Hi,
Please find updated material libraries for Octane version 2 attached to the bottom of this post.
To install them, copy and overwrite the existing libraries in your Forest Pack installation directory. By Default this is found at C:\Program Files (x86)\Itoo Software\Forest Pack Pro\matlib.
These files will be included by default in the next version of Forest Pack, libraries to support older versions will be available as an optional download.
Many thanks!
Paul
