Instead of using ARive’s in-built converter based directly on osgCONV, the best way to get your models to display correctly with materials/lights/animation etc. is by using a plug-in for MAX called osgExp:

Simply create your model in 1:1, units set to metric: mm, and export it directly to .ive.
Load it in ARive’s library, and you’re good to go!
