1 Install the Exporter
Use the setup.exe to install the plug-in. You should have 3ds max installed. The plug-in is only tested on windows XP and windows 2000 with 3ds max 5.1. If you are installing on windows98, you should add the installdirectory to your path and reboot your computer. If you are having trouble loading the plug-in when starting 3ds max, then try to load the plug-in directly from 3ds max. Open 3ds max, press Customize -> Plug In Manager, right click the table with plug-ins and press Load New Plug-in, find the install directory and choose OSGExp.dle.

2 Tools in the Exporter
With the exporter come some tools: OSGExport Toolbar OSG Helper Objects fIVE Preview (not available in open source version)

2.1 OSG Export Toolbar
Under Utilities (the hammer icon) -> More -> OSG Export Toolbar is a toolbar for fast access to the exporter. The first button will preview full scene, second button will preview selected objects. Third button will save to OSG file format to the default export directory as exported.osg,fourth button will save to the IVE format as exported.ive also in the default export directory; the .ive format is only viewable with fIVE preview also installed with exporter. The fifth button will let you control the export options, these will be save to disk such that when reopening 3ds max and exporting again the same settings will be used.

2.2 OSG Helper Objects
Under Create (the icon with amouse pointer and a star), choose the Helper icon (the fifth icon from the left), and then select OpenSceneGraph in the drop down box. Here you have access to more OSG related stuff. You are able to create Billboards, LODs, Sequences, Switches, Occluder, and Imposters helper objects and add geometry object to these. Sampling one geometry object over a period of time can also make sequences.Further more you are able to add nodemasks to a serie of geometry objects, and change stateset properties such as renderbin on a particular set of geometry objects.

2.3 fIVE Preview
NOT AVAILABLE IN OPEN SOURCE VERSION With the exporter comes a preview function, really useful when changing the parameters directly in the max model and previewing the result right away in OSG. In the fIVE Preview youare able to change motion model, view wireframe, reset view, save in IVE format, start/stop/pause animations and much more. Right click one time in the preview window to find the menu for doing this. fIVE Preview is also installed as separate program, fIVE.exe, which can run independently from 3ds max. By default install a shortcut on the desktop should lead you to it.

3 Introduction to theOptions Dialog
This section will give a small introduction to the options dialog, which controls the exporting.

Above is a picture of the dialog; it is separate into 6 sections: Output Error Reporting Export to Scene Geometry State Material State Texture State These are described in the following sections.

3.1 Output
Controls the outcome of the exporting. Save it to a file or preview it withfIVE Preview. If we are exporting .ive files, we can include imagery directly in the file. When exporting to .osg files, the “Save Textures Images” should be checked; the images will be saved in an “images” directory in the same directory as the exported file is saved. When using the toolbar, there is no need to use these settings, as these are set automatically. When exporting without using thetoolbar, you should select File->Export (selected) in 3ds max. Choose directory to save to, and write name of file. If the name has the ending .ive, it will be save in the IVE format, if the name ends on .osg it will be saved in OSG format.

3.2 Error Reporting
Check this option if you would like error reporting. When for instance exporting a material, which uses a map channel, and there are...
