Sorry for the delay responding to this message - I only just saw it.
Could not load Octane libraries refer to the log file in your poser temp directory for details
This error means the files from the installer were not correctly copied into the corresponding files in your Poser folder. It may also be a PoserPython install issue - and reinstalling Poser SR3.1 can fix that up.
Poser -> Edit -> General Preferences -> Misc tab will show you your Poser temp directory. Pls post the octaneplugin.log file (or email it to me at [email protected]
) and we'll get you up and running.
