# How can I independently pose Group Instances?

I would like to add two instances of a model created by makehuman to a scene.

After linking one model (File/Link) and adding a proxy Ctrl-Alt-P. I used Add / Group Instance to add another instance but after that both models change pose when I make changes in pose mode.

How can both models be animated independent from each other?

This a follow-up of an earlier question how-can-a-rigged-model-be-used-multiple-times-in-a-scene

On Linux (have not tested on Mac) I recently used the following method to create layout for a shot that required 3 instances of a procedural rock creation rig. Then i created a proxy of the armature from each of the group instances and posed them accordingly.

Starting with two folders: one containing an asset file and the other where my shot file exists. In the asset file the Rig/Geometry is grouped.

blend:~/demoProceduralRocks>> ls
asset/ shot1/


Since I want to create create a scene that should have 3 identical instances of the asset, I create hard links to the file in the shot's import folder

blend:~/demoProceduralRocks>> cd shot1/import/

blend:~/demoProceduralRocks/shot1/import>> ln -v ../../asset/Rock.blend Rock.instance.1.blend

blend:~/demoProceduralRocks/shot1/import>> ln -v ../../asset/Rock.blend Rock.instance.2.blend

blend:~/demoProceduralRocks/shot1/import>> ln -v ../../asset/Rock.blend Rock.instance.3.blend


This is how it looks after creating hard links

blend:~/demoProceduralRocks> ls -lirt asset/ shot1/import/
asset/:
total 172
22217836 -rw-rw-r-- 4 blend home 169297 2013-05-27 15:22 Rock.blend

shot1/import/:
total 516
22217836 -rw-rw-r-- 4 blend home 169297 2013-05-27 15:22 Rock.instance.3.blend
22217836 -rw-rw-r-- 4 blend home 169297 2013-05-27 15:22 Rock.instance.2.blend
22217836 -rw-rw-r-- 4 blend home 169297 2013-05-27 15:22 Rock.instance.1.blend


Then I layout the shot file by linking the groups from the hard linked files created above. Then I make a proxy of the Armature and Pose each proxy separately. (A demo of this in action)

blend:~/demoProceduralRocks> tree ./
./
|-- asset
|   -- Rock.blend
-- shot1
|-- Layout.shot1.blend
-- import
|-- Rock.instance.1.blend
|-- Rock.instance.2.blend
-- Rock.instance.3.blend

• thanks, this works also on windows mklink /H link.blend original.blend (+1) – stacker Jun 18 '13 at 8:40
• Thank you for confirming about the fact that it works on Windows also. :) – satishgoda Jun 18 '13 at 8:43

Separate the same model into different blend files. Also give different group names.

For example, you have one character, let's say the name was char.blend. Then save as the char.blend into files with different names such as char_a.blend, char_b.blend. Make sure the group also has a different name. So now, you can link both files, and both will be independent.

• Thanks, that is the workaround I currently use, I looking for a method to use one single model multiple times in a scene since I edit it and add more poses. – stacker Jun 17 '13 at 11:27
