rigging help

Quite a simple question, I was wondering if anyone could tell me how to rig this mech so that i can get hip/chest movement to make a walk cycle more realisitic.


More realistic than what? You could try changing the Chain Lengths on your IK Constraints, try AutoIK (make a copy of the original file so you can remove existing IK’s to test it without loosing anything if you don’t like it), or use CopyRotation Constraint(s) with limited influence on the hips to pitch the shoulders forward when the hips move.

Best of all would probably be an Action Constraint.
