Yoj can.use either or, but one will be more optimal. you can use the performance monitor to see the millisecond effect of each node _________________ -G Back to top zarti Houdini Expert Joined: 12 Jul 2007 Posts: 302 Location: inside Posted: Mon Dec 26, 2011 12:42 pm GMT    Post subject: Re: Does knife SOP and clip SOP the same node ?

For what reasons dose houdini have such design ? hi , the main difference seems to be this point 3 sentence in the Help system about the KnifeSOP : Code: Drag a line to specify the plane along which to divide/clip. .. indeed , i just tried . =) the ClipSOP doesnt let you draw a cutting plane in viewport ; like KnifeSOP does . everything else looks identical .. _________________ except the things that cannot be seen , nothing is like it seems .
