OpenColorIO with sbsrender

Substance Designer 2019.3 support OpenColorIO (https://opencolorio.org/).

The examples assumes that you are already familiar with OCIO and a color workflow like ACES. SAT and SD provide three different color workflows (luts and config files are present in $SAT_INSTALL_DIR/resources/ocio):

• Legacy, the color workflow used in previous versions. Legacy uses the old color engine.
• Aces, the Academy Color Encoding System (https://en.wikipedia.org/wiki/Academy_Color_Encoding_System) which provides a set of color transforms adapted to the tv and cinema industry. Aces uses the OCIO color engine.
• Substance, a simplified Aces workflow. A selection of the most used colorspaces in the VFX and animation industry. Substance also uses the OCIO color engine.

A new set of flags have been added to sbsrender to control OCIO:

--ocio Specify an OpenColorIO configuration to use (can be a config.ocio present in $SAT_INSTALL_DIR/resources/ocio). If you don't set this flag the legacy color engine will be used.

--output-colorspace Specify the colorspace name for outputs. --output-colorspace sRGB.

Input colorspace is controlled using:

--set-entry-colorspace Specify the colorspace to use for an input. --set-entry-colorspace input_id@sRGB..

Output colorspace is controlled using the following flags:

--set-output-bit-depth Specify the bit depth of an output node. --set-output-bit-depth output_id@16f

--set-output-colorspace Specify the colorspace name for an output. --set-output-colorspace output_id@sRGB

--set-output-format Specify the image format of an output node. --set-output-format output_id@exr

The new colorspace pattern {colorspace} will be converted to the used colorspace when generating filenames.

Example of using OCIO in sbsrender command line:

Note, The substance file must have been authored with an OCIO workflow in Designer work properly. If using bitmap resources the cooking must be done with OCIO option (sbscooker --ocio or publishing using Substance Designers publish feature)

The colorspace value must correspond to a colorspace present in the config.ocio file.

sbsrender render /path/to/ocio_graph.sbar --output-name "ocio_{outputNodeName}_{colorspace}" --output-colorspace Linear --set-output-colorspace basecolor_output@sRGB --set-entry bitmap_input@/path/to/bitmap.png --set-entry-colorspace Linear --ocio $SAT_INSTALL_DIR/resources/ocio/substance/config.ocio
