Hey all

I think I may have found a bug but I'm new to Linux so wanted to make sure I wasn't crazy before reporting it. I have a scene that works fine in Windows. Everything is good. In fact, it also works fine in Linux.

I'm loading in an Alembic camera into the obj context and everything works great. I'm then importing that camera into a LOP context withe a sceneimportcameras node. Again, on Windows, everything works great.

However, when I go into the LOP context, that same sceneimportcameras node throws a python error and suddenly the camera won't work. This is the error:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/opt/hfs21.0.596/houdini/python3.11libs/husd/pluginmanager.py", line 79, in __init__
PluginManager.__init__( self,
File "/opt/hfs21.0.596/houdini/python3.11libs/husd/pluginmanager.py", line 23, in __init__
self.myPlugins = pluginutils.runFunctions(
^^^^^^^^^^^^^^^^^^^^^^^^^
File "/opt/hfs21.0.596/houdini/python3.11libs/pluginutils.py", line 225, in runFunctions

module = _cacheLoad(filepath, silent=True)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "/opt/hfs21.0.596/houdini/python3.11libs/pluginutils.py", line 42, in _cacheLoad
obj = loadModule(filepath, silent=silent)

File "/opt/hfs21.0.596/houdini/python3.11libs/pluginutils.py", line 69, in loadModule

File "/opt/vray7.20.10_houdini21.0/vfh_home/husdplugins/shadertranslators/vfh_usd.py", line 15, in <module>
import vfh_py
ImportError: libhboost_python311-mt-x64.so.1.85.0: cannot open shared object file: No such file or directory

Then, another one comes up:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 'theTranslators' is not defined

This just repeats in perpetuity.

I have package files I've setup to redirect my file paths between Windows and Linux, so I thought that maybe that was it. However, when replacing the Alembic with native Linux file paths, I still get the issue.

It's worth that that the Alembic loads and works fine in the object context, but as soon as I switch to LOPs that's when I start getting issues.

I'm running an Arch distro called CachyOS. So far, everything has been fine except for the incredibly obnoxious middle mouse issue everyone else seems to be having.

That looks like an issue with Vray for Houdini where it can't find a shared library. I would message their support team and see if it's a known issue.

I wondered about that too, but what's weird is I'm not using V-Ray in this particular script. I was just trying to import an Alembic camera into Karma/Solaris. I'll post on the Chaos forums too though. Thank you for the response!
