Aces workflow katana

[jimmy.longhurst]

Hi,

I am trying to get parity between arnold renders from maya and katana. I am only testing the albedo diffuse colour map at this stage.

In maya, on the file node, I can set the colour space to be Utility - sRGB - Texture (diffuse colour is a jpeg file). In Katana with an arnold image node, the colour_space is set to auto. There is no drop down so I am unsure of all the types of colour spaces available.

When set to the default auto there is a slight colour difference between my katana render and the maya one (katana on bottom, has a slightly greener tint to it)

Looking through the katana docs, I went through the following page

https://docs.arnoldrenderer.com/display/A5KTN/ACES+Workflow

Are there additional steps required here? My understanding is as long as you declare an OCIO env variable (set to the ocio config path), katana should read that in correctly.
