Quick Instance

by multlabs in Scripts and Addons

I copy group in other file, then I try to edit it by pressing tab, Blender gives me an error: Instance of Collection "Group.name" doesn't located in scene "library"

This is one of the limitation of the script. In order to make the group editing workflow it is necessary to collection of this group to be in the scene "Library". In your case I recommend to do following:

1. Open Outliner in "Blender file" mode

2. Then find your group in Collections and scene "Library" in Scenes.

3. Then simply drag and drop your group from Collections to the Scene Collection Inside "Library"
