Hello

 

I am pretty sure you can do this but I cant make it work....

Basically I want to make a mechanical extension arm kind of like this

http://cache1.asset-cache.net/xc/86437837.jpg?v=1&c=IWSAsset&k=2&d=2AC75F6FAA20674CB5E47545F000B36A2CDFD24D7B7E4E94C7BBCF18EB30ABE8

 

But without the boxing glove....

 

I have been messing around with Pickwicking the rotation to various other elements rotations and parenting all the seperate elements together

but cant seem to make it work, any help would be much appreciated.

 

Thanks

 

Matt

    That's a rather broad question. It'll be easier to help you if you ask specific questions and show what you've tried already.

    Assuming you have all the pieces parented together in two chains where the first layer in each chain has the anchor point in the middle, the others have the anchor point where they attach to their parent, and one chain is parented to the the other, the two pieces that attach to the main parent get this:

     

    -parent.rotation*2;

     

    everybody else gets this:

     

    -parent.rotation
