How to lock particles to animated object?

Well there are lots of ways of varying complexity.

But the simplest is to do your particle sim on a static object and then use the lattice set to point mode to get them to move with the body. It's not going to be the best way by far, but will get you started.

some other ways are:

1. create a primitive attribute with the primitive area stored inside before deformation (measureSOP does it) and just scatter points with the scatterSOP using that attribute. If You geometry deforms points stay consistent

2. scatter the points and store the primuv and prim id onto them, You can get the position on the primitive with a vopSOP (unfortunately it is singlethreaded)

3. Ignore the primarea inside the scatterSOP and it scatter the points the same during deformation

in the example I attached a trail sop to visualize that the pointdistribution is constant
