Hello everyone,

i've installed Renderman 22.5 for Houdini 17.5 and set up the houdini.env file as written in the Renderman Documentation. If I start Houdini, I always get this message in the console:

Unable to find libprman. Resorting to backup string table. Rendering will error
Error running pythonrc.py:
Traceback (most recent call last):
File “C: /Program Files/Pixar/RenderManForHoudini-22.5/17.5/python2.7libs/pythonrc.py”, line 41, in <module>

from txmanager.txparams import TXMAKE_PRESETS
ImportError: No module named txmanager.txparams

The Renderman-Part in my environment file looks like this:

RMANTREE=“C:\Program Files\Pixar\RenderManForHoudini-22.5”
RFHTREE=“C:\Program Files\Pixar\RenderManForHoudini-22.5”
HOUDINI_PATH=$HOUDINI_PATH;$APPDATA\SideFX\GameDevToolset\17.5\1.159;$RFHTREE\17.5;&

Do you guys have an idea, how to fix this issue?

Best Regards,
Chrizzo

Hi
your entry for RMANTREE looks wrong to me, it should point to ProServer like this:
RMANTREE=“CProgram Files/Pixar/RenderManProServer-22.5”
best regards

(eh- without the emoticon, this is a bug from the website)

Thank you very much

Hello, I have still issues on houdini 17.5.258
I have correct env files, but I can't eg. create light some python errors… anyone succeded?

I think the best place to get support for the plugin is on Pixar's RenderMan forum. I have it working fine making lights and shaders and all that on macOS but there are some stability issues with IPR in the release version.

Make sure that the Houdini path variable has RenderMan lines first in the list if you have multiple entries.

I had the same issue and put the RenderMan line first ( before Redshift and Octane lines which I have installed as well )

That fixed the issue.

Solved. I had different problem. I had custom HOUDINI_OTLSCAN_PATH and that was the problem. Renderman keeps his asstes in different location
