Graph parameters
This page describes the standard parameters for the Substance Compositing Graph.
A graph has several parameters that you can modify. You can find them by either clicking on empty space in the graph, or selecting the graph item in the Explorer panel. Parameters will be then displayed in the Parameters view.
Base parameters
The Base Parameters section includes parameters which have an impact on all the nodes it contains. Every node in this graph which have one or more Base Parameters set to Relative To Parent inheritance method will get their corresponding values from the graph's.
In most cases, inheritance plays a significant role in defining these values, and how these values changes throughout the graph. It is strongly recommended to acquire a good understanding of inheritance in Substance compositing graphs before using these values.
Output Size | This parameter allows you to chose the base resolution of images in the graph. Read more about the Output Size. Default: (0,0) - Relative To Parent |
Output Format | Allows to choose base bit depth in the graph, from these options:
Default: 8 Bits per Channel - Relative To Parent |
Pixel Size | Defines the pixel size. We recommend leaving both Width and Height values set to 1. Default: (1,1) - Relative To Parent |
Tiling Mode | Defines the base tiling mode in the graph from these options:
Default: H and V Tiling - Relative To Parent |
Random Seed | Defines the base random seed for the graph. Default: 0 - Relative To Parent |
Attributes
The Attributes section contains metadata for the graph, which provides information for identifying, categorising and applying the graph as designed by its author.
Identifier | This is the name of the graph, and must be unique – you cannot have two or more graphs with the same Identifier in the same package. It is used as the graph's name in the Explorer panel. You can use only the following characters for this value: A-Z, 1-9, @$%[{]}_- Default: New_Graph, or set by user at graph creation |
| Label | The Label is used instead of the Identifier to display the name of the graph for better readability in user facing scenarios – e.g. Library entry or Instance node label. Reminder If you rename a graph – e.g. in the Explorer, you may also want to change the label! Default: Empty |
| Type | the Type is used to define the intended purpose of a Substance Graph. It is mainly used together with Send To functionality. |
| Physical Size | This indicated the span the texture would have in the physical world, in X (length), Y (width) and Z (height). It is therefore inherently related to the material which is produced in the graph. The Physical Size can be used, for instance, to display the texture at its correct ratio in the 2D View and 3D View. The Z value is currently not taken into account in the 3D View. The Height Scale value for the material should therefore be set using an Output node set to the heightscale usage, or directly in the Material Properties. Default: (0,0,0) |
| Icon | This area lets you define an icon which will be used by the Library to display this graph's entry, both as an SBS and an SBSAR. The icon is also used in other situations, such as Substance Painter's Shelf. The area offers the following options:
The Generate option uses the Physical Size to determine the PBR Render's Height Scale for its displacement effect. When no icon is defined, the first image output for the graph is used instead. Default: Empty |
Package | The absolute filename for the Package this graph belongs to. The Folder button can let you open a new system file browser window at this location. Default: Package filename / Empty if package was never saved |
Exposed in SBSAR | This controls whether the graph and its outputs can be viewed in the SBSAR file published from the graph's Package. This is useful if some graphs in the package are only used as subgraphs for the main graph of the package, and should not appear in the SBSAR. Default: Yes |
| Show in Library | Controls whether the graph should be visible in the Library, if the package is stored in a location which is watched by the Library. Default: Set in the Library tab of the Project Settings |
Description | This is the description text of the graph. It is visible in the tooltip for the graph entry in the Library, any Instance node for this graph, and software with an existing Substance Integration. Default: Empty |
Category | You can this field to set a category for this graph item in the Library. Default: Empty |
Author | You can use this field to put the name of the author. Default: Empty |
Author URL | This field lets you input an URL – e.g. the author's website. Default: Empty |
Tags | You can use this field to add your own tags, for improving the searchability and discoverability of the graph. Default: Empty |
User Data | You can use this field to add your own additional data. This is useful for custom integrations in third-party software. Substance 3D Painter and Sampler make use of this userdata to set certain specific behaviours. Default: Empty |
