V-Ray for Maya and Gamma Settings

Hello!

My name is Alex Tacu and I want to explain what are the correct gamma setting that you need to use when you render with V-Ray for Maya.

Firs of all let’s have a look what result you get when you don’t set anything.
For this I made a simple scene with 3 cubes.
The left one has a simple VRay Material whit the difuse color set to pure white (255, 255, 255)
The middle cube hase allso a VRay Material but this time in the difuse channel I pluged in a texture.
The right cube has a simple VRay Material whit the difuse color set to pure red(255, 0, 0)
Render setting are like this:



The result is like this:



this is too dark
iso on the physical camera was 100, i’ll set it to 400:




As you can see, colors look much better but the texture that i used for cube doesn’t have the same color as the original.

So to fix that we need to change a few render settings:



Set gamma in color mapping to 2.2
Check “Linear workflow”
And the result looks like this.



So these are the few steps that i personaly use in my workflow to get the best result with VRay for Maya
To recap:
Color mapping:
Type: ExponentialGamma: 2.2Check “Linear workflow”VRay Physical Cameara enabled (iso 350-400, depending on the scene)Sun and Sky created
