I have used BlenRig and MakeHuman. They have two different methods for
applying a rig. I'm not sure of the specific method used in MH but they
have figured out how to apply various rigs to meshes more accurately than
my results with BlenRig.
You might also want to look there for some ideas.
What is currently missing is a way to transfer anims from one model with a
different scale to another model. I have made various tests with the
xonotic rig from MH and found that the official xonotic rigs are approx
2.5 times larger than the MH version and that causes stretching along the
A simple method for merging the anims from different models with the same
rig without stretching the mesh would be very useful. Then we could rig
the model with an arbitrary rig using the MH method and apply the anims
from other existing models with the same rig easily and quickly. My tests
so far have required me to export the rigs and anims from Blender in iqe
format and merge them manually to get the anims from one model to another
but that results in stretching.
MH already have a MakeRig plugin for blender that allows exporting a rig
bvh for use with their internal format and my plan is to ad an iqe/iqm
exporter to MH too which is one way to avoid stretching/scaling issues.
