MoI -> Octane render (little problems)

Hey guys

Remember my Edirol Roland field encoder model ?
http://moi3d.com/forum/index.php?webtag=MOI&msg=2804.1

Well I want to render it in Octane render

All goes well, I export as OBJ in triangles and load the model in Octane

But I see one problem, in MoI I got for example 1 style called "Front panel" with two objects inside "inner panel" + "outer panel"
Problem is that Octane see only one materials called "Front panel" and I can't make two different materials for the inner + outer panel

Is there a way to export in another format that support objects, import in blender, and tell to blender to export 1 material per object ?
Or is there a way (a script) in MoI that make 1 object = 1 style based on the object name ?

I could do all by hand but it would by painfully long :(

I need help :)
