The Layering Scheme area displays all layers of the material. In addition to obtaining basic information in this area, you can also perform several tasks.
When you select a layer, the icon to the left is highlighted in blue and the horizontal bar is displayed in dark gray. To move a layer up or down, click the layer, and then click an arrow.
The gray bar in each layer shows the assigned material (metal, basic, etc.) and the layer’s weight with respect to the other layers.
Tip: Drag the layer’s bar to increase or decrease the layer’s weight.
You can change the type of the layer at any time (without losing the assigned textures, colors, and values) by clicking the icon at the left and selecting a different layer type.
