Questions for initial pose

[zstky01]

Hello!

I am quite new to the MANO hand model, however, I wonder why the zero-pose input (45x0) gives a hand with bent fingers. In my option, the T-pose (where the pose vector are all zeros) should result in a flat hand, is there any trick or modify on the MANO model in the manopth layer? Or is the original MANO model have a bent finger on its "T-pose"?

Sorry, now I found the parameter flat_hand_mean…… issue closed.
