This page presents the Preferences window and all its settings.
You can find the Preferences window through the Edit menu in the main top bar the application. This dialog lets you adjust a number of settings. It is organized in tabs covering different areas of behavior and functionality.
We recommend reviewing all of these settings to get a better insight on how the application operates and how it can be tailored to your workflow.
Recent documents list contains
This allows you to select the number of documents to list in the Recent Packages entry of the File item in the Main Menu.
History stack size
This indicates the number of available undo operations at any given time in the Edit > Undo item of the Main Menu.
The more undo operations you need, the more memory the application will require.
Choose the language of the application
This setting defines the language used in the application interface.
Changing this setting will only take effect after restarting the application.
Invert zoom in views
Determines whether the suggested save/export path is your last selected path, or the SBS package's path. The last selected path is saved across sessions.
When the image data of a graph exceeds the allocated memory pool (see below Memory > Image Cache), the overflowing data is written on disk. This setting lets you define the location the overflowing image cache data is written to.
This location is also used to store a copy of the currently open SBS package with the latest modifications since the last manual save.
The application keeps in cache a full-resolution, uncompressed image for each rendered node in the current graph.
Instance nodes will generate these images for all nodes of the graph they reference, and delete them once their outputs have been computed. Only the outputs are kept in memory at that point.
You can set the maximum cache size allocated to thumbnails and images in system memory, and see the current usage. If the cache data overflows its allocated pool, the excess data is written to the Temporary Folder (see above Paths > Temporary Folder).
This allocation is calculated automatically to approximately 75% of the total system memory pool. To set this value manually, select the Custom option and set a value in the adjacent input field.
Please note writing to disk is orders of magnitude slower than writing to system memory. Therefore, graph rendering time will increase exponentially as overflowing data needs to be written to the Temporary Folder.
To prevent this from happening, we recommend taking a look at the suggestions for decreasing a graph's memory footprint in the Performance Optimization Guidelines section of the documentation.
During specific tasks, such as image conversions for thumbnails or the 2D View, separate jobs will be created and distributed across the system processing cores for efficiency. Each job will write data to system memory to perform its operations.
This setting lets you define the allocated memory pool for all concurrent jobs. When this pool is entirely used, new jobs will be queued until the current ones have completed.
This allocation is calculated automatically to approximately 10% of the total system memory pool. To set this value manually, select the Custom option and set a value in the adjacent input field.
Disable High DPI
High DPI mode will maintain consistent scaling of text and user interface elements independently of the system's display and scaling settings.
Changing this setting will only take effect after restarting the application.
An auto-save feature is included by default, which creates copies of the current state of open SBS packages at set periods of time. Auto-saves are placed in an .autosave folder at the SBS package location.
Auto backup every # minutes
The time period between each auto-save.
| Keep up to # versions|
The maximum number of auto-saves to keep at any given time.
When the maximum amount of versions is reached, newer backups will delete the oldest backups.
Please also note auto-saves should be opened after moving them to the original SBS package location. They should not be opened at their current location.
Publishing and sending SBSAR files
Alawys save .sbs file when publishing to .sbsar or sending to another application
Cooking Size Limit
GPU Cache Limit
This setting lets you define how much memory should be reserved for caching render stages. Usually, the engine will cache the output of each node in a Substance 3D graph.
Please refer to the Projects settings page.
Tab key shows node menu
If checked, the Tab key will open the Node Menu, replicating the functionality of the 'Space' key.
Enable creation of nodes by click-dragging connectors
If checked, when you click on any connector, drag the cursor and release the created link in graph empty space, the Node Menu will be displayed.
The menu will also be filtered according to the type of the connector which was clicked on. This means only nodes which are compatible with the clicked connector will be displayed.
View outputs in 3D view when opening a graph
If checked, all graph outputs are automatically applied in the 3D View when that graph is opened.
This also has the effect of rendering all nodes which are part of a stream leading to an Output node.
Substance compositing graph
Automatically compute all nodes thumbnails when opening a graph
If checked, automatically render all node thumbnails when loading the graph.
View output in 2D view when opening a graph
If checked, the first graph output is automatically displayed in the 2D View when that graph is opened.
This also has the effect of rendering all nodes which are part of a stream leading to that Output node.
Automatically display newly created compositing node
If checked, the 2D View will automatically update to display the output of a newly created node.
Automatically insert color/greyscale conversion node
If checked, automatically resolve Color/Grayscale connection types mismatches, by placing specific nodes to perform the appropriate conversion.
When a Grayscale output (gray connector) is connected to a Color input (yellow connector), a Gradient Map node is automatically placed between the two connectors.
Enable graph editing in context
By default, when opening a graph referenced by an instance node with a right-click on the node and selecting Open Reference, that graph is loaded and edited in isolation.
If checked, you can edit graphs referenced by instances using the information passed in the instance by the current graph. To do this, right-click on an instance node and select Open Reference In Context, or use the Ctrl+E keystroke.
This means an instanced graph can be edited in the context of the graph it is instanced into. This is very useful for seeing the effects of the edits on the graph you were working in. See example below.
Open Reference In Context
| Environment hidden by default|
Determines the Environment default visibility setting. When hidden, the backdrop of the 3D View is replaced with a solid color.
Lets you can also define the factor by which the texture applied to the environment is scaled down.
Controls the scaling of the 3D View's rendering resolution when the system uses display scaling.
| Sample Count|
Impacts the size of the 3D View shaders' sample table . A higher value will result in higher image quality at the cost of performance.
The shaders' sample table is also impacted by the system's GPU and OS.
Defines which hardware resources are allocated to Iray
computation. The list should include the CPU and all compatible NVIDIA GPU(s) detected.
If a compatible NVIDIA GPU is detected, the GPU is checked and the CPU is unchecked by default.
Learn more in the Hardware acceleration section of the Iray page.
If checked, raytracing will be performed on the GPU for compatible bakers.
The following GPU raytracing backends will be the default depending on the GPU architecture:
Optix: Nvidia Pascal/Maxwell
You can use the following command line arguments when starting the application to force the use of a different GPU raytracing backend:
--force-optix: force the use of Optix on Nvidia Turing or newer GPUs
--force-dxr: force the use of DXR on Nvidia Pascal GPUs
|The option will trigger a recalculation of all Library thumbnails, which will automatically replace the previous ones.|
You can assign custom keyboard shortcuts for creating nodes in graphs.
Any node can be assigned a shortcut, even custom library nodes. A same shortcut can be assigned in different graph types. No shortcuts are assigned by default, you are free to customize this to your liking.
In case of a conflict with another node shortcut, or a built-in program shortcut, the entry will be highlighted a warning will be displayed. The shortcut will have no effect until the conflict is resolved.
