well thats no problem..maxon made a programm called Magiclink who can convert Calagary,Dfx,fastray,Imagine &silver, lightwave, maxon cinema,pagerenderrer, real3d,reflections, sculpt and videoscape.
we convert the 3d objects in Imagine format and then we convert those imagine objects with 3dto3d into raw objects.
So its really not important:)
