Hi Sven, in my projects i had to do lots of cuts of CADs object, and in XSI i used slice PolyMesh in ICE (attach it to null for control), but without automatic cap (it flicker too much) and then create poly from border edge. that workflow alow me to do animated cut out without flickering and artifacts
several moths ago i switched to Houdini, and i'm impressed how it works, just now making one cutout of animated valve with moving parts and it go like a charm, totally recommendation. quick example: http://g.recordit.co/lEs1G1NfQs.gif On Mon, Sep 11, 2017 at 7:03 PM, Sven Constable <sixsi_l...@imagefront.de> wrote: > FYI: seems to me the standard boolean operator in XSI 2015 creates a > memory leak.
