Shader Graph project settings reference
Use the Shader Graph project settings to define shader graph settings for your entire project. To access the Shader Graph project settings, do the following:
- From the main menu select Edit > Project Settings. The Project Settings window is displayed.
- Select ShaderGraph.
| Property | Description |
|---|---|
| Shader Variant Limit | Set the maximum number of variants allowed in the project. If your graph exceeds this maximum value, Unity returns the following error: Validation: Graph is generating too many variants. Either delete Keywords, reduce Keyword variants or increase the Shader Variant Limit in Preferences > Shader Graph. For more information about shader variants, refer to Making multiple shader program variants. |
Custom Interpolator Channel Settings
It's impossible to limit the number of channels users can create in a Shader Graph. Use Custom Interpolator Channel Settings to create alerts that let users know when they're close to, or have exceeded, the channel limit for the target platform. Unity uses these settings to help Shader Graph users maintain compatibility with target platforms when using custom interpolators. For more information, refer to Custom interpolators.
| Property | Description |
|---|---|
| Error Threshold | Specify the number of channels at which users are notified that they're at, or have surpassed, the channel limit. This property has a minimum value of 8 channels and must be higher than Warning Threshold. |
| Warning Threshold | Specify the number of channels at which users are warned that they are close to the channel limit. This property must be lower than Error Threshold and between 8 and 32 channels. |
Heatmap Color Mode Settings
You can create multiple customized heatmap values assets and swap them in and out based on the current needs of your project. Use Heatmap Color Mode Settings to specify which custom heatmap values asset to use for your project.
| Property | Description |
|---|---|
| Custom Values | Specify which set of customized heatmap values to use for your project. |
