Hi there,

Is there a way to track points to geometry, or as a work around to scatter points on geometry so that each frame (and as the object moves) the points are consistent in position and id?

An example might be if you wanted to stick sand on a character and keep it consistent throughout any sort of deformation or animation.

Thanks!

Rivet Object or Sticky Object.

Rivet Object is handy if you want to attach another object to some specific points on another object.

Sticky Object is similar but works on UVs which allows you to move your object along another object in UV space.

you can scatter points on animated geometry. Just un-check Scatter based on primitive area.

Oh. Right…. Mis read.

If you're character is deforming then you'll need to ‘measure’ your model in a static rest pose. Otherwise the points will jitter around since the scatter works based on prim area.

A Measure SOP set to area will do the trick, then turn on use Attribute.

Thanks all. The scattering with reference is working great.

As for sticking stuff to geometry, I'm avoiding that bullet for now. Also, my geo are all baked nurbs patches.

Thanks!
