Houdini 19 installer issue

Installing VRay for Houdini19 caught me out.

When I tried to start the VFB I got the following error:



I wasn't really sure what to do.
Luckily I checked the VRay license server settings and discovered that again, the VRay installer had set my license server ports to 0

This is obviously a problem.
The second problem is throwing an error like the one above for a license issue.

I suspect you might be making a lot of support work for yourself.

Dear Dubbie99, hello.

Thank you for the feedback.
I was able to reproduce it, but this is not Houdini 19 related at all.
Also it is pointing to a custom problematic setup.

I remember that you had written about other license related stuff and a ticket to Tech Support was opened in our system.
There you described that with every .exe installation Chaos License Server is installed even when is chosen to use the already installed one. But this is not happening.
By trying to reproduce this I received the error from your screenshot above.
1. Stop the License server (as expected localhost is refusing to connect = as proof)
2. Install V-Ray once more, choose to use the available License server
3. Open Houdini (not only 19, but any build), try to render and receive this Instantiation error

If you go to Start menu > Start Chaos License Server Houdini + V-Ray work together as expected.

In conclusion, you are experiencing issue with your custom setup and this could be solved if you provide us more information or continue the communication with our Tech Support team.
Together for the win. Seems all is connected and should be solved to avoid further issues.

Best regards,
TS

Hi
The problem is with this file: vfh_rop.py in C:\Vray\vfh_home\scripts\python\vfh

in both return the same error in vfh_rop.py
vray_adv_51020_houdini19.0.383_2f70004_18136
vray_adv_51020_houdini19.0.383_383135b_18167

Error running Python dynamic menu strip script:

Note: Already reported this issue in Discord !

As far as I know TS, I don’t have anything custom whatsoever. I use the standard vray installer. My colleague on a different workstation had the same issue. What information can I provide you to figure this out? Sorry I must have dropped off the communication last time with the tickets. I’ll dig up the email tomorrow.

AttributeError: 'NoneType' object has no attribute 'instances'

This means that plugin was not loaded at all.
Make sure Python version in the installer is correct (19.x is Python 3 by default) may be automatic detection failed for some reason.

Same issue with license port set to 0? Well, we'll just have to fix this...

Yes, the port had reverted to zero for him as well.

Dubbie99, thanks for the additional information.
It looks like not only one thing could cause this error.

In addition, elrachyd, the described from you is happening only with the installation from .zip.
Could you confirm that, please? It will help us a lot.
Thanks in advance.

Next build will contain better error message for such cases.

[tsvetomira.girginova]

elrachyd, to solve it quickly, please do the following:

1. Go to vfh_home in your downloaded folder extracted from .zip
2. rename dso folder to dso_old
3. rename dso_py3 to just dso

Run Houdini 19 and confirm that V-Ray is loaded properly and no error messages are seen.
Just tested, should work for you.

Hi
Yes I'm installing it from.zip, Following your instructions I get another error:
Error running Python dynamic menu strip script:
Traceback (most recent call last):
File "<stdin>", line 6, in expression
File "C:/Vray/vfh_home/scripts/python\vfh\vfh_rop.py", line 203, in vray_rops_as_xml_menu_items
return menu_items()
TypeError: 'list' object is not callable

[bdancer]

Line 203 of vfh_rop.py is "return menu_items" I'm not sure why you have "()" appended....
Anyway, tomorrow nightly will contain new .json file that will support both py2 and py3 Houdini builds without any modifications.

[elrachyd]

Using the install solve the issue

[tsvetomira.girginova]

Yes, the issue is isolated to .zip only, but tomorrow they both will work flawless.
Thank you for reporting.
