Overview

Redshift can render scenes outside of a host application using the Redshift CmdLine tool. Exporting a scene for rendering with the Redshift CmdLine tool is as easy as exporting a Redshift proxy. Each frame of an animation is exported as a standalone Proxy file, which is then loaded into Redshift CmdLine and rendered.


Exporting a scene

In order to render a scene with the CmdLine tool the proxy must contain all of the necessary elements for your project including the render camera, lights, materials, geometry, animation, global render options, and AOV setup. Set these things up before exporting your proxy.

The output name for the render files can't be changed after a proxy is created, this protects the AOVs there were set up in the host application. However, the output folder can be changed using the -oip argument.

 

 

Launching the Command Line tool and rendering a scene

To render a scene with the command line renderer first we need to understand the syntax expected by the redshiftCmdLine. The syntax describes the formatting and order necessary to render a scene.

The most important part of the syntax is to first designate the redshiftCmdLine path and then designate the path of the Redshift Proxy file. The order and the formatting of this is very important, there must be a space between both paths and they must come in this order:

(redshiftCmdLine path) (proxy file path)

 

On Windows

Using the Windows Command Prompt we can start rendering our scene. In the command prompt window first we need to designate the path to the redshiftCmdLine tool, by default this is found at: C:\ProgramData\redshift\bin\redshiftCmdLine.exe. The proxy file path should point to the proxy file on your PC. A real world example looks like this:

C:\ProgramData\redshift\bin\redshiftCmdLine.exe C:\demo\proxy\RS_Proxy_Demo.rs

 

Typing the above into a Command Prompt and hitting enter will start rendering the scene but there are many ways to use the Command Prompt, like dragging and dropping first the redshiftCmdLine and then the Redshift Proxy file directly into an open command prompt with a space in between. Each time a file is dragged into the window, the path is automatically copied into the command prompt as demonstrated in the video below.

Using the redshiftCmdLine in Windows

 

On Mac

Using the Mac Terminal we can start rendering our scene. In the terminal window first we need to designate the path to the redshiftUsdCmdLine tool, by default this is found at: /Applications/redshift/bin/redshiftCmdLine. The USD file path should point to the USD file on your Mac. A real world example looks like this:

/Applications/redshift/bin/redshiftCmdLine /Users/username/Documents/RS_proxy.rs

 

Typing the above into a Terminal window and hitting enter will start rendering the scene but there are many ways to use the terminal, like dragging and dropping first the redshiftCmdLine and then the Redshift Proxy file directly into an open terminal with a space in between. Each time a file is dragged into the window, the path is automatically copied into the terminal.

 

Command Line Arguments

Command line arguments are options that can be used to modify the behavior of the tool and the rendered output. These are added after the proxy file path, this describes the order:

(redshiftCmdLine path) (proxy file path) (command line arguments)

 

Here is a real world example, note the space between each section:

C:\ProgramData\redshift\bin\redshiftCmdLine.exe C:\demo\proxy\RS_Proxy_Demo.rs -oip C:\demo\proxy\images

 

To see a list of available arguments, run the redshiftCmdLine without any arguments.

Not enough parameters

Usage:
  redshiftCmdLine scenefile [-oip PATH] [-opbp PATH] [-oro FILENAME]
                  [-gpu N] [-cachepath PATH] [-texturecachebudget N]
 or
  redshiftCmdLine -listdevices
 or
  redshiftCmdLine -listrenderoptions
 or
  redshiftCmdLine -fileinfo proxyFilename
 or
  redshiftCmdLine -printdependencies proxyFilename

Parameters:
   scenefile is the .rs proxy file containing the scene to be rendered

   -oip followed by a path, overrides the image file paths
    This includes the paths of all the AOVs
    For example, if a scene normally renders images:
      z:\myprojectpath\images\myscene.exr
      z:\myprojectpath\images\myscene.diffuseLighting.exr
    You can redirect them to c:\myfolder by doing:
      redshiftCmdLine test.rs -oip c:\myfolder
    This will produce images:
      c:\myfolder\myscene.exr
      c:\myfolder\myscene.diffuseLighting.exr

   -oif followed by an extension, overrides the image file format
    This includes the file extensions of all the AOVs
    For example, if a scene normally renders EXR images:
      z:\myprojectpath\images\myscene.exr
      z:\myprojectpath\images\myscene.diffuseLighting.exr
    You can turn them into PNGs by doing:
      redshiftCmdLine test.rs -oif png
    This will produce images:
      c:\myfolder\myscene.png
      c:\myfolder\myscene.diffuseLighting.png

   -opbp followed by a path, overrides the point-based technique file paths
    This includes the photon mapping, irradiance point cloud, irradiance cache
    and subsurface scattering generated or loaded files
    For example, say a scene produces an irradiance point cloud file at:
      z:\myprojectpath\pointcloudfiles\irradiance_pointcloud_auto.234.rsmap
    You can redirect the point cloud files go to c:\myfolder by doing:
      redshiftCmdLine test.rs -opbp c:\myfolder
    This will produce the file:
      c:\myfolder\irradiance_pointcloud_auto.234.rsmap

   -ores followed by a resolution of the form <w>x<h>, overrides the output resolution
    For example, to render the images in 1920x1080 resolution do:
      redshiftCmdLine test.rs -ores 1920x1080

   -oro followed by a filename, overrides render options using a text file
    The text file should contain option name-value pairs on each line, for example:
      UnifiedMaxSamples 1500
      UnifiedFilterSize 3.4
      ProgressiveRenderingEnabled false
      MotionBlurEnabled true
      UnifiedFilterType RS_AAFILTER_MITCHELL
    To list the render options, use -listrenderoptions

   -device followed by the device ordinal N enables that device for rendering
    For example, to render scene 'test.rs' with the first two devices, do:
      redshiftCmdLine test.rs -device 0 -device 1
    Use -device all to enable all devices
    If -device is not specified, the devices specified in the preferences.xml are used

   -gpu is an alias of -device used for backward compatibility

   -hybrid followed by 0 or 1 overrides the HybridRendering preference

   -cachepath followed by a PATH, sets the cache path folder
    The default Windows cache folder is '%LOCALAPPDATA%\Redshift\Cache'
    The default Linux cache folder is '$REDSHIFT_LOCALDATAPATH/cache'

   -texturecachebudget sets the texture cache size (in megabytes)
    For example, to render scene 'test.rs' and set the tex cache to 20GB, do:
      redshiftCmdLine test.rs -texturecachebudget 20000

   -listdevices lists all the available devices and exits

   -listgpus is an alias of -listdevices used for backward compatibility

   -listrenderoptions lists the available render options and exits

   -crop followed by cropOffsetX cropOffsetY cropWidth and cropHeight in pixels sets
    a custom cropped region to be rendered
    For example, to set the crop region to (10,10) - (30, 30), do:
      redshiftCmdLine test.rs -crop 10 10 20 20

   -fileinfo followed by the proxy path, prints out various bits of
    information about the proxy file

   -printdependencies followed by the proxy path, prints out a list of
    the files referenced by this proxy

   -skippostfx skips the postfx processing, so no postfx or color correction
    will be happening on the final rendered image

   -ocioenv followed by 0 or 1 overrides the OCIO environment variable behavior
    If 0 is specified, the OCIO environment variable is always ignored
    If 1 is specified, the OCIO environment variable is used if available
    If this option is not provided, the scene preference is used

   -ocioconfig followed by a path, overrides the OCIO config file used
    This option will implicitly cause the OCIO environment variable to be ignored

   -ociorenderspace followed by a string overrides the OCIO rendering color space

   -ociodisplay followed by a string overrides the OCIO display name

   -ocioview followed by a string overrides the OCIO view name


Example: Overriding the folder path of the rendered images

When rendering with redshiftCmdLine, by default the images are saved in the path chosen in the 3d app. This can be undesirable because that path might be pointing to a folder that doesn't exist in the computer running redshiftCmdLine!

For this example let's assume our proxy file "myscene.rs" normally renders the following two images in a network folder (drive "z").

z:\myprojectpath\images\myscene.exr

z:\myprojectpath\images\myscene.diffuseLighting.exr

 

If drive "z" is not accessible from the computer we're currently rendering from, we can redirect the images to c:\myfolder via the -oip argument as shown below:

redshiftCmdLine myscene.rs -oip c:\myfolder

 

Doing so will render the images to the following path instead:

c:\myfolder\myscene.exr
c:\myfolder\myscene.diffuseLighting.exr

 

Example: Overriding render options

Render options can be overridden using the -oro argument. In this example let's assume we want to force the unified min/max settings to min:16 and max:64.

First we need to create a text file (in this case: myrenderoptionsoverrides.txt) containing the following two lines:

UnifiedMinSamples 16
UnifiedMaxSamples 64

 

Then, we pass this text file to redshiftCmdLine as follows:

redshiftCmdLine myscene.rs -oro myrenderoptionoverrides.txt

 

This renders myscene.rs with the two unified sampling overrides.

 

Example: Listing all render options

Running redshiftCmdLine with the -listrenderoptions argument lists the available render options, as shown in the dropdown below.
