Masoud Posted October 27, 2022 Share Posted October 27, 2022 Hi guys, I would like to connect some points based on their "ptnum", using an attribute called "id". The problem is it doesn't work. How can I fix it? Thanks for helping. Connect Points.hip Quote Link to comment Share on other sites More sharing options...
Atom Posted October 27, 2022 Share Posted October 27, 2022 (edited) That's because all your IDs are unique. Add can only connect a series of points that share the same ID. Try altering your wrangle to this and observe the result. if (@ptnum==0){i@id = 0;} if (@ptnum==1){i@id = 0;} if (@ptnum==2){i@id = 0;} if (@ptnum==3){i@id = 1;} if (@ptnum==4){i@id = 1;} if (@ptnum==5){i@id = 1;} if (@ptnum==6){i@id = 2;} if (@ptnum==7){i@id = 2;} if (@ptnum==8){i@id = 2;} I often use Add following a trail sop out of particle system to create lines from a particle in motion. Trail count becomes line length in that type of setup. Edited October 27, 2022 by Atom Quote Link to comment Share on other sites More sharing options...
