I recently updated Houdini to v18.0.391 and now receive this message whenever H is launched. What does this mean and how do I fix it?


PDG Type Registry: Failed to import duplicate module ‘partitioners’ which was previously imported from ‘D:/Program Files/Side Effects Software/Houdini 18.0.391/houdini/pdg/types\partitioners’
PDG Type Registry: Failed to import duplicate module ‘schedulers’ which was previously imported from ‘D:/Program Files/Side Effects Software/Houdini 18.0.391/houdini/pdg/types\schedulers’
PDG Type Registry: Failed to import duplicate module ‘utils’ which was previously imported from ‘D:/Program Files/Side Effects Software/Houdini 18.0.391/houdini/pdg/types\utils’

i got the same message after updating right now.

Just updated to 18.0.416 and these annoying messages still come up. I checked the houdini.env file it seems okay. I also found some other suggestions to the same error in other threads but they did not work or apply.

I was experimenting with the env file after adding a trial of Arnold and purchasing RenderMan and of course having to add the plugin info to env. loads of trouble started to occur. Seeking guidance on the internet I found one suggestion of having only one “&” at the end of the last “HOUDINI_PATH” variable. That fixed all the Console messages and the PDG errors went away! The plugins are all still accessible with one caveat (RenderMan and Arnold coexisting) but that's for another thread.

Thanks to a video on the youtube [www.youtube.com] I was able to get the houdini.env working as I think it should. All plugins show up and none of those Console errors.
