Okay, now I don’t have that particular morph set ... places to check for more poses might be under “hands” or when you click [choose] the hand, over on the parameter tab there may be a slider/dial to make adjustments?
Sometimes there’s a readme or text file with a few instructions thrown in with products that may or not be of help. [found by manually poking through the folders looking for them]
If there’s no help there; the only thing I can think of quickly would be to dial the morph out when doing closeups of the hand.
Maybe somebody who has those morphs will chime in.
