If you're running below spec, (i.e. less than 12GB vRAM) you might consider using the OpenGL rop in the /out context for producing your flip books. There are controls on the rop to customize the quality. Another thing you can try with heavy geometry is to poly-reduce it or quad remesh it to a produce a lower primitive count. This reduction can help the view port. Also move your mouse over the 3D viewport and press the D-KEY. There are quality controls for the viewport under several tabs.

Maybe you could approach it as a rocket launch without flame or a helicopter downdraft expansion. There are a few setups on this site. Check my signature link.

Check out Mikael Pettersen's solution to this. He specifically did a tutorial on how to fix this issue. The HIP file is here:

Try another seed..?

You can just have a particle stop on impact. ap_pop_target_v00.hiplc

My first thought is the advected particles might be leaving the volume boundary. Try making the domain big enough to encompass the particles. They may be getting stuck because their velocity is converted to zero once they travel outside the advection domain.

There is an enhanced scatter and align node with additional features. https://www.sidefx.com/docs/houdini/nodes/sop/scatteralign.html

Here's the same scene after playing with a few parameters. Lower density and gravity. Also played with the glue release control. ap_hard_glue_wall_breaking-2_040325.hiplc

Maybe you could reverse engineer something like this. ap_hard_glue_wall_breaking_040325.hiplc

You can keyframe time scale. Applying more force will auto-break the constraints. ap_customForces_v09.hiplc

It's because everyone has migrated to Discord-based forums.

I'm not sure if you are referencing @ptnum inside your solver, but you can enable ID on the behavior tab and reference that instead (i@id). Make sure to turn off Kill Outside Volume Limits or your ID may change.

Funny you should ask. SideFX just released a tutorial on that topic. https://www.sidefx.com/tutorials/lops-for-solo-artists/

Here's a link to Mikael Petterson's water balloon tutorial file.

I followed Mikael Pettersen's vellum water balloon tutorial. ap_mp_vellum_water_balloon_041023.hiplc
