We've gone back to rendering in Houdini 19.0 for now, which is an awful solve even short-term as the resolver format changed between the two versions so we're being forced to flatten scenes down before sending them to the farm.

It's definitely frustrating that multiple studios have flagged this for multiple renderers and yet no one seems to have any ideas.

Personally I feel like if the same RenderMan version stalling in 19.5 and not in 19.0 that puts the ball in SideFX court but ultimately we just need it fixed :\

Agree ^

Does someone has found a solution to husk getting stuck. I am having this problem when trying to render volume.
I have tried with all the Houdini 20 update. Now I am using 20.506 and I still have the problem.

https://www.sidefx.com/changelog/?journal=20.0&categories=58&body=&version=20.0&build_min=582&build_max=582&show_versions=on&show_compatibility=on&items_per_page= [www.sidefx.com]

There was a hanging issue with volumes fixed in 20.0.582 (which 20.0.506 seems quite old).

We have tried to reproduce the issue with husk hanging when rendering but without any success. If some renders complete, but take longer, then, it sounds like it might be something other than a hanging issue. We've also been unable to reproduce this.

As a note, if you're rendering on Linux or OSX, you can send husk a USR1 signal, which will cause husk to save out a snapshot of the current state. Not sure if this might help.

It is something we're continuing to look into.

The update has resolved the problem and now volume for me are rendering fine.
Thanks

I am still running into the same issue as originally when I started this thread. I can see some comments about volumes being fixed, but I just want to iterate that this is very much still an issue.

1. The problem is that when launching a task via Husk it gets stuck after a certain random frame and the process does not "Complete" and therefore Husk is unable to move onto the next frame. Again this is random. It can occur on frame 1001 and just as likely on frame 1017 for example.

2. We have noticed that the problem seems to occur more frequently (but not exclusively) on larger scenes. E.g many dependencies or larger polycount scene. I will try and flatten down a scene where the issue can be reproduced and send it across to SideFX, but honestly this can be very difficult as often the layered nature of many USD files can be difficult to flatten down and work 100% the same as the non flattened version. The scene I am trying to render now have over 25,000 descendants for example, which is made up of 1000's of .USD files on disk.

3. When SideFX says they have investigated the problem and can NOT reproduce the issue, I would urge SideFX to share the details or share their scene so we can see what has been tested and how. A sphere in a scene with some lights will most likely work fine, it is when the scene complexity starts to rise the issue occurs.


I launched a render again yesterday and was rendering for + 10 hours. It rendered 1 frame and I got a .exr file on disk. However the "task" never completes and husk continues to use 4-5% of my CPU and keeps hanging unable to move to the next frame. I launched the same job this morning and it then got stuck on frame 1009, so again random. I am on Houdini 19.5.640, RenderMan 25.2, Windows 11.

I have the same issue, not sure if this is relevant but I recognized it more often when I added cryptomatte. anyone find a solution? thx

houdini 20.0.547 and karma

I'm having the same issues with USD renders "Hanging" on random frames. I have a fairly complex scene but have also had the issue on fairly simple scenes. The only solution at the is to constantly baby the HQ render farm and restart and render that looks to be hanging.

Which is incredibly painful.

Houdini 20.0.653 & Arnold 6.3.1.0

Unfortunately I do have the same problem.
Houdini 19.5.640 Py3.7 on Windows 10 Renderman 25.2

In 99 percent of these cases the render hangs after ALF_PROGRESS 100%, but sometimes the following error message appears on those stuck renders.
Hopefully this helps with finding the issue?

Thank you very much.
Martin

I have the same or simular issue that I can send Jobs to the farm via Deadline, but it looks like the render progress hangs. Even if frames are rendered, he is not finishing the task and continues with the next frame.

Houdini 20.0.688 and Karma. Submitted via Stage Editor and USD Render Rop. Even if you do it via OUT/ Fetch and Deadline Submitter Node I have no success. But I also have Cryptomattes active.

Cheers,
Kay

I'm having the same issues on Apple Silicon, Houdini 20.0.724, and Karma - husk could get stuck after a few frames, or a few hundred, and continues to consume CPU. I've let it run for hours, and it never finishes.

Cheers,
Tim

Any one find any solution?

Thank you very much and sorry for my english...

August 2024 and I am still running into this issue. Did anyone find a solution?

Tonight when trying to get renders out, I get the following error on frame 1002 and it was hanging. Frame 1001 went through fine.

Unable to write to image: husk:null_raster_part
Error: Failed to create file "husk:null_raster_part : Permission denied".
R56011 {WARNING} 41 objects had displacement <10.00% of bound. See statistics for details.

anyone seen this before?

I'm running into this problem using Karma CPU on MacOS, so probably not an issue with your GPU (or not the same issue).
