Vray version?

[woytha]

Excuse me, but how can I find out what version of Vray is loaded?
I tried to install the nightly build now and if I go to "about Vray" there is no info. There is no info about the version in the dialogs, or console so I am not sure whether the update was successful...
Thx

In a python shell you can enter

import vray
vray.getVrayVersionDetails()

May be you are running python2 V-Ray on a python3 Houdini, or opposite. Can you share what is your Houdini and V-Ray installation filename.

Dear woytha, hello.

We will investigate this issue further. For now it is listed in our system with HOU-2569 number.
I was able to reproduce it today on Linux.

As I see you are using Windows, but please confirm for extra clarity.
Also will be helpful to share - for which Houdini version was the nightly build and was it from 14.05.2021?

Thank you in advance.

Enjoy the weekend,
TS

Houdini is 18.5.351 and Vray file is this one:
vray_adv_50050_houdini18.5.351_9ea6717_13033_windo ws

Thanks!

Thank you for sharing.

This is a stable build from 12.04.2021. I have tried now (both with .zip and .exe install) and wasn't able to reproduce it on my machine.

As a last step, please confirm that your Houdini build is using Python 2.7.
The easiest way is to open the Python Shell where it will be displayed.

Waiting for your answer.

Yep

Python 2.7.15 (default, Mar 10 2020, 16:25:26) [MSC v.1916 64 bit (AMD64)] on win32
Houdini 18.5.351 hou module imported.

Great.

As I see you are using zip install.
With Houdini closed please follow these steps:

• open vray_for_houdini.json from C:\Program Files\Side Effects Software\Houdini 18.5.351\packages
• replace the 10th row ({ "PYTHONPATH" :...) with

  { "PYTHONPATH" : "${INSTALL_ROOT}/appsdk/python27" },

• Open Houdini and check out the About V-Ray window

Give us feedback here.

This code was already there...

In the installation notes, it points me to the C:\Users\xyz\Documents\houdini18.5\packages\vray_f or_houdini.json
So I tried to modify this one as well - without luck.

If you agree, could I take a look?

We could arrange a TeamViewer session to be sure what is going on.
You could confirm that except this V-Ray is working fine. Correct me If I'm wrong.
