isah_voodoo Posted November 12, 2018 Share Posted November 12, 2018 Hello, I am scattering points over a certain number of frames in Sops . I want to be able to record the Frame in an attribute when the point is born. I know I can use the @Frame attribute but that will constantly record the frame number..I need the attribute to freeze only on the frame it is born for each point. There used to be a thread on this but i can't seem to find it.. Any help would be amazing, I will attach my file if anyone wants to see. Thank you. recording_start_Frame.hipnc Quote Link to comment Share on other sites More sharing options...
3dome Posted November 13, 2018 Share Posted November 13, 2018 (edited) you need a solver SOP for that and a condition like if(not pointHasExistedOnPreviousFrame) i@birthFrame = @Frame; Edited November 13, 2018 by 3dome Quote Link to comment Share on other sites More sharing options...

TheDude Posted November 13, 2018 Share Posted November 13, 2018 scatter the new points per frame and set @BirthTime to -1, in a solver, merge these new points with the previous frame, if @BirthTime is not -1, set @BirthTime to @Frame Quote Link to comment Share on other sites More sharing options...
