Houdini ignoring node state and cooking everything April 11, 2024, 11:20 a.m.
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?

Retaining Pivot points from a Maya exported USD file Jan. 3, 2024, 11:14 a.m.
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 ?

Reload python plugin while developing? Oct. 17, 2023, 10:37 a.m.

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?
