First of all , THANK'S FOR YOUR TIME TO DO THIS.
I don't know if is my fault or not:
my spec; Win 7 64 Bit, Softimage 2011, Zbrus4r3
I,ve installed everythingh, i export from Zbrush to Softimage work fine, when i add a couple of mesh in Softimage(for example 2 sphere like eyes) onto the previous model, and re-send in Zbrush, i've in z brush 2 or 3 ztl different model: one is the first i've send and a couple or more for each mesh i build in Softimage .
Is it normal?
