Well I post to this forum to inform you that Roman from
Caligari (Truespace) would add the .3dm format to
the list of formats if there is enough demand.

That would give access to 3 new renderers including a very
low priced Vray ... up to date animation featureas
and above all some nurbs tools that are not included to Mois 3d
like taper and bend etc. and on top of that isocurve editing.
