Here is version 1022-03 It has been recoded to avoid an annoying glitch that was just reported on some MACs where there was an extra blank button on the Octane Render Toolbar when it was displayed horizontally ... This new version has been tested and it should now work cross-platform with a correctly made one-button toolbar in all configurations.
As we seem to have resolved all of the outstanding issues with the tool [ ] there only remains future updates to suit any new versions of Octane Render that come out - hopefully there will be one very shortly !
