A new Revit export plugin has been released!
It is compatible with Revit 2014 / 2015 / 2016 / 2017.
You can find them at the link: http://twinmotion.abvent.com/downloads/
In this new version, various bugs have been fixed. A new functionality has been added as well, which allows users to create .log files when error occurs.
In order to use them, please first uninstall the previous release. After that, you can run the .msi installer.
If the release number on the plugin interface in Revit is different than V 2.1.4, you may have to uninstall manually the old version.
Please go to C:\ProgramData\Autodesk\Revit\Addins\2014, 2015 or 2016 (depending on your Revit release) and suppress the Twinmotion .addin. Then you could relaunch the .msi installation.
