Oi Tiago
Há uns tempos fui ao teu site para ver o que andavas a fazer mas estava em
baixo.
Sempre foste para a Austrália?

Eu tou pela Illusive mas cheio de vontade de bazar para algum lado mais
interessante.

No processo também pensei no que sugeriste de usar geomatria, NURBS, para
calcular os weights mas acabei por me ficar pelo mais simples.

Pah eu tento sempre implementar ideias que tenho e no Softimage o caixote
de ferramentas é consideravelmente maior e mais interessante. Ainda me
lembro quando me falaste pra mudar pra XSI ;)

 This doesn't deal with weight though but can be flexible since you can
 interactively mod the radius on the volume deformers.

 Subject: Envelopes, Weights, Deformers and setting them up.

 Hi
 We use Species here for ease and speed. So the head and jaw have their
 deformers, and the facial expressions are done through Shapes on a FaceRig
 panel. For some time now the animator wants some additional Facial controls
 so he isn't restricted by the range of the shapes. And he wants something
 that does not turn into a cumbersome task given the revisions/iterations
 over an asset. I'm fairly new to Softimage and these were the approaches I
 went about:


 Doritos
 I had it setup, just one thing that is dragging the process; Envelopes
 are generated by distance but there's always normalization. So if I want
 them to just have a straight spherical falloff into black I can't. Or even
 to falloff into another dummy null weight, I can't. So I had to paint,
 around the ears, on the top of the head and sides, neck, etc. I was trying
 to minimize paitings so iterations on a model's rig can be faster.
 I could put an inplicit per Derformer set on Bounding Volume > Limit.
 But it's an abrupt cut off.


 Deform by Spine
 Creates the falloff I want from the curve. I like the "drawn"
 deformations it does on mouth and eyes. I do an operator per curve, since
 the combined weights of several curves seems wonky. The downside seems to
 be that I can't transfer them with GATOR. How would you come about to
 transfer Deform by Spine between objects to save time?


 General Concerns.
 I come from Lightwave and Envelopes to me seem to be like a box of
 weights that are usually normalized. I see that deformers like Cage, Spine
 also generate such box of weights, but they don't seem to be handled as
 envelopes.
 How flexible and manipulated can be weights and the underlying
 connections of Softimage between the mesh object, the weight, the control
 null and the deforming operator?? Seems to me that such weights don't exist
 without the deformers.

Cool.
One interesting solution too would be to use meshes instead of nulls. we
used that in production and it worked quite nice for body parts, but it
surely lacked the speed and procedural behaviour of your solution, which
works better for face deformers.

Heat algorithms tend to be very usefull too, in situations where the mesh
folds a lot.
