Hi

Does anyone know how can I add a hard constraint between two or more particles ? exactly like RBD objects but it should be work for POP solver.

I prefer do this via custom VEX codes for manipulating P or V.
I tested different methods such as using verlet equation and control distance between particles without any good result ,Seems like this method should be use for Wire or cloth simulations which has stiffness But not for Hard constraint !!!



Thanks

Hello dear Sadjad.
Did you check this tutorial?
Pluralsight - Creating Custom Houdini Solvers with VEX Wrangles.

Hi my friend

unfortunately no , is there any method for doing that ?
not using RBD constraint or any native Houdini constraint tools ?
I want to doing this just with controlling P or V attr from VEX .
If yes ,So I should check this tutorial

Mentor of this tutorial creates sticky constraint fully in VEX he also learns how to break constraint and I think this is most nearest available tutorial for your need.
I can send project files if you want via telegram because it's big.

Here is HDA:
