ACES is the Academy Color Encoding System and developed by the Academy of Motion Picture Arts and Sciences. ACEScg is the version of the ACES encoding system for computer graphics, widely adopted in the industry. It has become the industry standard, because compared to sRGB, ACEScg works with a lot more color information, illustrated in this gamut graph.
V-Ray 5 and V-Ray 6 come with an implementation of the ACEScg out of the box and in this tutorial we explain the render setup in V-Ray for 3ds Max in this color space. V-Ray supports only ACEScg as the primary color space of choice in CGI.

The VThe V-Ray ACEScg workflow does not require an active OCIO configuration. In V-Ray 5 and later, the relevant ACEScg transformations are part of the V-Ray core. However, if you do decide to use an OCIO configuration, the OCIO environment variable needs to be set and pointing to a suitable OCIO configuration. See theUsing OCIO configuration section below for more information.
