This property editor contains parameters that control a texture layer's effect on one of a material/shader's ports.
To display, do any one of the following:
Open a material/shader's property editor. If the material/shader has texture layers, a layer property editor is appended to the main property editor for each layer. A layer/port property editor is appended to the main layer property editor for each port to which each layer is applied.
From the texture layer editor, select a layer and press Enter to open its property editor. A layer/port property editor is appended to the main layer property editor for each port to which the layer is applied.
Locate the material/shader in the explorer. Expand its Texture Layers Layername Ports node and choose the port to open its layer/port property editor.
Select a layer in the material panel. The property editors of its ports are displayed in the lower portion of the material panel.
