Hi There,

Arnold is here. It’s super easy to use with Maya’s Color Management System.
Just use the default settings (forget the gamma nodes).

A Simple guide to Color Space settings in file nodes:

  • Set Color Space to sRGB for textures which are directly responsible for colors.
    (For example: Diffuse Color, Specular Color, Reflection Color, Refraction Color, Transmittance.)
  • Set Color Space to RAW for textures which contain non surface color information.
    (For example: Roughness, Opacity, Bump Map, Normal Map, Displacement Map, IOR.)

As simple as that.

Automatic .tx conversion is also great (“on” by default).

Cheers, D
