Gamma and configurations

Compensating renders with gamma curve has always been a very hot topic. The reasons for this offsetting is required are already discussed in my book “Photography & Rendering with V-Ray“, so now I will focus on technical and practical details that will allow us to finally dominate all aspects related to the topic “Gamma”.

After it has started, click the “X” to view it in full screen:


  • Script: fileoutgamma = 1.0
  • Color mapping> Gamma: 2.2
  • Color Mapping> Mode: Color Range Mapping and Gamma
  • sRGB button to display preview / disabled


  • Script: fileoutgamma = 2.2
  • Color mapping> Gamma: 2.2
  • Color Mapping> Mode: Color Mapping only (no gamma)
  • sRGB button to display preview / enabled
  • This configuration is the default in V-Ray 2.4 and V-Ray 3

Both configurations produce the same result, with the difference that the configuration GAMMA2.2 facilitates saving images to 32bit and management of 3ds Max Frame Buffer and batch render.

Note: A “mismatch” window appears when we open a file with output gamma set differently from your system.
