Nice workflow you have there!

This was the solution I came up with. Still refining it to have more
options per null but already using it in production.

Perhaps deform by volume?
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.
