Yes Pilou,

I used t-spline for rhino,

So in rhino you import the obj as an sds cage with the tspline plugin (not with the rhino obj import of course), t-spline create a t-spline version of the cage ... then convert it in nurbs, and save it in .3dm.

There was also an tool in the t-spline toolbox you have to use to smooth the blending between every patches. (I don't remember the name)


Now again, until one hour ago, I was thinking that the sds->nurbs was only possible with this t-spline plugin ... but if maya can do it natively, we maybe don't need an alien technology to get the same thing in MoI ... crossing fingers :o)
