Hi

I have a object as Picture attach in bellow.

This Head Bone Point number will changing in every frame
sometimes 5001 sometimes 5100 sometimes 5500 sometimes 4500

I would like to know how to make this animate bone fix in a Point number like 5000, so that i can join the muscle node to the point I want. like image call “sendpix1.jpg”

if not, the muscle that refer to point number will jump to the place i don't want it to join for example as the image call “error.jpg” attach bellow

PS: polyreduce SOP & rest position SOP is not the solution

thanks

You'll have to post the hip file so we can take a look. If you are using a static model the point count shouldn't change.
Are you using blend shapes to animated the skull?

One thing you can try right away. Lock the File Sop node that you use to bring in the skull model on frame one.

hi , thanks for reply

the original hip file was too complex to see where is the probelm

so i make a new and simple one refer to the problem i face. bellow is the attachment.




as you see , there is a muscle joining refer to 2 input primitive, and everyframe bcs of the primitive number is different, the muscle is also jumping to another position, i would like the muscle stay in the same position but also reflect by the object changing everyframe.



thanks
