About hand pose

I got the pose of hands from the output of the demo code. When I apply the pose to an avatar, its hands have weird pose. I guess it is related to the parameter "flat_hand_mean" of the SMPLX model. So I am wondering if the Hand4Whole model is trained with flat_hand_mean=False? If I would like a initial "flat hand", should I train the model from scratch?

Yes it is traiend with flat_hand_mean=False, and you can check here to get that

God, I Got the Same isssue, i think we need finetuing model with flat_hand_mean=True Flag

you can simply add subtract the mean pose from the current estimated hand pose if you want some hand pose with flat_hand_mean=True

mean

thank you so much for reply, you meaning finetuing model is not actually necessary ? we just need to subtract the mean pose ,then we can get the right pose ?
