About Onyx2Max Plugin
Onyx2Max is a plugin for 3d Studio Max that imports ONX files to Max. To access ONX
import in Max, under “File” menu select “Import...” and then select "Onyx 3D Flora"
under "Files of type:". Before you do that, you have to install Onyx2Max plugin by
following the instructions in Installation.pdf found in Onyx2Max folder.

What is ONX file?
ONX file is a proprietary Onyx Computing 3D file format we have developed to suit the
needs of our modelers. At this time, the only 3D rendering and animation package that
reads ONX files is 3d Studio Max via Onyx2Max plugin. The advantages of importing
our vegetation to Max as ONX files are immense. Besides carrying 3D geometry and UV
mapping coordinates, ONX file stores color-per-vertex data and material data including
the textures. And, it goes without saying that ONX file is not limited to 64k vertices
and/or faces per sub-material as is the case with 3DS whose 64k limit will result in any
number of split sub-materials for large objects which will make these objects
cumbersome and time consuming to manipulate.
Currently, the only Onyx modeler that supports all the features of ONX file format is
OnyxGRASS. So, when importing grasses to Max, ONX file will deliver render ready 3D
objects. The other Onyx modelers, i.e. OnyxTREE Broadleaf, OnyxTREE Conifer,
OnyxPALM, OnyxBAMBOO, and OnyxFLOWER, do not export textures and material
attributes because the software does not allow you to set these parameters. However,
ONX export in these modelers allows you to take the full advantage of their color-per-
vertex feature because ONX files will carry color-per-vertex data into Max. We plan to
implement full material ONX support in the future releases of all our modelers.
Key features of ONX file
• 3D geometry
• Color-per-vertex data
• UV mapping coordinates
ONX file is suited to store 3D objects which are built out of triangulated polygons. There
