With this setup I demonstrate how to drive the influence of an attach to geometry constraint using and attribute on the constraint geometry. As a bounce the glue constraint strength between the grain points are also being driven by a gradient.

Really nice resource trove you’ve got here. Saw your tuts on Vimeo. Just dipping my toes in Houdini waters and I love it, you just helped me out solve the flickering problem on the surface mesh 🙂 (wrong article but skrew it!). Thanks for the info and keep up the good work!
Thanks Oliver! Mesh flickering the frustration waiting at the end of every sim 😉 . Glad to help!
