I wanted to have a try at hdri painting, so I opened an exr image and the LUT Management docker, enabled "Use OpenColorIO" and tweaked the exposure but nothing happened on the image.
I tried the Internal color engine, OCIO and OCIO (environment) and still the same.
Also all the options are empty when I select OCIO.
I have OpenColorIO installed from the Arch community repository.

What am I doing wrong ?

Have you also loaded an ocio config?

Hi,
Yes, this sounds like a known bug:
https://bugs.kde.org/show_bug.cgi?id=338357

Which is caused by this bug in OCIO:
https://github.com/imageworks/OpenColorIO/issues/379

So, you can try to use

Code: Select all

LANG=en krita

or

Code: Select all

LC_ALL=C krita

, that should workaround the issue.

Also, on current master I noticed I had to restart krita after enabling ocio and selecting profile, else the entries below in lut docker are empty.
