Save your render settings as presets to avoid having to adjust them each time you render.
To save a preset, select Presets > Save Settings as Preset in the Render Settings window. You can save your preset as a .json file.
By default, your preset .json files are saved to <Documents>\maya\Presets.
You can also click the icon on the master layer Render Settings tab and select Export Current to save your preset.
To load a preset, select Presets > Load Preset in the Render Settings window. You can also easily switch presets in the Render Setup editor by clicking the icon on the Render Settings tab. Both global and user presets are available through these menus.
Select Presets > Set Preferred Preset to select a preset to be automatically loaded next time you create a new scene.
Presets are specific to a renderer, and only presets set to your current renderer appear in the Load Preset menu. Likewise, only the preferred preset that is set to your current renderer is loaded when you create a new scene.
You can delete user presets by selecting Presets > Delete User Preset. Global presets cannot be deleted from this editor.
You can save presets to a globally accessible network location so that they can be shared among users, or to a local folder that only you will access.
When you select Presets > Load Preset from the Render Settings window, global presets and user presets are listed via separate right-click menus.
You can set the location for your global presets by setting the environment variable MAYA_RENDER_SETUP_GLOBAL_PRESETS_PATH. Upon startup, Maya automatically searches for global presets in this folder. You can modify this path via the Preferences window. This way, you do not need to restart Maya to modify this path.
Set the location for global and user presets in the Preferences window (Windows > Settings/Preferences > Preferences), Rendering section, Render Setup Preferences sub-section.
You can also set your preset location using the following option variables:
Global presets: renderSetup_userPresetsDirectory
User presets: renderSetup_globalPresetsDirectory
By default, this is set to <Documents>\maya\Presets.
To query either of these directories, do as follows:
optionVar -q "renderSetup_userPresetsDirectory";
To change the directory, replace the value of the option variable as follows:
optionVar -sv "renderSetup_userPresetsDirectory" "C:\myUserPresets";
Maya automatically searches for available presets in these directories.
