Hello. I tried to Google the question, looked up on the forums, read the documentation, played with examples but I still cannot find the answer.

I am working on a worm. It is procedurally animated through Point Wrangles in a SOP context.

The problem is that I want to use the SOP animation to drive the Rest position on the Solid Object in the dopnet.

So I am trying to find the right way to do it, I tried something stupid which is Tetrahedralizing the animated mesh at each frame, that does not work, as I get a different arrangement of tets at every frame, and the simulation cannot match the initial tets to the rest positions. I get an exploding worm.

What workflow should I use?

When they show transferring animation using Rest positions on tutorials or example scene files, what they do is distorting the tetrahedralized mesh. I already have the animated mesh that is my problem.

I attach the simple scene file. I wrote some notes if you want to have a look.

Thank you.

Your scene did not attach.
