View Full Version : Parenting wire deformers under a joint chain?

Hi All,

I'm working on a facial rig that uses a combination of wire deformers and a joint chain. I'd like my wire deformers to move with the main head joint, so I tried parenting the wires to the head joint. This makes the wires move along when the head moves, but it makes the deformation go all screwey.

I'm still pretty new to this, but I recall having these sort of parenting problems before. Is there a preferred method for parenting multiple types of deformers?

Thanks for the help.

For facial setups I usually use a seperate head geo and use a blend node always set to 1. That way the facial setup doesn't need to actually travel in space. You might consider doing that. Just a suggestion.

Best way to keep the wire deformers to follow the head Geo around is using RIVETS...

I believe the problem you are experiencing is the deformation order.
in your case you applied the joints before the wire deformer, right?
try this.
right click on the geometry, select inputs>all inputs
in the list that pops up, you have at least two objects, the skinCluster and the wireDeformer
drag the objects in the list so that the wire deformer applies before (under) the skin cluster.
probably and hopefully this will fix your problem.

and as XminusOne says, I also use one head that has the skin cluster attached to it, as well as one blendshape always at one, at witch I apply all deformations on the head.
