I'm searching a way to append a group in Python.

It should behave exactly like the Append function (ShiftF1) works, all objects should be local and editable. The idea is to append a character (with rig etc.) via Python and not Link it (to be able to modify it without making everything local one by one).

Thanks

  • $\begingroup$ Would you know ahead of time the blend file and path, as well as the exact group name that you want to append? Or do you need some type of browsing interface? $\endgroup$ Commented Jul 25, 2015 at 22:42
  • $\begingroup$ I already know blend, path and group name $\endgroup$ Commented Jul 25, 2015 at 23:01

Here's a solution. It appends an instance of the group (Blender 2.7x only):

import bpy filepath = "/path/to/file.blend" group_name = "CubeGroup" # append, set to true to keep the link to the original file link = False # append all groups from the .blend file with bpy.data.libraries.load(filepath, link=link) as (data_src, data_dst): ## all groups # data_to.groups = data_from.groups # only append a single group we already know the name of data_dst.groups = [group_name] # add the group instance to the scene for group in data_dst.groups: ob = bpy.data.objects.new(group.name, None) ob.dupli_group = group ob.dupli_type = 'GROUP' bpy.context.scene.objects.link(ob) # Blender 2.7x

Credit: solution is based on this answer: Import object without bpy.ops.wm.link_append

It's basically the same for objects:

import bpy # path to the blend filepath = "/path/to/file.blend" # name of object(s) to append or link obj_name = "Cube" # append, set to true to keep the link to the original file link = False # link all objects starting with 'Cube' with bpy.data.libraries.load(filepath, link=link) as (data_from, data_to): data_to.objects = [name for name in data_from.objects if name.startswith(obj_name)] #link object to current scene for obj in data_to.objects: if obj is not None: #bpy.context.scene.objects.link(obj) # Blender 2.7x bpy.context.collection.objects.link(obj) # Blender 2.8x

As of Blender 2.8 groups have been replaced by the new collection system:

import bpy # path to the blend filepath = "/path/to/file.blend" # name of collection(s) to append or link coll_name = "MyCollection" # append, set to true to keep the link to the original file link = False # link all collections starting with 'MyCollection' with bpy.data.libraries.load(filepath, link=link) as (data_from, data_to): data_to.collections = [c for c in data_from.collections if c.startswith(coll_name)] # link collection to scene collection for coll in data_to.collections: if coll is not None: bpy.context.scene.collection.children.link(coll)

    $\begingroup$ Sorry but this don't make it. This is the solution i have already, that's why i specified "behave like the append operator(shift F1) with everything local/editable". Here it behave like a link (ctrl alt o). i ll edit my first post to be more clear $\endgroup$ Commented Jul 26, 2015 at 9:55

    $\begingroup$ @Boris, There is a link argument, Set it to False to behave like Append $\endgroup$ Commented Sep 5, 2015 at 12:52
  • $\begingroup$ In Blender 2.8 replace bpy.context.scene.objects.link(obj) with bpy.context.collection.objects.link(obj) $\endgroup$ Commented Jan 9, 2020 at 18:10
  • $\begingroup$ @brockmann Re edit, TM chose tthe one? datablock type that has changed... groups become collections to make it 2.8+ compatico. $\endgroup$ Commented Jun 3, 2020 at 18:57
  • $\begingroup$ Ooops, thanks @batFINGER Added a collection example $\endgroup$ Commented Jun 4, 2020 at 12:16
