Work with layer overrides

To override materials and shaders on a per layer basis: method 1

1. In the Render Layer editor, select a layer.
2. Select Window > Rendering Editors > Hypershade.
3. Select a material from Hypershade, or create a new material, and assign by -clicking and choosing Assign Material Override from the marking menu.
   

   This creates a material and assignment that will override all shader assignments to objects on the current layer.

To override materials and shaders on a per layer basis: method 2

1. You can also override materials and shaders on a per layer basis by -clicking on a layer in the Render Layer editor and selecting Overrides > Create New Material Override or Assign Existing Material Override from the menu that appears.

   You do not need to have a layer selected to use the context-sensitive menu; -clicking an unselected layer still allows you to override its materials.

To override materials and shaders on a per layer basis: method 3

1. Select a material from Hypershade, or create a new material. To assign this material to the layer, select the layer and middle-drag the material swatch over the object.
   
   

To remove a material override

1. -click on the layer, and select Overrides >Remove Material Override from the menu that appears.

To override layer attributes (render flags) on a per layer basis

1. In the Render Layer editor, select a layer.
2. Open the Attribute editor by -clicking on a layer and choosing Attributes from the menu that appears.

   The Member Overrides section of the layer attributes appears.

3. Click a render check box (for example, turn off Motion Blur, turn off Cast Shadows, or assign a shading group to all objects in that layer).

To override render settings, including the renderer, on a per layer basis

1. In the Render Layer editor, select a layer.
2. Open the Render Settings; for example, by clicking the controls (render settings) icon on a layer, or select Window > Rendering Editors > Render Settings.
3. -click on a setting name and choose Create Layer Override from the menu that appears.

   The settings you can override on a per-layer basis include: Render Using, Edge Anti-Aliasing, Size Units, and Resolution Units.

   When a render setting override is applied, the clapboard icon on the layer appears in color (red) .

To remove a render flag override

1. -click on the layer, and select Overrides >Remove Render Flag Overrides from the menu that appears.

To remove a render setting override

1. -click on the layer, and select Overrides > Remove Render Setting Overrides from the menu that appears.
   Note

   You cannot create overrides on the Master layer: any change you make to render settings on the Master layer propagates to all layers that derive from it.
