Color Management and Environment Variables

[Rendering0101]

Hi guys,

For context: I am working in ACEScg color space in SP and want to export ACEScg color maps, but I have to make sure the input maps have the correct color space (sRGB for color data).

OCIO is set up in the Windows Environment Variables, and this is how the Color Management configuration looks like when I open a new SP project.

All good so far.

The problem is that the drop-down menus below are now greyed out, so can't choose Utility-sRGB-Texture for Bitmap input color space.

Any idea why this is?
If I disable the OCIO from Environment Variables and choose OCIO manually, these menus are available. However I prefer to keep using Environ. Variables.

I remember this used to work before.

Thank you.

See the documentation linked below which states, 'If the OCIO environment variable is present, and specifies a valid configuration file, it will override and disable the settings in UI.'  So those greyed out and incorrect settings should not be having any impact, which in turn is why it makes sense to grey them.

The change was made in version 8.1.2. See release notes below:

Understood, thank you so much Dave. I somehow missed this detail in the documentation.

No problem - I had to look it up myself 🙂
