ehsan parizi Posted July 5, 2011 Share Posted July 5, 2011 Hi all, I have a huge tall grid that some objects are copied to its points, and a bounding box that kills those objects that move outside the frame. As you know $PT is not unique, and when a point is killed its number is assigned to a new point, and it's causing a motion blur problem for me! the motion blur goes crazy when a point is deleted and $PTs change, so I wanted to know if there's a way to make houdini to generate unique point numbers? something that works with motion blur too?!

bhaveshpandey Posted July 5, 2011 Share Posted July 5, 2011 before the point/particle is killed copy the point number attribute to some other attrib like oldPt or something (particles usually have id attrib already assigned for this purpose). Since you are deleting after assigning the point numbers, they will stay unchanged. hope this helps. cheers. Quote Link to comment Share on other sites More sharing options...
