I’ve had these 2 issues in the past but I could never get them resolved:
1. GoZ from Zbrush into Max 2018 would just open a new instance of Max of an empty scene
https://forums.autodesk.com/t5/3ds-max-modeling/goz-opens-new-instance-of-max/td-p/7284116 is the closest thing I’ve found and no one seems to know what to do still. Some suggested it’s an Autodesk issue but regardless, I’ve yet to see any promising comments.
2. The scaling was always off between max and zbrush
I’d have to Unify for everything in ZB to work properly but reimporting into max would make objects really small. The only promising solution was this: https://forums.autodesk.com/t5/3ds-max-animation-and-rigging/3dsmax-zbrush-goz-and-scaling-issues-while-setting-up-for/m-p/5287077#M12712 However, I can’t test it when GoZ can’t successfully export it into Max.
I’ve been stumbling into posts I’ve made half a year ago about these issues and it still doesn’t seem like either of these have a solution unfortunately. Not trying to sound flippant but did max2018 users just silently fix the issue or implicitly agree not to use GoZ? I’ve searched for solutions the entire day without any success.
