Linear workflow – This option is deprecated and will be removed in future versions of V-Ray. When enabled, V-Ray automatically applies the inverse of the Gamma correction that is set in the Gamma field to all V-Ray Material (VRayMtl) materials in your scene. Note: this option is intended to be used only for quickly converting old scenes which are not set up with proper linear workflow in mind. This option is not a replacement for a proper linear workflow. For more information, please see the Linear Workflow example below.
Example: Linear Workflow
This example shows the same image rendered with 3 different settings for Gamma and Linear Workflow.
Recommended Settings for Proper Linear Workflow
There are different ways to approach a proper linear workflow. The simplest and most effective approach is to leave all gamma-related settings in 3ds Max and V-Ray at their default values.
