In this week i released the plugins new version.
The most important thing is the exporter format is changed. I implement a new feature (Separate by elements), that was why I needed it.
So you need update the importer plugin if you use the exporter. The full change-log is available here. They contains lot of bugfixes, and many improvements, so i recommend to use it.
And one more thing. In Cinema 4D R21 the plugin licensing was changed, because C4D licensing was changed.
