A quick update.....
The Octane 2.0 version of the plugin is virtually complete - with only a couple of issues to resolve.
The Octane 1.5 version of the plugin appears at this stage to be quite robust (awaiting Modo801 SP1 to resolve the "Scene Close" crash).
Unless people think strongly otherwise, I believe the 1.5 version of the plugin is ready to come out of beta (date to be determined). If you think there are functions missing or bugs that have not been addressed, pls let me know. As per the msg at the top of this thread, there are still a lot of features to add to the plugin - but this can be done on the full (non-beta) version.
And a question for people....for Viewport navigation, you will click a button and then drag the mouse in the Octane Viewport to move the Octane camera (using controls similar to the Modo Preview window navigation controls). Do you want
a) The Modo camera continually tracks the Octane camera in this mode, or
b) The Modo camera does not track the Octane camera in this mode, or
c) The Modo camera does not track the Octane camera in this mode, but when you exit Viewport Navigation the Modo camera is set to the final position of the Octane camera.
I am unsure if Viewport Navigation will be able to be implemented no OS X.
