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:

rend_set1


The result is like this:
rend1
this is too dark

iso on the physical camera was 100, i’ll set it to 400:
rend2

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:
rend_set2 
Set gamma in color mapping to 2.2
Check “Linear workflow”

And the result looks like this.

rend3 

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: Exponential
Gamma: 2.2
Check “Linear workflow”
VRay Physical Cameara enabled (iso 350-400, depending on the scene)
Sun and Sky created

Thanks for reading.

    The reason why your image looks too dark is because you're seeing a linear image on a SRGB monitor. Since you're using Vray, make sure you turn on the SRGB button in the VFB before messing with the camera ISO.

    Ah, so that's why my AO was grey, thanks man. To answer the above comment the Vray Physical Camera can be found by selecting the camera, then in the attribute editor, click attributes/vray then tick physical camera, you can adjust the settings for it by selecting the camera then attribute editor then it's at the bottom under extra attributes.
