I'm starting a thread here about how the discussion was already initiated here - https://yl2-cloud.appspot.com/suggestions/69
asked me to close pictures of which the joints could perhaps do with being a little fine tuned, Well, maybe the team can think of something else?!
Thank you for highlighting this!
Your attention to the feet has made me and odes to discuss this a bit and we've agreed that we will add a extra bone, dedicated to the ball of the foot for better deformation for when characters stand on their toes plus a overhaul of the skinning of the feet overall. I will do these improvements along with my content updates
For the forearm deformation - this will be improved upon when the first interaction build has been released with a more improved and in sync driver that will increase the fidelity of the flexes.
