Short description of error
New/copy button work different, accordingly materials or particle systems for example.
It do not create copy. Also there is no direct way to create copy (duplicate) of GN-tree (and indirect have a bug now T86207)

Event Timeline

It is inconsistent with the other mentioned, not sure it is a bug though.

Workaround for making real copies of the nodegroups:

  • Outliner > Blender File view > Node Groups > copy / paste

Scene and View Layers also use this icon, but use submenu: New, Copy Settings, etc.

Already tried.
Direct copy-paste have a bug.
Copying from Blender file structure creates grouped node instead tree. And ungrouping will ruin input and output

So, actually no workaround, that will give exact same result.

OK, will confirm for now and check soonish

Dalai Felinto (dfelinto) moved this task from Backlog to Community Tasks on the Geometry Nodes board.

OK, since this is marked as good first issue for community contributions, will step down.

Hi, I have a working fix for this, but I have a question about how it should be implemented. I was wondering if I should implement a new operator that copies the active tree in the geometry nodes modifier, and keep the old NewGeometryNodeTreeAssign. Then assign the new operator to the relevant button, or if I should just change the functionality of NewGeometryNodeTreeAssign to copy the active tree if it exists?
