Using Maya's Render Command Line
3Delight renders can be launched using Maya’s Render command line with the '-r 3delight' option. If no additional parameters are provided on the command line, rendering will occur using the Render Settings that is active in the render settings window when the scene was saved.
The options contained in the Render Settings can be overridden using the command line interface. The following command is useful to list the parameters specific to the 3Delight for Maya plug-in:
Render -r 3delight -help
Here is a description of the available parameters (refer to Render Settings for more information about the effect of each options):

| Render Settings Selection |
|---|
-rendersettings <string>
-rs ?
| Specifies the name of the Render Settings to render with. Multiple Render Settings can be specified using a comma-separated list of names. Specifying all will sequentially render all Render Settings defined in the scene. Examples: ex 1:
Render -r 3delight -rendersettings settings1 ex 2:
Render -r 3delight -rendersettings settings1,settings2
ex 3:
Render -r 3delight -rendersettings all

-par <float>
not listed with -help | Specify the pixel aspect ratio of the rendered image. |
-crop <boolean> | Controls if the specified crop window is used for rendering. |
-cropmin <float> <float>
| Set the top right corner position of the crop window in X and Y, respectively. This implicitly sets -crop to true. |
-cropmax <float> <float> | Set the bottom left corner position of the crop window in X and Y, respectively. This implicitly sets -crop to true. |
| Quality (maybe remove all these options except pixel/shading samples?) |
|---|

|---|
-cpus <int> | Define the number of threads to use. The default is to use all available threads. | -texturememory <int> | Set the size of the texture memory cache, in megabytes. | -netcache <boolean>
maybe remove this and use netcache size instead (as in 3delight.config) | Toggle the use of network cache on or off. (Use to override the setting in the 3delight.config configuration file.) | -netcachedirectory <string> | Set the network cache directory. (Use to override the setting in the 3delight.config configuration file.) | -netcachesize <int> | Set the network cache size, in gigabytes. (Use to override the setting in the 3delight.config configuration file.) | | Progress |
|---|

Using 3Delight's renderdl Command Line
Offline rendering can also be launched using 3Delight’s standalone renderer renderdl — provided the scene have been exported to a NSI File. To render a file named file.nsi, just type:
To read more about about the renderdl command line, refer to Rendering NSI file.
