To set an attribute for one node
You can select the node in the Hypershade, in the Node Editor, or in the Outliner.
If you are creating a shader graph, you can adjust your render node attributes in the Hypershade Property Editor. By default, the Property Editor displays render nodes in a template view that is optimized for shading workflows, and has a simpler layout that lists only the most commonly used attributes. You can switch to the Attribute Editor view by clicking in the Property Editor.
