Short description of error
In attached file Vertex group are not displayed on instances.

Exact steps for others to reproduce the error

  1. Create object A and instance it to object B.
  2. Now add some vertex groups to instance B
  3. instance A doesn't have those groups displayed. But if you add any vertex group to instance A then vertex group from obj B, will be now displayed on obj. A.

Expected behavior:

  • obj. A and B should display Same vertex Groups, because they are instances.

Sample file with two instances, with vertex groups assigned to second instance:

Thanks for the report, but no bug here. Unfortunately, vgroups are (partly) defined in objects, which means instancing a same mesh from different objects is not enough to share its groups, this is a known limitation of current code and not considered a bug.

I had this same question and made a post about it as well. Than why is it show under data panel? Is it so that its close to the data properties, that does make it easier. But its very confusing of why these are not transferred.

What i found weird about it, is that the groups do show as bpy.data.object[MESHNAME]??
