hi koots!
thanks for the reply. no i did not download any video tuts from here. i dont have visa card to buy vip points so... ;\
i used some really basic IK setup with only one goal object for one leg. some rotation limits and... that's all. ohh... one bone in the higher part of spine has a target item. the target itself is traveling in a straight line and thanks to this i did not have to animate the upper body at all.
