Illumination is there but if you can extend it surely more knowledge is always better.
HardFFlip wrotev4 export plugin
Well the definition is there and can be used to make an exporter for someone familiar with the plugin architecture of 3dsmax (I would probably expect a blender plugin instead but who knows) I myself really doubt to be able to find the time to learn this (since not every aspect of the scx file format can be edited in 3dsmax, thinking about the flags of a material in particular, the plugin needs to define some custom modifier and/or material to properly set every property of the resulting scx)
Nevertheless I maintain that, although archaic, using 3dsmax5 and the original exporters are preventing a lot of issues exactly because of the limitations it holds the modder to, the avarege quality of mods is low enough with "only" needing to care to make the cfg, rpk, and java definitions without errors, if one would more easily be able to make bad meshes aswell whether because of a badly written exporter or simply because the limitations were stripped... I dont know, it seems to be a far too complicated system to integrate into already :/
