BOILING | Constraining POP particles birth position to deforming mesh

[neurostudio]

Hello there,

I am learning Houdini and I tried to apply the GeoBoil setup to a dancing humanoid. 

I am struggling to understand how to use attributes to constrain particles to their birth position on the moving mesh.

I have read plenty of related topics, but I honestly can't come close to any solution. 

I tried freezing the mesh with time-shift, scattering points, using scattered points to generate particles in the POPnet and then restoring the animation, but of course the particles remain in the position they were generated and do not stick to the surface.

I attached the basic setup file and  the .abc I used.

Thanks in advance!

Here's a different take on it. It seems like a nice case to use a custom solver

Thank you so much I'll go read some documentation and try to understand what you did there! will report back!

I understood how the attribute interpolate node works! Thanks. 

But still I can't implement it in my setup... #n00b

I figured it out! The attribute interpolate node obviously had to be placed after the popnet...
