I've got a muscle rig where the zCache is always emptying when returning to start frame. I can't find too much documentation on the limitations of the zCache feature. Could anyone give my some clues as to why the zCache would be resetting like this?
During the setup phase I never had this issue. The cache would reset when i changed a few attributes on ziva nodes but only then.
In my scene I have keyframes on
solver (tx, ty, tz)
solver shape (substeps, gravityY)
I started out with the muscle rig referenced but this problem led me to importing the reference (and deleting namespace). I also had connections from a ctl driving zTissue attrs (pressure, rest scale and surface tension envelopes) but i removed those trying to debug this.
I've also tried deleting the zCache and creating a new one with no avail.
