Fake User is not preserved when appending into other blend file.

Hi, thanks for the report. I'm not sure about the Asset tag but fake user flag won't make any difference in 4.0, see: #113109
I don't think Asset flag is preserved with linked data in previous versions either. Does it work in 3.6?

Hi, thanks for the report. I'm not sure about the `Asset` tag but fake user flag won't make any difference in 4.0, see: #113109 I don't think Asset flag is preserved with linked data in previous versions either.

Hi,

You're right. Just checked and what 3.6 actually does is preserve Fake User (which is a by-product of Asset flag?). So that gets lost too in 4.0.

but fake user flag won't make any difference in 4.0, see: #113109

Unless I'm missing something, that could be quite problematic in some cases.

Scenario:

one or several characters + their armature scripts are linked into a few file
each script is Run (Alt P), one after another
after reopening the file, the scripts are gone

What's the solution?
To flag them again as Fake User, I need to make them local. So that's no solution. Just checked, I can at least set Fake User with Python while keeping it linked. But that means Python is required

Maybe I'm missing something?

When an unused (as in, having zero users) linked data-block needs to be kept in a blendfile, users are expected to reference them through a Custom Property (e.g. from a Scene, Collection or Object data-block)

Yes, I read this. Been using blender since 2004 but I had to ask ChatGPT for a script. Now figure out how to do this manually.
I hope other people can figure it out as well, as it doesn't seem very obvious.

Thanks, Pratik.

Oh, I need to set the custom property to Python and copy-paste the text datablock path into the custom property's Value.
