I am getting these warnings in Houdini 20.0.537 - running Redshift 3.5.21, on Windows 10, using the native Houdini OCIO config.
I can see these entries listed in the config under 'inactive_colorspaces'. Am I the only one getting these warnings?

: Inactive 'Rec.1886 Rec.2020 - Display' is neither a color space nor a named transform.
: Inactive 'Rec.1886 Rec.2020 - Display' is neither a color space nor a named transform.
: Inactive 'Rec.1886 Rec.2020 - Display' is neither a color space nor a named transform.
: Inactive 'Rec.2100-HLG - Display' is neither a color space nor a named transform.
: Inactive 'P3-D60 - Display' is neither a color space nor a named transform.
: Inactive 'P3-DCI - Display' is neither a color space nor a named transform.
: Inactive 'P3-DCI - Display' is neither a color space nor a named transform.

Looks like the diplays were pruned from the config without updating the inactive displays list. The inactive displays flags what to exclude from the display ui. Listing displays that don't exist has no effect.

Thanks. Maybe I can just edit that inactive displays list without breaking anything?

EDIT: I've just removed those entries from the inactive displays list and all seems to be well - based on a quick test render.

yes, OCIO configs are meant to be user editable

Please can you tell me in which menu they can be deactivated?

the config is just a text file. you can open it in an editor and delete the invalid items from the list.

If you open the ocio config editor in Houdini and save the config, an editable copy will be saved in the user prefs folder by default, or can be saved manually anywhere of your choosing.

There answer is it doesn't exist. You have to edit it first.

For those struggling as I was, and needing more specific directions: The file is located in two places:

C:\Program Files\Side Effects Software\Houdini 20.0.547\packages\ocio\houdini-config-v1.0.0_aces-v1.3_ocio-v2.1.ocio
C:\Users\<user>\Documents\houdini20.0\ocio\houdini-config-v1.0.0_aces-v1.3_ocio-v2.1.ocio

Open it up, and look down to Line 42, which should start with "inactive_colorspaces"; remove all the entries inside the bracket so that it reads:

NOTE: You have to adjust this in both directories (it didn't work for me if I only replaced it in the Documents folder); if you don't have the file in your Documents\houdini20.0 folder, you can just copy it from the C:\Program Files location & paste it inside a manually-made OCIO folder inside documents.

I also made sure that my ocio.json file in my Documents\houdini20.0\packages folder was set to the following (one of our team didn't have an OCIO package file, so made it manually:

Thank you LukeLetellier! that has been bugging me for weeks
