Hand rig problems

(arachai) #1

OK so I am trying to rig a hand. Simple character so I figure simple rig…wrong. when i add my constraints, the bones do weird things. for one, the whole arm rig moves when i put an IK constraint on the hand. (see pic) when i put an IK constraint on the thumb null bone, the thumb rig moves. then when i rotate or grab the thumb IK bone its as if the rig is crashing!! can anyone tell me whats going on?!

Hi Chris, everyone tries to rig differently for their own desired results. Here for example is one way to rig an arm - unfortunately this documentation is not complete. Another way to learn to to look at / or borrow rigs made by others - you can find enough here

My first instinct would be to make sure the lower arm is yellow [IK solver] as most rigs work that way…

…hope this helps…

thank you patdog. that was my problem. i added an IK solver constraint to the loarm bone and BAM!! it works. Thank you for pointing that out.
