Hello guys.
I have a question about constraint inside Houdini.
I have a HIP file and I want to change constraint type from spring to glue and then glue to spring again.
With a simple SOP Solver I can make it from spring to glue constraint but for second part when I change constraint back to spring, I lost my curvy wall and position of the pieces of the wall back to their initial state!
More strangely, Houdini's spread sheet won't show changes in position of constraint points in DOP and just initial position shows in this case!
Can anybody help?
Really thanks.

You should use findattribvalcount VEX function because for each rbd packed object you have multiple point on cone twist constraint with the same name attribute.
In below link you can see an example to how to use this function alongside with findattributeval function.
http://www.sidefx.com/docs/houdini/vex/functions/findattribval.html [www.sidefx.com]
So:
-You need a point wrangle and connect main rbd packed object to first and constraint network to second input.
-For each rbd packed object iterate over constraint points and collect all attributes on them based on name.
-assign that to your main rbd object.
write the code and ask question if you have.

OK.
I've fixed it.
It is simpler than what you want but I think it will help you.
See attached HIP file.
Hope it helps.

Hello Behzad.
You should connect SOP Solver to third input of Constraint Network not to bullet solver.
After doing that, you can access to broken group and put constraints in or even bring them back.
You can iterate over all primitives and query for their specific attributes on primitive level.
Have a look at attached HIP file.

Hello.
I come across with a problem in Houdini.
I create a tool that subdivide my model adaptively with the help of for loop.
But the problem is when I use compile blocks to get the chance of multi threading, Houdini crashes immediately.
I'm on Ubuntu 16.04.
I have exact same problem with Windows 10 as well.
HIP file attached.
Thank you so much.
