Vray works but Console gives Errors on startup and Houdini help does not show up after installing - Houdini 18.0.391

V-Ray for Houdini V-Ray for Houdini :: Issues
1

Hi,

I installed vray by modifying the houdini.env file like that:

Vray works without problems but its printing some erros to the console on startup.

I also noticed that the help inside Houdini will not work if I have installed vray. If I remove the vray installation from the .env file the help works again.

I would appreciate some help about that.

kind regards
Jon

Sorry…didn´t checked the forum that much and postet that a little to quick.

I got some help from this thread.

What I did now:

PYTHONPATH=“${VRAY_APPSDK}/python27;${PYTHONPATH}”

…to the end of the env file. That removed the VFH Errors.

I changed the PATH entry to :

PATH=“${VFH_PATH};${PATH}”
vs
PATH=“${PATH};${VFH_PATH}”

that made the help come up again.

Still getting this errors:

VFH * Build number:6698 hash:f2f25ad from 24 Mar 2020 04:59
PDG Type Registry: Failed to import duplicate module ‘houdini’ which was previously imported from ‘C:/PROGRA~1/SIDEEF~1/HOUDIN~1.391/houdini/pdg/types\houdini’

I’ve messaged SideFX about this already - those errors only show up if ${PYTHONPATH} is appended back to itself, as in your post. If you append it multiple times, you’ll get those errors printed multiple times.
The PDG errors are benign - they won’t cause you any trouble.
I’m hoping it’ll be resolved soon. Not much we can do on our end - I’ve got SideFX labs and Deadline throwing the same errors here when V-Ray is not present anywhere in the environment variables setup.

Hope that helps!

change

HOUDINI_PATH=“${VFH_HOME};${HOUDINI_PATH};&”
to
HOUDINI_PATH=“${VFH_HOME};&”

Okay now I dont have any errors and the help File shows up. Nice.

Do I have to be aware of anything else is/behaves different now ? :slight_smile: Since Im not totaly sure “what” I did or why the help shows up if I invert a line in the env file.

Thank you both.

I changed red to green.
