V-Ray 5 acescg workflow settings

First step ：

Method 1 ： Manual settings
open VFB panel “Display Correction”— choice “OCIO”— Load the file （ Find... According to the path OCIO The configuration file config.ocio）

Check the following settings ：

Enter the color space ：ACES—ACEScg

The third step

Change all material maps to V-ray Bitmap , And modify the color space transfer function and RGB Color space

The first way ：

Maps are converted in four categories ：

‍‍‍‍‍‍‍‍HDRI Mapping ： Color space transfer function — nothing RGB Color space —SRGB

Grayscale and other data type maps ： Color space transfer function — nothing RGB Color space —RAW

VR Color mapping ： choice ACEScg（ modify RGB Primary color is enough ）

Other Map ： Color space transfer function —SRGB RGB Color space —SRGB‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

summary ：
The second way ：

According to different mapping types , Add the corresponding suffix , such V-ray Can automatically identify ;
