Bad network paths on symlink provided to OCIO.

Hi and thanks for Natron, we try to use it at work.

Problem

Natron seems to badly resolve network paths in Windows when providing it to OCIO.

We use natron over the network. Full path:

C:\app\inria\natron\2.3.4\bin\Natron.exe

This:

C:\app\inria\natron

...is a symlink to:

\\srvapp\app\inria\natron

When we put a reader we have:

Note the C:/app/inria/UNC/svrapp/natron/2.3.4... depict being correctly displayed into the project setting window.

We tried to override OCIO env var explicitly to an explicity path but no luck. The only "working" solution is to have a .ocio locally and point on it with the environment variable.

We use the portable version.

Steps to Reproduce

(Not tested but I guess, sorry for this)

Download the portable version. Put it into a folder accessible through the network. Let's say \\myserver\\natron.

Locally, create a symlink to this location:

mklink /d C:\mynatron \\myserver\\natron

Start Natron in C:\mynatron\bin\Natron.exe and read an .exr file.

When you set the OCIO env var to a custom OCIO, what happens? Does it work for a local OCIO config? does it work for a remote OCIO config?

Thanks,

When you set the OCIO env var to a custom OCIO, what happens?

If I set OCIO env var to an absolute path:

• If the path is "with symlink in it" (in our case: C:\app\inria\natron\2.3.4\Resources\OpenColorIO-Configs\blender\config.ocio): same problem (the message box).
• If the path is local (C:\Users\<user>\my_config\config.ocio): No problem.

Does it work for a local OCIO config?

Yes, setting the OCIO path to a fully local path works.

does it work for a remote OCIO config?

I just tested to put a fully network path (no symlink): \\server\natron\Resources\OpenColorIO-Configs\blender\config.ocio and it works, no message box and I can see my images.

So the problem is with symlinks using network: Local symlink pointing to network location. In our situation local symlink is C:\app\inria\natron pointing to network location \\srvapp\app\inria\natron.

@rodlie do you have a way to test this?

[rodlie]

Will test.

[devernay]

@rodlie is this fixed in the current version?
should this be considered a blocker for 2.4.3 (#752)

[rodlie]

I don't remember. Things might also have changed in OCIO v2. I will need to test this again.
