Create Render Settings overrides for your render layer

Click the Scene icon at the top of the Render Setup editor to switch to the scene (master) layer, then double-click the Render Settings tab to open the Render Settings window. This opens the Render Settings for your scene.

The range of frames being rendered is also displayed. It may indicate Current Frame, or Frame 1-10, for example, if you have set a Start frame and an End frame.

Create Render Settings overrides for a render layer

1. Middle-mouse drag and drop the Render Settings tab from the top of the Render Setup editor to your render layer.
2. Click on the layer.

3. Double-click the Render Settings tab in that layer to open its Render Settings window.

4. Right-click the attribute that you want to override in the Render Settings window and select Create Absolute Override for Visible Layer or Create Relative Override for Visible Layer.

   An override automatically appears beneath the Render Settings tab in the Render Setup editor.

5. Select the override and adjust its value in the Property Editor.
Note: After you create the override, a red border may appear around the layer visibility icon ; click this to refresh your layer before you render in order for the overrides to be reflected in your render.

Select any Render Settings override, and the Property Editor indicates the node to which it is applied; for example: Applied to defaultResolution node. This indicator appears on all Render Settings overrides created in Maya 2017 Update 3.

This indicator may be helpful in cases when you create overrides on two or more attributes with the same name on different nodes.

For example, in this case, there are two overrides named width. The Property Editor indicates Applied to defaultResolution node for the former:

and Applied to defaultArnoldFilter node for the latter for easy identification.

Note: You cannot drag and drop the Render Settings collection in a render layer into another collection within the same layer.

Display the Render Settings for each render layer

To open the Render Settings for any layer, including the scene layer, click on the layer, then double-click its Render Settings tab.

When viewing the Render Settings for a specific layer (including the scene layer), the Render Settings tab for the corresponding layer appears with a grey border.

You can only display the Render Settings window for a layer that is visible. If you switch to another layer (by clicking on the layer) while the Render Settings window is open, the Render Settings window automatically updates to reflect the settings for the visible layer.

The converse is also true. If you use the Render Layer drop-down list in the Render Settings window to display the Render Settings for a different layer, that layer is automatically set as visible.
