bits of mesh dont move with armature, but..

I have a mechanical (robot) leg that i am trying to rig. It is made up of the thigh, shin, and 3 pivots points (hip, knee, ankle). i also have a piston connecting the thign and shin.

as i have it now, if i grab the shin and move it directly everything works fine, but, if i move the shin by moving the armature, not everything moves as it should (if at all).

anyone know why it works fine by moving the mesh directly but not by trying to move it with the armature ??

Could you post a blend ? … I don’t quite understand how moving the mesh would “work fine” while the armature doesn’t work …

I am assuming that you linked the various mesh parts individually to a bone in the armature (your post makes it sound like you have multiple meshes for the parts) … If not, go into Pose Mode select the mesh and then shift-select the appropriate bone and Ctrl-P -> To Bone .

Ah, i know what i have done now.

Yes your right its made of seperate meshes, looks like what i have done is have some parts parented to other meshes and not a bone.

Everything is moving with the armature now, its not 100% correct as things are moving all over the place lol but i think im back on track again now.

Many thanks for your help.
