This page provides information on the Color management rollout.


Overview

The Color Management rollout allows you to switch between sRGB and ACEScg workflow. The ACEScg is a linear color working space that specifies a wider gamut of colors than the sRGB linear gamut. It allows for a greater range of colors transformations in post as its gamut envelopes not only sRGB, but also P3, Rec709, and Rec2020. Archived assets in ACEScg do not need to be remastered in case the displays standards are improved in future.

For more information on the ACEScg workflow, see ACEScg Workflow Setup.

Parameters

Rendering RGB primaries – Selects a display color space for the rendered image. The selected mode is saved as metadata to vrimg. The color space used in the render also affects how the rendered image is displayed in VFB when the default Display correction sRGB is set in VFB.

sRGB – Image is rendered in sRGB color space. This is the color space for most monitors and computer displays.
ACEScg – Image is rendered in ACEScg color space. This color space allows for greater range of color transformations in post. It has a wider gamut of colors than the sRGB linear gamut and should be encoded into a 16 bit floating exr.

Auto RGB primaries for VRayBitmap textures – When enabled, automatically sets RGB primaries for the VRayBitmap texture.


When using the ACEScg color space, any 8-bit texture map should be renamed according to the color space that they are in, using “_lin_srgb”, “_srgb” or “_acescg” suffix.

If neither is present, the map is assumed to be in the renderer color space as specified in the Color management rollout (in this setup, ACEScg). If the texture maps are properly named, auto recognition can be used by enabling the Auto RGB primaries for VRayBitmap option.
