graphs
- MDL graphs
- AxF files
- Fonts
- Meshes
The panel is split in 2 main parts :
- The Categories section on the left
- The Content section on the right
Categories
Located on the left of the Library panel, the Category section contains all the assets categories (i.e. folders) and filters, as a tree view.
You may click on any item in this tree view to display its content, along with the content of all its child items.
The categories
Default categories and filters contain all the assets shipped with Designer. They cannot be edited or removed.
The default categories include:
- Favorites : gathers all the assets you have flagged as 'Favorite'
- Generators : contains all the graphs that will directly compute/generate content without the need of a previous input (in most cases)
- Filters : contains all the substances that will modify their input
- Functions : the nodes that are used in Function Graphs
Content
The content of the Library is displayed as labelled thumbnails. These thumbnails will have a different aspect depending on the following factors:
- Substance graphs in SBS and SBSAR files are represented by their first output, or by their icon if one was set by the graph's author
- Bitmaps and vector graphics (SVG) are represented by a miniature render of the bitmap itself
- 3D meshes, Function graphs, MDL graphs, fonts and AxF files are represented by generic icons for each type
In case of thumbnails issues
Our recommended troubleshooting step for any issues related to Library thumbnails (incorrect image, rendering stuck on the refresh icon, etc.) is to manually trigger a thumbnails refresh.
To do this, use the Rebuild thumbnails button in the Library section of the Preferences Window.
Use an asset from the Library
To use an asset from the library, drag and drop it to the desired location.
You may select multiple items in the Content section by holding the Ctrl key while clicking on items. In this case, the drag and drop operation will place nodes in the graph for the entire selection.
Search an asset by name
The Search bar, located at the top left of the Content section, lets you search any asset by name. When searching for content in this manner, the current selection in the Categories section is ignored, and the entire content in the Library is searched.
You can filter the search results by graph type, using the 
Filter by... icon next to the Search bar.
The search bar will take into account the name of the asset you are looking for, but also tags that the asset can contain, or the category it belongs to.
For example, typing 'Normal' will list all the assets that can be used to generate or modify a normal map. This is a good way to discover new nodes, and thus new possibilities!
Vizualize your assets
Using the 
Display Mode drop-down button, you can select the display size for content items.
The 
Toggle Labels button lets you display or hide the labels of the nodes.
When placing the cursor on a content item, a tooltip will appear after a short time displaying a description of the item if its author has provided one.
Right click on the item to display additional information, including a hyperlink to display the file associated with the item in the system file browser.
Favorites
You can add any item in the Content section to your Favorites list, using the 
Add to Favorites button. The button also lets you remove content from this list if it is already added.
When content is added to this list, it is available in the Favorites category of the Library, and will be displayed at the top of the Node menu list when searching for a node in the graph, provided the search terms match it.
