I had a similar issue.
When running a dopnet live the sim is running fine.
When caching that sim, some of the upstream nodes where unnecessarily cooking every frame ( even if time independent )
The problem with this bug is that is hard to reproduce because the same network sometimes bugs sometimes not. ( ie. after relaunching Houdini)

I had no plugin installed locally just pref files that gets created automatically.
Deleting the folder content solved the issue.

I wonder if anyone from the staff could give us a pointer on what kind of file could cause this instability?

I have a related issue,

I'm exporting my geometry from Maya as an USD file. The geometry is made of few primitives with specific pivot points ( a few boxes with pivot at one of the corner )

I want to process( ie polyreduce ) and export the geometry as USD from Houdini retaining the original pivots.
Any directions would be appreaciated!



1 - In the scene graph details I cannot see the "xformOp:Translate:pivot" attribute as FoamFX is.
But if I reload the same USD in Maya the pivots exist and are correct.


2 - In USD ROP Lop (usd_rop) I cannot find any option regarding the pivot. Am I missing it? Is there a special attribute that I can use to override it ?

It's good to remove that reloading for the production version.

Does it cause overhead to have it on for all custom HDAs that requires it?
( assuming you are reloading relatively small modules )


the HDAs' Python Module gets loaded when starting the Houdini session and when clicking a button that calls back a function of that module. Correct?
