Well I suppose it's quiet hard to give this kind of compatibility between two software, more over when it's about shading stuff. I mean modo shading tree can be quite complex already and I'm really not sure Rhino can handle stuffs like layers mask by object id for example, something really typical from modo ... or stuffs like vector displacement map.

I'll be really happy if the translator allow to just render Nurbs in modo, like npower translator for max ... that would be huge !
