They may have Goz but they still have to use Lightwave so we win
Is this as 'useful' as Send to max/mudbox?
Don't know, I think is some approach: GoZ aromatically transfer data (geo, texture, correct displacement and normal) from Zbrush to other software, also, you can adjust topology on you application and update with a click geo in zbrush. Very fast and work correctly in modo.
afaik, GoZ for 3d Studio Max is also product of community, which probably means there is no member of zBrush team, experienced with Max, too.
I remember Pixologic publicized GoZ for max before release 4 like preview, so I think no, it is not a community work but was development by Pixologic itself.
If there is any relation, that would be Mudbox, hardly AD will help to competitors, as they already have app in same class. Imagine AD support for AVID Softimage crosswalk... I can't.
