Cómo hacer para que los bones sean flexibles

[mundo 3d]

Hola compañeros, estoy haciendo un rigg facial, y la verdad no sé cómo colocar los Bones, para que sean flexibles (estirar y contraer). Hasta ahora el rigg lo tengo hecho, pero con Splines que hacen las veces de Bones, pero no sé si esto sea correcto.

Por favor si alguien sabe, se lo agradecería. Saludos.

Puse este código que hice en otro foro. A ver si te sirve.

-Select two points or more points and run the code below for creating a stretchy bone or a stretchy chain.

Fn makenubbone lastbone =
(.

Local pues = lastbone, transform[4] - Get the position of the last bone.

Local xdir = lastbone, transform[1] - Get the Vector of the x point.

Local startpoint = pues + xdir * lastbone, length.

Local endpoint = startpoint + xdir * lastbone.width.

Local nubbone = bonesys, createbone startpoint endpoint lastbone, transform[3] - Create the bone.

Nubbone.width = lastbone.width.

Nubbone, height = lastbone, height.

Nubbone.wirecolor = lastbone.wirecolor.

Nubbone, parent = lastbone.

Nubbone, name = lastbone, name + _nub.

Return nubbone).

Fn pointfilt o = (classof o == point).

If selection, count == 2 do.

If classof selection[1] == point and classof selection[2] == point then.

Thepoints = selection as array.

Thebone = bonesys, createbone thepoints[1], pues thepoints[2], pues thepoints[1].transform[3].

Thenub = makenubbone thebone.

Thebone, position, controller = position_constraint().

Thebone, position, controller, appendtarget thepoints[1] 100.

Thenub, position, controller = position_constraint().

Thenub, position, controller, appendtarget thepoints[2] 100.

Thebone, rotation, controller = lokat_constraint().

Thebone, rotation, controller, appendtarget thepoints[2] 100.

Thebone, rotation, controller, viewline_length_abs = false.

Thebone, rotation, controller, upnode_world = false.

Thebone, rotation, controller, pickupnode = thepoints[1].

Thebone, rotation, controller, upnodeaxis = 2.

Thepoints = selection as array.

Append thecnts thecnt.

Append thebones thebone).

Muchas gracias IkerClon, voy aprobarlo a ver.

Iker ya lo probé, men muchsimas gracias, eres un teso, en el tema. Pero tengo una pregunta, el max no tiene esa opción? Yo no sé dónde vi eso, o no sé si lo soñe o que.
