Hey all, working on another project that consists of modeling, texturing, rigging, animation etc. I just finished modeling and I've created the joint structure and parented the body sections to the appropriate joints (all rigid binding) and I'm having a little bit of difficulty setting up the Ik structure for the character.

My first problem is how do I change the way a joint moves so that it bends correctly. The pictures below show my problem. The knee needs to move like a human knee and it obviosuly isnt doing that.

Second, I'm not sure how i should set up the Ik structure for the arms, seeing as how the are a little more complicated (fingers) than the legs. Any suggestions and advice would be much appreciated.

Thanks all!

when u were laying out your joints u should have set them slightly bent toward the axis u want the ik to calculate from.

but u can disable the iks,
select the elbow [or knee joint] rotate them in the correct bent angle then right click on the joint and choose "set preferred angle"

then 0 them out again to default position then enable ik again
