Hi
I have a character rig, and have been trying to rig some eyebrows to stick to my deforming mesh (facial expressions with pose morphs, and regular joint rig for body movements)
My strategy was to constrain nulls to my body geo with xpresso point nodes, the using the tracer object to connect them and then a sweep to create some eyebrows. This does what I want it to, constrains the nulls to the deforming geo nicely (no lag) ...BUT the lag on the sweep / tracer is significant . I have tried shift priority tag, increasing my xpresso priority, changing to generators etc...but to no avail.
The nulls seem to follow along without lag, its the tracer / sweep that seem to lag.
See attached file for a simple animation and pose change.
If anyone has a better way of sticking eyebrows then happy to try, or any advice on this would be appreciated.
(I also tried a surface deformer, but this lag was worse seemingly, and slower)
Thanks!
