RenderMan features robust support for the industry-standard ACES color management system, and other color spaces, such as the popular Filmic Blender, in all bridge products, including the interactive RenderMan Image Tool.
OCIO Configurations
RenderMan ships with a number of OCIO configurations :
LINEAR-sRGB
The original Sony Pictures Imageworks configuration has been used since the dawn of time.
ACES-1.2
The visual effects standard Academy Colour Encoding System for filmmaking and computer graphics.
FILMIC BLENDER
A popular BT.709-based configuration provides a high dynamic range and other effects typical in film stock. Developed by Troy Sobotka.
Configuration selection
- $OCIO: Use the color space defined by your systems environment variable. Typically sRGB.
- Off: Scene Linear is defined as the scene-wide color space.
- ACES1.2: Use the ACES 1.2 color encoding system that ships with RenderMan 24.
- Filmic Blender: Use the popular BT.709 color space.
- Custom: Allows for a custom color space file to be specified.
| Please note that you will need to close and re-open IT when switching between OCIO configurations for the new color space to be correctly displayed in IT |
Color managed items
- UI color values
- All DCC apps provide a color-managed color picker that will return a color in the rendering colorspace. RenderMan simply uses them as-is.
- Lights
- Color Temperature was computed in Rec.709 before 24.0 and is now color-managed.
- PxrEnvDayLight is also color-managed and relies on the srgb_linear role.
- Textures
- Textures MUST be converted to the rendering color space before usage. This task can be accomplished by the Texture Manager.
- It is also possible to use the PxrColorSpace pattern to convert a texture color, but at a performance cost.
- Patterns
- PxrBlackBody is color-managed.
- PxrHairColor is color-managed.
- PxrColorSpace allows artists to convert from one color space to the rendering space.
