Hi everyone,

I'm looking to animate a lipstick bullet while using the MPM solver. I want to:

- Animate the base points of several bullets

- Let the remaining points deform as the multiple objects continue to impact each other.

I’ve added "pintoanimation" to the base of a single bullet and that allows me to freeze it in position. But I'm not sure how I can update this animation and pin constraint over time for multiple objects. I believe I need to be controlling the points in DOPs section of the MPM Solver but that's a bit unclear to me.

Has anyone here been able to bring in SOP-level animation to the DOPs level MPM Solver?

Thanks in advance!
