Overriding Global Renderer Options for a Pass

If your global renderer options are set exactly as you like them, but you need to make a few minor parameter tweaks for a specific pass: create an override containing only those renderer options and then modify them just for that pass.

You can create a pass override by marking the parameters in the global renderer options property editor. The parameter marking method for overriding renderer options is only available from the render manager.

You can also create property overrides by using the Get > Property > Override command on the Render toolbar: the result is the same, so it is just a matter of how you like to work. For more details about working with overrides in general, see Overriding Properties [Scene Elements].

To add parameters to the override by marking

1. Open The Render Manager.

2. In the explorer view, expand the pass node that uses global renderer options for which you want to create an override.

When you expand the Pass node, its renderer is displayed in italized letters indicating that it is a global property.

3. Select either mental ray or Hardware Renderer.

4. In the right panel, the Global Renderer options are displayed. Mark (by selecting) the parameter names of each parameter you want to override. Marked parameters are highlighted in yellow.

When selecting you can do any of the following:

- Click to select a single parameter and deselect any others.

- Shift+click to add a parameter to your selection.

- Ctrl+click to toggle a parameter.

- Ctrl+Shift+click to deselect a parameter.

5. When you have finished your selection, choose Edit > Override Marked Pass Parameters from the render manager’s menu buttons. The selected parameters are added to the PassOverride property editor and a PassOverride node is displayed under the pass node.

6. You can use the controls in the override property editor to change the values of the overridden parameters.
