tturner 0 Posted May 6 Anyone built multiple pivot mechanical linkages in Houdini? How would you IK this? I guess you could just mathematically constrain everything... but then you're working backwards from a known to make it work, as opposed to just arbitrarily connecting and changing pivots and lengths, and then seeing the result. I included a pic, not sure if it'll show up. If not, it's just an umbrella arm. Share this post Link to post Share on other sites
