Properties panel
The Properties panel shows parameters and properties of layers that you select in the Layers panel. The best way to find out what parameters do is to play with them and see what impact they have on your asset.
The parameters that appear in the Properties panel depend on what you’ve selected in the Layers panel. Sometimes one layer can have more than one set of customizable properties, for example a material layer that isn’t at the bottom of the stack will have blend properties. Each icon in the layer stack is a different set of properties and parameters. For a material layer with both material properties and blend properties, there will be two icons on that layer.
In the above image of the Layers panel, each icon in the layer stack has a different set of parameters to control the appearance of your material. For example, the Clay layer has both the Clay icon, and the blend icon, each of which has a separate set of parameters.
