Retargeting to humanoid characters with different shapes! #134

Hi, Thanks for the great work and for sharing the code. I was wondering how to retarget the model (without re-training) for humanoids with different body types (i.e. different arm lengths, mass, size, ...). Are you aware of such schemes to generalize the training? Thanks,

Hello, did you find a suitable answer to your question? I have been trying something similar and would love some insight.

a policies trained for transferring a policy trained for one morphology to another probably won't work very well, unless the two morphologies are very similar. There are some work that tries to learn general controllers for different morphologies: http://mrl.snu.ac.kr/publications/ProjectMorphCon/MorphCon.pdf but requires training on a set of different characters.
