When you create a layer, a material is associated with it automatically. By default, the material displays the source image on the layer surface using the Standard shader, which gives you immediate access to the full range of parameters in the Materials tab.

To access the Materials UI:

1. Do one of the following:
   • In the Layer Editor, select a layer and then select the Materials tab.
   • In the Schematic view, right-click the Reaction node and select Edit Group to display the Group Schematic, and then click a material node to select it.

     The Materials UI displays the properties for the selected material node.
