Scanner Posted June 28, 2003 Share Posted June 28, 2003 ...using the Spring SOP (Thanks, Sirogi! ) to make pigtails that bounce on a hyperactive model. BUT The occasional pigtail is sliding through the model's face (disappearing at the nose, reappearing at the chin) for a truly frightening effect. I can't delete individual 'problem' strands because too many of them fail once (though they bounce properly 90% of the time). any ideas?

Scanner Posted June 29, 2003 Author Share Posted June 29, 2003 approximate the model's geometry with metaballs; pipe it through a Force SOP (with radial force at a minus value); and into the Spring SOP. Quote Link to comment Share on other sites More sharing options...
old school Posted July 1, 2003 Share Posted July 1, 2003 Try increasing the Time Increment (Time Inc) parameter from 1/$FPS to 0.1/$FPS. This parameter determines how may times the spring SOP evaluates per frame. 1/$FPS evaluates on frames where 0.1/$FPS evaluates 10 times a frame.

stu Posted July 17, 2003 Share Posted July 17, 2003 Is the collision geometry triangles? Houdini doesn't like to perform collisions on quads or others because of the possibility that some polys might be non-planar. So, if your collision geomentry isn't triangulated, you might try triangulating it with a divide SOP. stu Quote Link to comment Share on other sites More sharing options...
