Very cool software. I am very happy with OnyxGARDEN SuperBundle. Fast render times and stable workflow with Vray + Max.
The new OnyxGARDEN SuperBundle version 2.1 for 3ds Max. The package contains the latest TREE STORM plugin for Max and six stand-alone plant creators/generators/editors with corresponding libraries of more than 460 ready to use trees, shrubs, palms, bamboos, flowers, grasses, and grass covers! Furthermore, the SuperBundle includes our Onyx2Max import plugin for bringing Onyx plants to Max.

Is this compatible with 3DS max Design 2013?
Hello Chad, sorry for the delay in answering your post. The onyx software is not compatible with 3ds max 2013 yet.
You can try with Forest Pack Pro, they have a beta versions for Max 2013. http://www.itoosoft.com/downloads.php
Ok, Thanks! By the way, my company purchased the Onyx software and the only thing that is not compatible right now is the Onyx2Max plugin. FYI.
