Deformers only appearing on one frame

I’ve been working on building a rig and for some reason none of the deformers actually show up past the first frame. I’ve extended the exposure, I’ve copy pasted the first drawing, I’ve tried changing which deformation chain it is attached to but nothing works. If I go past the first frame all deformation tools simply disappear and cannot be reactivated as though there are no deformations attached to the drawing in the first place.


Are you sure that the substitution drawing used at frame 2 is the as at frame 1?

Deformation chains must be assigned to every substitution drawing separately.

So, lets’s say, your deformer is assigned to substitution drawing “1”. If frame 2 contained a duplicate of drawing “1” (e.g. “2”), no deformer would be assigned to it by default.
