%%%A small patch to allow environment variables in paths for linked libraries.

For example with MY_PROJECT=dummy and MODEL_RESOLUTION=lowres the path:
/projects/$MY_PROJECT/character_${MODEL_RESOLUTION}_v001.blend
will be translated to:
/projects/dummy/character_lowres_v001.blend

note:
I've left in a printf to show translated paths in the console, I think it could be useful to see the real destination when loading a library at startup or when changing a path in the outliner...%%%

%%%Assigning to ton.

At a glance, this seems ok, but I'd suggest making a set of .blends that fully test this, in as many different path situations as possible.%%%

Hi!
There is a lot of value to be able to use env vars in paths, most particularly for the scene's output file (because sometimes you don't control how blender is launched and cannot add a "--render-output" parameter, for example) . AFAIK some studios are using this (old but working) patch in production without problem.
How can we help to reevaluate the inclusion of this patch?

Hi !
I can confirm what @maximd said.
We use this old patch for years without any problem.
Maybe, it's a good thing to have this feature in official blender versions.

I have been contacted by @kyraneth about this patch being a topic that came up several times at the Blender conference and a wanted feature by some studios. @mont29 Do you think this would be something worth adding?

I updated it for current master (though not 100% sure the change in readfile.cc is correct).

For thoses who need env var to be kept in 3.3(.2) LTS, here is another patch based on this one -> https://developer.blender.org/D16760 .
It support browsing in blender UI with env var in path.
