The overall goal is to allow someone posting a version to easily include others in the ‘conversation’ so to speak, but in a more impromptu way, without having to previously set up anything.
Not everyone wants to be set as a reviewer or follow a shot or task. This is more of a ‘hey, can you take a look at this?’ thing that would be more spontaneous.
For example, you are submitting a comped version of the shot, but you want the FX/Sim artist to take a look at how their particles came out in the render. Not for every single comp version, though.
As you have helped clarify, there’s no way to add a reviewer or cc field at the same time a version is being created, which would have been the easiest ways to do this as far as I can tell.
The only way I see how to do that sort of ‘one off’ cc: is to create the version, and then have to add a note afterwards with the cc: added.
I wouldn’t have thought this to be an odd sort of capability to ask for. But I know that most projects are likely way more organized and administered than our student projects, which probably makes this type of feature less needed.
