Hi guys! I tried to install Renderman but found this problem when I setup the .env:

RMANTREE=C:\Program Files\Pixar\RenderManProServer-24.1
RFHTREE=C:\Program Files\Pixar\RenderManForHoudini-24.1
RMAN_PROCEDURALPATH=$RFHTREE\18.5.596\openvdb;&
HOUDINI_PATH=$RFHTREE\18.5.596;&
PATH=$RMANTREE\bin;&

houdini console send me this:

ModuleNotFoundError: No module named 'menutools'

Error running Python dynamic menu strip script:
Traceback (most recent call last):
  File "<stdin>", line 3, in expression
ModuleNotFoundError: No module named 'menutools'

Error running Python code:
Traceback (most recent call last):
  File "C:/Program Files/Pixar/RenderManForHoudini-24.1/18.5.596/scripts/456.py", line 1, in <module>
    import menutools
ModuleNotFoundError: No module named 'menutools'

actually I have working with Python 3... could be this the problem?
if it's the problem... there are some way to open or change houdini with python 2.7?

Thanks in advance!

The renderman installer can install the py3 or the py2 version. If you installed the wrong one you can run the installer again and only install the bridge for houdini again.

When you install Renderman 24.1 for Houdini, the py3 version is hidden by default, while the py2 version is selected. So anyone who has the same issue be mindful of:

When installing with the Renderman Installer, after logging in, select "Show all", and click on Renderman 24.1 for Houdini (python 3)

In the ENV file, dont forget to change the name of the folder that just got installed in the Pixar folder:

RMANTREE=C:\Program Files\Pixar\RenderManProServer-24.1

RFHTREE=C:\Program Files\Pixar\RenderManForHoudini-24.1-py3

RMAN_PROCEDURALPATH=$RFHTREE\18.5.596\openvdb;&

HOUDINI_PATH=$RFHTREE\18.5.596;&

PATH=$RMANTREE\bin;&

(Renderman website gives by default this folder for the path: RenderManForHoudini-24.1)

Patar, finally you solve it? with the answer of Mefistofeles i already solve it! im my opinion for the Renderman wizard there are 2 problems to solve to make this instalation friendly.

Automatic install the version with the Python that you need and auto write the .env file. In any case, if they can't do it (I think they could) they could make a small guide during the instalation asking for what houdini are you using...

Does this work only for Renderman Commercial? Does Renderman non commercial work with python 3?
I currently have Python 2.7.15 on Indie.

This works with Renderman non commercial. I would reccomend you to start installing Python 3 versions since Houdini (and everything) seems to be shifting towards it. After some of the 18.5 builds its shown how they are working with Python 3. However I am not an expert on these details, but these forums have plenty of very knowledgeable people that can explain it to you with every detail and much better than I can.

Just for anyone who will encounter similar issues. Installation via .json file and Houdini packages folder.

Installation through adding an environment variable to houdini.env caused conflicts for a weird reason.

And that has nothing to do with adding -py3.

1. Make sure RenderMan for Houdini is Python 3 version.
2. Use installation via packages (json file). RenderMan has provided a json file at: "C:\Program Files\Pixar\RenderManForHoudini-25.2\packages\renderman_for_houdini.json"
3. Copy-paste this file to: "C:\Users\<YOUR_USERNAME>\Documents\houdini19.5\packages" (houdini<your_version_of_houdini>).
4. Delete everything related to Renderman from houdini.env (if written before) as json file will do the same and if both are used together, it may cause conflicts. Related post: https://www.sidefx.com/forum/topic/71405/?page=1#post-302661 [www.sidefx.com]

Find "Package installation": https://rmanwiki.pixar.com/display/RFH25/Installation+of+RenderMan+for+Houdini [rmanwiki.pixar.com]

For Houdini 19.0 and beyond, RenderMan for Houdini can be installed with a packages file, found in the RfH installation directory.
