Just a quick question, is this corelating to our present way of doing CMS accross the all host?

I mean CMS should be set withing global OP Settings so is this still the case or?

Global CMS and OCIO config defined in OP Settings

and for Max host specifically:

and for Max host specifically:

The color configuration should be taking the last OCIO config file(aces 1.2) from the global CMS after set colorspace in OP menu or start a new scene.
The configuration is the same with the one in Houdini.

So if the user wants to customize for hosts, they can add their own configuration files in config path and enable override global ocio config, their setting will override the global configuration file within Max.

Ok cool then...I was more worried it doesnt work like that :) ...so all good

Will test asap. thx!

Haven't tested it, but code looks good.

Meanwhile when testing (will post comments on that soon) ...we should also treat case of older workfiles in max set to Gamma Workflow which being 3dsmax default one (at least in max 2024 )

We should somehow force our OCIO config based CMS...
or at least user should get sort of Warning that OCIO color management not set and need to be switched to our custom OCIO config.

This mainly happening when re opening older max workfiles before this PR.

Maybe we can do an action similar to the one in maya which fix fps when the old 3dsmax workfile scene is being opened....
A very small menu pops up and ask the user to click to set the OCIO config

[LiborBatek]

@moonyuet yeah, is as simple as going into Max Preferences and choose custom OCIO config based CMS (our config already being in the list present just not set as working color management setting)

...basically just not being switched on

[LiborBatek]

Now OCIO correctly been visible when creating Render instance

I propose to keep it exposed on Render instance when re opening Publish now its not being visible after going into it again...so user is not aware/able to change color profiles anymore easily

I am also not sure whats intended function for that Set Color Space OP menu entry too?

Right now nothing happen/ is shown to the user when triggered. Also checked if by any chance switching the max CMS Preferences but not. Even its name implying something different.

[moonyuet]

I have updated the scripts with collect review can set colorspace and the colorspace options move to the publish tab.
Also for the old workfile it would have the popup menu but for some reason the color of the push button is not applicable for the main_window set for max.

[LiborBatek]

All seems working fine. Max being correctly set to OP OCIO config file and if not,
then the pop up menu shows with option to fix that. Also works fine.

There is now visible the option box on render instance for color profiles too, so user has opportunity to tweak the color profiles later on if needed.
