Animating a snowboarder So I am currently working on a snowboarder character and I would like him to do certain things.


I've been playing around all day with different constraints but I just can't get the desired result. What I would like it to do is when the spine moves along x axis, first the leg gets extended (totally straight), then as it pulls the board - the board starts to bend. Also I need him to be able to rotate the whole lower body, without an upper body, and be able to do the same board flexing thing. How can I do that?

Update
So I have been working with this armature, solved a few problems on the way, and new questions arose. The main one - is it possible in the "copy transform" constraint settings of the "board" bones limit "local space - local space" only to vertical axis, z in this case, and leave "world space" for x and y? So the board bones would be only flexible on the axis that a real board is flexible and I could easily apply rotations to the board? Or maybe I should look at this problem from different perspective and find some workarounds? Opinions appreciated. And thanks again to Italic_ for an awesome rig concept
I think you'd be better off using a character animation technique over a constraints-based setup.  Why not use something like Rigify to quickly animate the character, and then use a very simple rig to bend the board.

I first learned Rigify with this tutorial: Quick Rigging with Rigify

As for bending the board, simply make an armature along the board with as many segments as you want.  Then, parent with automatic weight the board to the armature.  If you want, you can set up an IK Chain to make the bending a bit more realistic.

Use the Action Editor to make actions for the board and the character, then put them together with the NLA Editor.
