Dear forum readers, I need some help with/in Maya. I have spent many hours searching the internet, but I without total success....

I am making a one-piece paper cut-out figure. I want to animate it in the end, but right now I need to get the movement right. I'd like it to move like a papper, kinda stff, and bending the paper in the joints. That cant be too hard can it?

I have made a flat polygon figure and a simple rig(skeleton). I have made a "rigid bind" between the whole polygon and rig.
But when I move the arm, the head moves too....
see image.

Is there a good guide/tutorial to help me understand this rigging on planar surfaces better?, or any other suggestions.

thanks for reading!

Hi there.
Youll probarbly have to repaint the skin weights. Or not, just checked the tools for riggid binding and theres no such thing... You might be able to edit every single cv weight by itself in window>general editors>component editor and check under riggid skin.

I think you can get away with parenting your geometry to the joints in this case. Just split up your geo in smaller pieces, f.ex. head part, left upper arm part and so on then parent the geometry to the correspondent joint.

hope that helped some

Thanks for your answer.

I have tried the Component Editor. It looks like this:

I do not understand what I can do in this view though...
I can see that if I select a joint in the head area, joint 6 shows. (and 18/22 for arms, 10/14 for legs). But I do not get anything to choose from.

I have also tried to start all over and make a rigid bind between the arm joints and the arm faces, and so on, but that results in the same thing.

It feels like I am too much of a beginner to even start to learn this.. (frustrated!).

Hi

Try Rebinding with smooth bind and set the parameter of the skin to just influence by one joint alone. You have to place the joints exactly over the folds, which is not in ur image.
