papsphilip Posted November 16, 2021 Share Posted November 16, 2021 i have an initial selection of primitives that i append to over time. How can i track the birth and age of the newly added primitives in the group? i m stuck in the birth-age problem, but i have managed to isolate the newly added prims to the existing group. add_to_group_and_track_age.hip Quote Link to comment Share on other sites More sharing options...

Hi, look at the attached file add_to_group_and_track_age_01.hipnc Quote Link to comment Share on other sites More sharing options...
papsphilip Posted November 16, 2021 Author Share Posted November 16, 2021 (edited) it works like a charm thank you!! The birth attribute is not quite right for some reason. i was expecting an integer for each prim that doesn't change over time Also how can i extrude or transform those newly created pieces, while deleting their previous non deformed/transformed state? is it doable in the same solver?because i ve been at it for some hours with no luck although it seems straightforward (sorry the second file is my hacky way) add_to_group_and_track_age.hip add_to_group_and_track_age.hip Edited November 16, 2021 by papsphilip Quote Link to comment Share on other sites More sharing options...
