 If a property is not exposed, you can still edit it. To edit the property for every Material instance that uses the selected Shader, open the Shader Graph Asset and edit the property directly in the Blackboard. To edit the property for a single Material instance that uses the Shader, use a script.

 ### Material properties in concrete nodes

 - When you modify the properties of the Master Mode in a Shader Graph, Unity does not synchronize them with Materials unless the Material is open in the Inspector. This means that, when you change certain properties in the Master Node settings, like **Material Type**, Materials that are not open in the Inspector fall out of sync, which breaks the rendering of these Materials. To fix the rendering and synchronize the properties of a Material with its Shader Graph, you can do the following:
 
 - - Open the Material in the Inspector, change the value of one of its properties, and then change it back. This triggers a sync between the master node and the Material, and fixes the Material.
-  - Call `HDEditorUtils.ResetMaterialKeywords(Material)` from a C# script in your Project. This synchronizes the properties of the Material you pass in with the Material's Shader Graph.
