Can’t open .stl created in zbrush in cinema 4d. Get massage unknown file format.
.stl created in C4D reopened normally.
At the bottom of the 3D Print Hub plugin (or 3D print Exporter if you’ve not updated) there are the Export Options. STL can be exported as Magics or SolidView, and Binary or ASCII. Try changing the options to see if it makes any difference.
Correct, changing Binary to ASCII do the job.
Thank You Markus !
