I updated everything to the latest Unity Editor. Also realized I had the wrong shaders on my hairs, those are fixed and the hairs look MUCH better!

# Blackboard
|
|
|
|
## Description
|
|
You can use the Blackboard to define, order, and categorize the [Properties](Property-Types.md) and [Keywords](Keywords.md) in a graph. From the Blackboard, you can also edit the path for the selected Shader Graph Asset or Sub Graph.
|
|
|
|
|
|
|
|
## Accessing the Blackboard
|
|
The Blackboard is visible by default, and you cannot drag it off the graph and lose it. However, you are able to position it anywhere in the [Shader Graph Window](Shader-Graph-Window.md). It always maintains the same distance from the nearest corner, even if you resize the window.
|
|
|
|
## Adding properties and keywords to the Blackboard
|
|
To create a new property or keyword, click the **Add (+)** button on the Blackboard's title bar and select a type. For a full list of property types, see [Property Types](Property-Types.md).
|
|
|
|
## Editing properties and keywords
|
|
Select a property or keyword in the Blackboard or graph to modify its settings in the Node Settings Menu.
|
|
|
|
|
|
| Setting | Description |
|
|
|-----------|-------------|
|
|
| Name | The property's display name. The Editor strips quotation marks from display names and replaces them with underscores. Rename an item via the Blackboard by double-clicking on its name. |
|
|
| Reference | The name that Shader Graph uses internally for this property. Although the Editor populates this value by default, you can modify it. To revert to the original reference name, right-click on the word **Reference** (not the entry field) and select **Reset Reference** in the context menu. If the Reference Name contains any characters that HLSL does not support, the Editor replaces those characters with underscores. |
|
|
| Default | The default value of this property in any Material based on this Shader Graph. For example, if you have a Shader Graph for grass and expose the grass color as a property, you might set the default to Green.|
|
|
| Precision | Set the precision mode for the property. See [Precision Modes](Precision-Modes.md). |
|
|
| Exposed | Enable this setting to make the property available for you to edit via the C# API. Enabled by default. |
|
|
|
|
## Modifying and selecting keywords and properties
|
|
|
|
* To reorder items listed on the Blackboard, drag and drop them.
|
|
* To delete items, use the Delete key on Windows or Command + Backspace keys on macOS.
|
|
* To select multiple items, hold down the Ctrl key while making your selections.
|
|
* To cancel the selection of one or multiple items, hold down the Ctrl key while clicking on the items you want to remove from the selection.
|
|
|
|
## Using Blackboard categories
|
|
To make the properties in your shader more discoverable, organize them into categories. Expand and collapse categories to make the Blackboard easier to navigate.
|
|
|
|
### Creating, renaming, moving, and deleting categories
|
|
* To add a category, use **+** on the Blackboard.
|
|
* To rename a category, double-click on the category name, or right-click and select **Rename**.
|
|
* To move a category within the Blackboard, select and drag it.
|
|
* To remove a category, select it and press **Delete**, or right-click and select **Delete**. Deleting a category also deletes the properties within it, so move those you wish to keep.
|
|
|
|
### Adding, removing, and reordering properties and keywords
|
|
* To add a property or keyword to a category, expand the category with the foldout (⌄) symbol, then drag and drop the property or keyword onto the expanded category.
|
|
|
|
|
|
|
|
* To remove a property or keyword, select it and press **Delete**, or right-click and select **Delete**.
|
|
* To re-order properties or keywords, drag and drop them within a category or move them into other categories.
|
|
|
|
### Creating a category for specific properties and keywords
|
|
Select multiple properties or keywords and use **+** on the Blackboard to create a category that contains all of the items you have selected.
|
|
|
|
### Copying and pasting categories, with or without properties
|
|
You can paste empty categories, categories with all of their properties, and categories with some of their properties into one or more graphs. To copy a category with all of its properties:
|
|
1. Select the property.
|
|
2. Copy it with **Ctrl+C**.
|
|
3. Paste it into your target graph with **Ctrl+V**.
|
|
|
|
To copy a specific set of properties:
|
|
1. Select the category.
|
|
2. Hold down the Ctrl key.
|
|
3. Click the properties you do not want to include to remove them from the selection.
|
|
4. Copy the property with **Ctrl+C**.
|
|
5. Paste it into your target graph with **Ctrl+V**.
|
|
|
|
### Using categories in the Material Inspector
|
|
To modify a material you have created with a Shader Graph, you can adjust specific property or keyword values in the Material Inspector, or edit the graph itself.
|
|
|
|
|
|
|
|
|
|
#### Working with Streaming Virtual Textures
|
|
[Streaming Virtual Texture Properties](https://docs.unity3d.com/Documentation/Manual/svt-use-in-shader-graph.html) sample texture layers. To access these layers in the Material Inspector, expand the relevant **Virtual Texture** section with the ⌄ symbol next to its name. You can add and remove layers via the Inspector.
|
|
|
|
## Exposing properties and keywords
|
|
Unity exposes properties and keywords by default. This enables write access from scripts, so that you can edit them via the C# API, in addition to the graph. Exposed items have a green dot in their label. Enable or disable this feature in the **Node Settings** menu.
|
|
|
|
## Creating nodes
|
|
|
|
Drag a property or keyword from the Blackboard into the graph to create a node of that kind. Settings for a node in the graph are identical to those for the related property or keyword in the Blackboard. Expand these nodes to use a sub-member of the property value.
|
|
Property node names include a green dot if the property is exposed.
