Re: New to OCIO, and viewer processes in Nuke

Jeremy Selan <jeremy...@...>

The other issue is that the nuke-default ocio config is intended to
work in other applications other than nuke. And many of these other
apps dont automatically include a 'none' option by default, the same
way Nuke does.

Do you have concerns about removing the default Nuke 'None' option?
As ben mentions, register_viewers() should be removing all of the
original options.

Alternatively, as a compromise we could place the None option at the
bottom of the list. Thus, while it would be duplicated in your case
at least the second copy wouldn't be getting in the way of the real

I should also note that at Imageworks, while we of course use
OCIODisplay for our viewer, we dont rely on the public
register_viewers() call to register the nodes. I forget the exact
reason but it relates to splitting up the registration into two parts
( vs. so knob defaults can be appropriate set on
startup. I'll ping our nuke guru to add further details.

Hi all,
New OCIO user here... Just playing around with it to see how it'll fit into
our colour pipeline. Primarily playing with the Nuke side of things so far.
One small thing that's cropped up is how, when using the nuke-default
config, there are two "None" items in the viewer process drop-down.
I'm thinking that None probably should still be left in the menu in
ocionuke.viewer.register_viewers(), and the config files should just not
re-define a None. I'm thinking that the nuke-default config file should
maybe reflect this

As I'm quite new to OCIO, I didn't want to start forking and making a pull
request for this kind of change, so I thought I'd bring it up on here first.
