Vray and Arnold not loading/working together within houdini/solaris.

[lu_xing]

4n7 May I ask where should I place this piece of code? I'm a newcomer to Houdini, so could you please provide more detailed instructions? Thank you very much.

lu_xing all recent nightly builds contain the fix, you don't need to adjust anything.
As for the original question - installer installs vray_for_houdini.json file into the default Houdini packages directory (the one you are choosing at the Advanced installer page), you need to adjust this file.

Dear lu_xing, hello.

If you open https://nightlies.chaos.com/#/vray6houdini/nightly and you don't see builds there, please send me in a private message the email that your licenses are associated with.
With the e-mail used here I am not able to find the needed information and to request the access.

Waiting for your answer.

IGNORE THIS, It is working....
-----------------------------------
Dredging this back up again as I'm now hitting the same issue with 20.0.547 py3.10, latest nightly and HtoA 6.2.5.1

This maybe a nightly thing but the pythonlibs3.10libs (or 2.7/3.9 etc) isn't in the vfh_home folder, is this in a different location now or will this be re-introduced in a stable release? I tried grabbing these libs from an older stable release but hit the same error

previously the fix was adding this

{ "PYTHONPATH" : [
{ "method": "append", "value": "${VRAY_APPSDK}/python" },
{ "method": "append", "value": "${VFH_HOME}/python3.9libs" }
]},

but now the packages.json includes the dso path

{ "PYTHONPATH" : [
{ "method": "append", "value": "${VRAY_APPSDK}/python" },
{ "method": "append", "value": "${VFH_DSO_PATH}/python" }
]},​

this looks like the same file as before but doesn't seem to work
C:\Program Files\Chaos Group\V-Ray\Houdini 19.5.605\vfh_home\python3.9libs\vfh_py.pyd
C:\Program Files\Chaos Group\V-Ray\Houdini_20.0_d5d1f6e_22645\vfh_home\dso_py310\ 20.0.547\python\vfh_py.pyd

In Houdini the path is

PYTHONPATH
C:/Program Files/Chaos Group/V-Ray/Houdini_20.0_d5d1f6e_22645/appsdk/python;C:/Program Files/Chaos Group/V-Ray/Houdini_20.0_d5d1f6e_22645/vfh_home/dso_py310/20.0.547/python;C:/rez/Scripts;C:/Users/antg/AppData/Local/Programs/Python/Python312

Thanks
Ant

EDIT: If I remove the material collect node or arnold node from the materiallibrary node then the vray material is restored, not sure if I'm missing some workflow option here

EDIT 2 : IGNORE THIS, IT WORKS, I think maybe the arnold shader is overriding the collect, I'll have to investigate, but this works fine again. THANKS!

Thanks for editing that it is now working : )

Enjoy your work!
Test also the recent improvements in V-Ray 6 Update 2.
