Query on Ribbon set up

[abhilashsrinivas]

Hi...I have some queries abt rigs...kindly help me in the same...
I have heard about a rig having Ribbon spine..in maya.Can anyone help me by sharing their views on this, as how is this ribbon spine different from other spine rigs and wht are the advantages and disadvantages of it...
can Ribbon setup be used for hands and legs..?

Wht points we need to keep in mind to make a rig for a feature...

Looking forward...

Ribbon Spine is a advanced method of rigging the spine so as to get better deformation in the spine part then what is achieved with ik spline.It works by attaching joints to follicle which are attached to a nurbs plane which is called ribbon through the use of pointonsurface node , and works through the use of point and aim constraints.

And for the other question it can be used in hands and legs as well using the idea used in spine part.

Hi Abhilash. I am Rahul. You can use ribbon set up in spine, hands and legs. Ribbon set up is used on most cartoony characters, like in the hand to get a lil' arc in the action.
When you use ribbon setup in spine then there will be some advantages and disadvanages.
Advantages are like, you can rotate any joint at any value in the ribbon setup which are connected to character's spine mesh that's what u can not do on simple IKspline rig coz' after putting iksplineHandle, rotations of the joints in hierarchy gets locked. And also the ribbon set up joints stays at there places on the nerb patch on the stretch.
The disadvantage is you don't get the spine rotation about z-axis which we get in normal rig by rotating soine controller about z-axis. And that's why ribbon set is not prefered in spine. But u can use it widely in hands and legs.

hi abhi,Ribbon spine bone is used for better deformation.in the old method of spline ik when it's rotated ,then the mesh is a little scaled.in this method nurbs surface is used and hair folicals is used.it's the best method of rigging.
