Hey all,

I keep getting these warnings when I launch Houdini. I've even tried a wipe and fresh install and the errors persist. Any tips?

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 can't be the only one that has experienced this. No one has any feedback on this?

There’s other threads about this. I’ve even posted about these Console messages appearing since v .391 and .416.

I do not have a specific answer to resolving the issue although mine did go away while experimenting with the env file. There are other suggestions too in different threads I came across (do a search) but did not work for me while it did for other users. Unfortunately I have not seen anything official from Houdini/SideFX staff.

One thing I do notice in the warnings you have is there are different backslashes used throughout the paths like I had. Are you on Windows, MAC, or Linux? I am on Windows 10.

This is usually caused by the Houdini install folder appearing in the $HOUDINI_PATH more than once. Remember ‘&’ is short for default HOUDINI_PATH which includes the install (HFS) folder.

Double check your houdini.env to see that you haven't done something like this:


which will insert the houdini root folder twice.
