All about Gamma & V-Ray

Ciro Sannino

Lesson by Ciro Sannino | Official 5SRW study material.


  • VIDEO IN HD / Narrated / 24 ‘
  • MAX FILES to download with all V-Ray settings
  • Gamma output with 3ds Max 2014
  • Gamma uotput 1.0 and 2.2
  • Migrating from one configuration to another
  • Advantages and disadvantages
  • Successfully save images to 32bit
  • Duplicate the frame buffer with success
  • Batch render and render elements

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”.


  • 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.
