Hard Constraint with SOP solver problem

Recommended Posts

Hello people!,

I'm new to Houdini and just started to learn how to do the simulation of the helicopter crashes by Steven Knipping Applied Houdini series.
I had a problem working with the Hard Constraint with the SOP solver.
Before creating the SOP solver for the Hard constraints, I had make sure the hard constraint network is functioning.
 

Here's a video of the simulation that the hard constraints are not working anymore

|| Sop Solver

I used this wrangle as the tutorial suggested but it seems to smashed into pieces and not sticking together, the hard constraint is hardly working.

so then after I had did some research and found out some people actually uses && instead of ||.
So I try changing it to && and the simulation seems to work! The hard constraint seems to be working!! The pieces all sticking together.

&& Sop Solver

I'm afraid I might be going the wrong direction, I will post my file here so anyone can take a look at it and if there's something amiss? I tried solving for 2 days but it seems to take a toll on me haha.
Thanks!!
