As you work in a render layer and create Render Settings and AOV overrides, you may want to export a .json of the Render Settings with their override values applied, then import this preset into a new scene. Likewise, you may want to export and import the AOVs with their override values applied.
To export the Render Settings with their override values in the current layer
You can also select Presets > Export Render Settings in the Render Settings window, or click in the Scene > Render Settings section of the Render Setup editor. A dialog appears, informing you that the overrides in the visible render layer will be included with the exported .json.
Exported files are saved to your user presets location, which is, by default, <Documents>\maya\Presets. See Global presets and user presets for more information.
The .json is applied as a preset in the new scene.
In this example, selecting File > Export Visible Layer Render Settings creates a .json that includes these values: AASamples Max value is set to 5, motion blur is disabled, and the width and height values are set to 1280x720. In other words, the override values are applied to the exported preset.
To export AOVs with their override values in the current layer
You can also select Presets > Export AOVs in the Render Settings window, or click in the Scene > AOVs section of the Render Setup editor. A dialog appears, informing you that the overrides in the visible render layer will be included with the exported .json.
Exported files are saved to your user presets location, which is, by default, <Documents>\maya\Presets. See Global presets and user presets for more information.
The AOVs, with their overridden values, are added to the new scene.
In this example, selecting File > Export Visible Layer AOVs creates a .json where the direct AOV is disabled, and where the Png Format is set to int16 for the diffuse AOV. In other words, the override values are applied to the exported preset.
Only enabled overrides are considered when exporting.
In this example, the Image Size > Width attribute is set to 960 in the scene layer. There are three overrides on the attribute. Each override multiples the value by 0.5.
Only two of the overrides are enabled; therefore, the value that is exported is 960 x 0.5 x 0.5 = 240. The disabled override is not considered when exporting.
