There are few steps you need to follow to set this up:
Download the Open Color IO configuration package from GitHub: https://github.com/colour-science/OpenColorIO-Configs
Set the OCIO environment variable and point it to the config.ocio file.For example, to set up the OCIO configuration with aces_1.2:
Windows: set OCIO=C:\OpenColorIO-Configs\aces_1.2\config.ocio Linux: export OCIO=/home/user/OpenColorIO-Configs/aces_1.2/config.ocio macOS: export OCIO=/home/user/OpenColorIO-Configs/aces_1.2/config.ocio
The existence of this environment variable controls whether Houdini automatically uses OCIO in various places.
For more information, see the Getting Started with Environment Variables page.
When rendering with V-Ray Standalone, an OCIO configuration can be set with the following OCIO environment variables:
VRAY_VFB_OCIO_INPUT_COLORSPACE – Specifies default OCIO input color space.
VRAY_VFB_OCIO_DISPLAY_DEVICE – Specifies default OCIO display device.
VRAY_VFB_OCIO_VIEW_TRANSFORM – Specifies default OCIO view transform.
For example, set a default OCIO input color space, display device, and view transform:
Windows: set VRAY_VFB_OCIO_INPUT_COLORSPACE = ACES - ACEScg Windows: set VRAY_VFB_OCIO_DISPLAY_DEVICE = ACES Windows: set VRAY_VFB_OCIO_VIEW_TRANSFORM = sRGB Linux: export VRAY_VFB_OCIO_INPUT_COLORSPACE = ACES - ACEScg Linux: export VRAY_VFB_OCIO_DISPLAY_DEVICE = ACES Linux: export VRAY_VFB_OCIO_VIEW_TRANSFORM = sRGB macOS: export VRAY_VFB_OCIO_INPUT_COLORSPACE = ACES - ACEScg macOS: export VRAY_VFB_OCIO_DISPLAY_DEVICE = ACES macOS: export VRAY_VFB_OCIO_VIEW_TRANSFORM = sRGB
Note that without setting these variables, it is not possible to render in ACES color space with V-Ray Standalone.
