Hi everyone!

I'm setting up an HQueue setup to use my 2 machines but I'm encountering some issues when 3rd party renderers are involved:

Everything works fine with Mantra, I'm able to submit jobs and split the load between the 2 clients, BUT as soon as in the project file are present 3rd party renderers nodes the job fail.

That happens even when the HQueue Renderer node is pointing to the Mantra ROP.

At first it wasn't recognizing the nodes, so I added the Environment variable HOUDINI_PATH to the HQueue Renderer node and that seems to have fixed that part of the issue (found out about that "fix" here: https://tokeru.com/cgwiki/TopsTractorDiary [tokeru.com] DAY 3 insert).

Now the job fails with this error log:


Can anyone help me fixing that?

Because having to remove every single Octane node from a project to be able to render it using HQueue seems not the best "workaround".

P.S. I'm on Linux 22.04 LTS, Houdini 19.5.569 and HQserver/client 18.5.696

Thanks.

Hi!

I'm encountering a similar error while trying to use HQueue to render my scene on 2 machines:

I't works fine with Mantra, but if the scene has some 3rd party renderer nodes (Octane in my case) HQueue starts complaining. Even after defining.

I had to define an Environment variable in the HQueue Renderer node to point it to the HOUDINI_PATH, that way it recognize the nodes (saw it from here: https://tokeru.com/cgwiki/TopsTractorDiary [tokeru.com] DAY 3 insert); but still if I submit the job I get this error:

The Houdini 19.5.569 environment has been initialized. Can't open dophints.cmd Traceback (most recent call last): File "/opt/hfs19.5.569/houdini/scripts/hqueue/hq_make_ifds.py", line 1, in &lt;module&gt; import hqlib File "/opt/hfs19.5.569/houdini/scripts/hqueue/hqlib.py", line 20, in <module> import hqrop ModuleNotFoundError: No module named 'hqrop'
Any chance someone could help me with that?

Hi all!

I'm tring to recreate the tutorial made by Entagma on how to melt objects (tutorial: https://www.youtube.com/watch?v=B3W-S0EW9xw&t=1146s) but I'm encountering an issue:

It all works fine at a low resolution (particle separation of > 0.02), so the mesh is "fixed" untill it reaches the desired temperature and then it melts; the problem emerges when you try to go higher in the resolution (p. separation < 0.01).

The mesh melts correctly but it isn't "static" up to that point, instead it sort of collapses like the viscosity isn't high enough anymore...

I've tried pretty much anything but nothing seems to work, the only solution I found was to use i@stopped = 1 when the temperature is < 0.1, but doing so isn't optimal because it prevents the action of gravity on the particles not "awaken" keeping them suspended mid air if the one belows them have melted.

Reading the comments under the tutorial and on their fourm seems that I'm not the only one with this problem.

You can download the file directly from the tutorial and try to increase the resolution.
