In case you missed the announcement on our 3ds Max forum, we have a brand new 3ds Max exporter in development: IndigoMax!
Through a partnership with Jakub Jeziorski, a fully native plugin for 3ds Max using the Indigo SDK is being developed to take integration with Indigo to the next level. Early releases are available from our forum here: http://www.indigorenderer.com/forum/viewtopic.php?f=9&t=11368
Welcome on board, Jakub!
A simple and fun render with the new exporter has been made by ENSLAVER (click to enlarge):
