Rigging a Piston in Blender 2.5

In this Blender 2.5 video tutorial we relook at an old topic, showing how to rig a piston for automatic deformation that follows the mechanical arm.

This tutorial covers everything from the initial armature creation to setting up the constraints and assigning the vertex groups.

    Hi!
    Thx for the great tutorial. I am currently trying to rig a similar hydraulic setup and your ideas on the piston alignment really helped.

    Now here is my problem:
    The rack and pinion setup for the bucket on “real” excavators uses different lengths. The idea is to make the bucket go all the way around (for people interested in technical details^^). The trick with copying the angular movement for the lever atached to the piston won’t work there. Has anyone encountered and solved a problem like that? I have been playing with inverse kinematic solving, but iit never quite worked out :(

    Regards,
    kai

    Yeah, I dunno. I paid nothing for this tutorial! So, thank you.. but I would suggest, just trying to be constructive, that you edit your mistakes out of the final video and take a deep breath before moving on. I’m a little dumb, so maybe others didn’t have this problem, but when you got to apply the mesh you started moving waaaay too fast right after you fixed the problem with your old vertex groups.

    Esp. where you started explaining the bone/weight mode/pose yada yada. I’ve been sitting here rewinding and playing over and over.. my ignorance is surely to blame, but that whole section is jumbled by you fixing your mistakes, teaching a trick, and moving on with the work.

    I still have not managed to replicate what you’ve done there.. but I will keep at it.

    Otherwise, very nice tutorial, thanks.

    Hi I have been using your tutorial to try and make a working suit of armor. What I did was use a human from makehuman and then add on to the already existing bones from the makehuman character. For some reason when I set parent to Armature deform with empty groups it only transfers makehuman bones and not the bones I added to it. Can anyone tell me why this is happening and how I can fix it.

      You need to make sure ‘deform’ is checked on each bone and the bones are all under the same armature.

    hey Johnathan i loved the tut but i am really new at this and i am having a problem making the hinge work right and it looks like the model that i have and the one on the video are different and i am having truble fixing it could you drop me just the bucket and hinge set up and i should be able to get it to arm 2 thanks matt.

    Jonathan,
    Love the tut.
    Was/is there a tutorial on modeling the piston and/or the arm?
    It feels like I stumbled into the middle of something.
    All the pistons are in a vertex groups, and for the life of me I can’t remember seeing you use them on tutorials here on BlenderCookie.
    Of course that could just me.
