ACES Maya ignores texture import settings

When I connect a texture map to aiStandard shader, no matter what I use as the input color space there is no effect in the render.


I have ACES 1.2 installed, OCIO config loaded etc. yet I still have a number of things that don't seem to work as expected.


Any help ?

For testing I don't use .tx files as takes ages to generate,I use the original .jpg with color profile assigned within aiImage and I have .tx generation turned off , although I did tests with .tx and didn't make any difference.

You need to remake the tx file everytime you change the input colorspace.

Hi Hyper, I presume you have the Color Space set to Utility - sRGB texture?

Once the .tx files are generated you should see speed improvements. Here are some of the benefits of using .tx files.

Are you deliberately trying to be unhelpful ? We do use .tx textures in production and I'm well aware of the benefits , speed improvements etc. but in this case it's irrelevant.


My issue has nothing to do with .tx textures, I have a problem with ACES not doing what it should do. Do you have any comments on that ?

If you use a tx file for your test, then we can check it with oiiotool -v --info, and see what color conversion was applied. So...change the color space on the image node, render and the tx is updated, check the tx and see what color-convert was used.

I'm using 'Utility - sRGB - Texture' for color inputs, 'Utility - Raw' for data.

My problem is that in my tests changing the texture's color space does not result a change in the render.

Render the shader ball scene here and if it doesn't match, upload the results.

First thing I got was a warning that your OCIO cinfig is missing , but I'm using ACES 1.2 anyways so I guess I just point the project to that file.
