Delete Branch "%!s(<nil>)"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?

b804f925c70c.Short description of error
Joining objects should initialize face sets per their source objects. Deleting the default cube breaks this feature for the file.
Exact steps for others to reproduce the error
TheCurseoftheDefaultCube.mp4
(No, this is not a joke about the default cube!)

This happens because the default cube in the factory startup file has a face sets layer. The "Initialize by Loose Parts" behavior when joining only happens when one of the meshes has face sets.
Joining mesh objects shouldn't create face sets from scratch when there are no face sets in the first place.
It is a bit confusing though, since there's no way to tell if a mesh has face sets if they all have the default value. To make it more predictable, I'd propose removing the face sets layer from the default startup file.
Ah, that makes sense.
Yeah this will also help the cases where beginning users who don't have the concept of face sets confuse the colors as a bug.

It looks more like a design issue that needs feedback from the #sculpt_paint_texture team.

This also applies to newly created geometry in edit mode, which used to be automatically marked as a new face set.
I'll look into the design of this. Personally I like that newly added geometry is always marked as a new face set,
but this behavior often lead to confusion and invalid bug reports for those that don't use or want face sets.
The new behavior has the upside that face sets are an opt-in feature.
@HooglyBoogly We discussed this in the recent module meeting. We all agreed that the new behavior after the recent changes is more desirable.
This way the user needs to intentionally create or initialize a face set first, so that face sets are automatically created on join or edit operations.
If they want to create face sets per joined object in hindsight, the Initialize operators can still be used.
Next we should adjust existing code that tries to create face sets when joining objects, to work with this new behavior.
Also, if an object that has face sets is joined into an object that has none, it will result in all face sets being lost. This needs to be fixed.
Any existing face sets must be joined into another object as well.
And yes, the startup files need to be updated.

Could you be more specific about what the join operator should do?
I wasn't able to reproduce this. Could you give steps to reproduce the issue? Thanks.

@JosephEagar Can you talk with Hans about this since you brought this up at the meeting? You are more familiar with the code.
You are right, I cannot reproduce this anymore either in the latest master.
Changed status from 'Confirmed' to: 'Resolved'
I'm going to close this since we can't reproduce it and the main issues have been resolved. If it comes up again, we can reopen this report or open a new one.
