EdwardBrian Posted February 22, 2011 Share Posted February 22, 2011 (edited) I'm trying to drive the extrusion of a bunch of polygons and what i've got so far is working but it's too lineair to my liking. The way i've done it so far is with an expression, i added an attribute to the primitives (polygons) with a AttribCreate SOP and put an expression on it: min(1,max(0,($T-(1.5*rand($PR)))))* (1.3 + 0.1*rand($PR)) This attribute is used in a polyExtrude Sop. This way the extrusion grows over time and is random over time and extrusionlength but the movement is just simply lineair. In the chops tutorial on the SideFX forum the tutor says to allways try to input points to chops, not primitives. But then how could i use chops to drive the extrusion of my polygons? Hopefully someone could shed some light on this for me as i'm fairly inexperienced with chops. Tnx in advance. __________________________________________________ ugg boots uggs Edited February 24, 2011 by EdwardBrian Quote Link to comment Share on other sites More sharing options...
Macha Posted February 22, 2011 Share Posted February 22, 2011 (edited) Edward, if you promote attributes afterwards and don't mind about the resulting averaging, here is one thing you can do. chopstrude.hip Edited February 22, 2011 by Macha Quote Link to comment Share on other sites More sharing options...
