any update on an "ultra-kill" button? some heavy flip meshing services have locked most of the machine and its unclear if they will ever finish despite the cook tasks being cancelled.

Thanks very much for the indepth information
For more context on the use case, we would have a very long cache sequence ~3000 frames, we want to instance different cache frames onto points.
It is an alternative workflow for a simple crowd. We're trying this way as the SOPcrowdimport LOP was crashy and slow, and as we don't care about transitioning clips or the skeleton we thought this might be less intensive to render. It might be that crowds are the better solution here over value clips, but without any examples I can't be sure so I'm trying to follow the path of least resistance.
I'll see if the value clips method works well at scale and share any findings.
Cheers,
Luis

Hello, looking how I can instance animated geometry in LOPs. I think what I need for this is a value clip, so I'm using the new geoclipsequence LOP.
The only way I can seem to affect the time of the valueclip is by instancing references, then using retimeinstances LOP. Any other way seems to lose the 'value clip' pink text, and I could not get looping to work.
geoclipsequence must be cached (non timedependent) or the instances won't retime.
Not sure what the intended workflow is. Before LOPs, instancing animated caches with Packed disk sequence was very handy. It'd be great to have PDS sop import to LOPs to help show the 'correct' usd way.
Cheers,
Luis

Does this workflow support a sequence of vdbs? Plugging a volume LOP into the 2nd input it correctly shows it as a value clip, but caching it hangs.
Alternatively directly pointing to the vdb sequence the clip only caches one frame, and lists the volume filePath as a Default Value instead of Value clip. Not sure where I'm going wrong.

In simple .idx files, changing -0.07 to say -0.075 works fine. But in a larger preset file, changing the number of bytes per value corrupts the file and houdini doesn't recognise it. I'll try to narrow it down and upload an example that shows how an idx file that is failing as described.
Did you ever find a solution? Run into this now while trying to batch change parameter expressions over multiple idx files, presets are proving to not be as manageable as they could be.

Recently noticed houdini python will not catch errors in initialising a Qt5 / pyside2 python panel, making it difficult to debug code.
The only workaround I have is wrapping the culprit code in a try except block and printing the exception, not very ideal.
Anyone have a better solution to this?

Did you ever figure out a fix? Receiving this error when launching hython, it doesn't seem to impact anything for now but worried its a sign of something larger being broken.

rafalIs there any update on this RFE?
But it looks like you want to save images from MPlay, which is currently not possible. There is an RFE 32671 for it, though.
We'd like to add custom MPlay functions to make saving flipbooks into our pipeline easier, it seems there is no way to call MPlay hscript through the custom xml menus.
mtuckerAs there is currently no access to HOM through MPlay, can the HDK achieve this?
If the info you want to display is not accessible through HOM, you would have to extend HOM/hscript using the HDK
