Short description of error
Duplicating objects using the copy-paste buffer, the Copy on Duplicate Material preference is ignored, and a duplicate is always created.
Note: Paste-buffer does not update the UI, so some deselection/selection is required for the UI to show the actual material.
Exact steps for others to reproduce the error
(4) (Make sure the UI is updated, deselect, select object)
Video included
Thanks for report, but this is misunderstanding. This settings mean that material will be duplicated and assigned to copy, or original material will be there. This is not about
create copy without materials. And as i can see of your video, everything is works correct.OK, but:
"or original material will be there"
does not apply. Regardless of ON or OFF, a duplicate material will be created (.001, .002 etc) . The Paste Buffer ignores ANY setting on Copy on Duplicate Material preference?
( I would love if the original material was there if OFF)
Em, the material is duplicated despite the Preference, it is not the original material on the duplicate.
Think this is a legit report, not sure what you were seeing in the video @mod_moder ?
Ah, sorry, misunderstand mean of report. Well, now i can not confirm your issue. Can you check latest 4.0 blender from https://builder.blender.org/download/daily/?
This might not be how the Copy/Paste functionality was designed, but I think it should actually respect those settings (even if they are meant for the
Duplicateoperator)Latest 4.0 and factory settings:
I can confirm, issue in
Copy Objectsoperator in menu.yup! (same issue)
(note the UI update thing)
ed: oops, did I post while tags were being changed/accidentally close the issue? sorry for the reopen if not wanted!
Well, since copy/paste is more like save (at a tmp place), then append back, these preferences dont actually act on this.
Conceptually they probably should, but atm. they are not meant to be used here.
My second thought vote would be to close this as an accidental feature request, but will leave up to @mont29 to decide.
Paste Buffer does not respect Copy on Duplicate Material preferenceto Copy/Paste objects Buffer does not respect "Duplicate Data" (Material, Mesh, ...) preferenceThe TL;DR: Would be that current copy-paste is very old code, and could be improved in many, many ways. Part of it may be addressed by the improved 'append & reuse' at some point this year, but the whole feature would need a complete check-up.
So for the time being, would indeed consider that current behavior is as expected from a code side. Will open a generic 'Update Copy/Paste' design task though, to keep track of the topic: #116890
