Rigging detail-How will you do this ?

[tjnyc]

...i don't think it will be as easy as just parenting it to a bone....any suggestions ?


Not sure what you are trying to do, since your explanation seems somewhat unclear. If you want the shoulder piece to appear attach and not have to worry about adding unnecessary deformation calculation, you could create a bone with no influence at the end of the shoulder bone and parent the plate on to it and when at certain extreme poses you could rotate and/or translate the extra bone to simulate the plate moving. You can also automate the process with expressions, which is simple to do.

I've almost finish to model this character...and i'll start the setup tomorrow i think. Can't help with your questions at this moment but your thread would be nice as a WIP :wip: for us to follow. I'd certainly like to see how your project develops.

Grab your shoulder area with your hand and feel it as you move your arm around. This area where your plate is on, is pretty much stable and it doesn't change shape. You could just make the plate as part of your shoulder and make sure the bone deformations leave it as rigid as possible. Just an idea before you go lose few weeks of rigging over a small detail.

I found, it was'nt easy to explain in my native language already....but let me try again :blush: (and maybe sound more pathetic:p )

When i look a the left drawing (sorry for the mistake), it seem for me that the top and the bottom of the plate are attach to the leather. So when he 'll raise his arm, i would'nt like the leather to slide under the plate as it's suppose to be attach. Of course, the plate will raise with the shoulder (i mean on top of it), but in a rigid way. And because the plate is rigid, the leather will be deform.

The way you told me seem good for me. I just wonder if at the extrem of the plate, the leather will slide under it. If it's the case, than i'll add Endomorph for the shoulder "leather part" to make sure the junction between leather and plate move together.
And still, i think i will have to create Endomorph for wrinkles around the plates, especially when he'll raise his arm.

Like it could be with this kind of jacket:

...see the plate (1) is attach to the leather.

That's why i thought it was tricky, a rigid plate moving along with a flexible part.

Is it more understandable ?

But thank's Tjnyc and Dennik for the suggestions !!

It was a way to try to have an approach before starting.

Okay, I think I get it now. In that case I would recommend adding a weight tool like the sphere in the shape of the plate and parent that to the shoulder bone and set as a metaeffector to the jacket. The area underneath the plate which is weighted by the sphere object should deform properly without any sliding movement. No need for an extra shoulder bone.

if you are using LWput it on another layer, if you are using another program, as anohter object,
and parent to the bone of the arm,
