really hgih poly zbrush to SI

[Mirko Jankovic]

Anyone have good idea how to get really high poly obj from zbrush, like
10.000.000 polys to Softimage? Exporting to obj get zbrush crashed on 32gb
ram comp.
Decimating or any other stuff in zbrush gives all kind of weird polygons
once imported to SI.
Or at least good point how to get proper normal maps.. we are close getting
them but always something gets messed up. Any point to guide or something
or tips would be great. Thanks
