patis 3 Posted February 23 Hello, I want to delete alembic cubes when collide box. But using solver to write attributes, The alembic couldn't move.. (I know the reason that is read looping for the first frame..) Anything way to avoid this? Thank you ToOdforce.7z Share this post Link to post Share on other sites
dleonhardt 19 Posted February 23 The reason the cubes won't move inside the solver is because the 'Prev_Frame' Dop Import doesn't reference the actual previous frame, like a timeshift with $F-1 would do, it references the output(!) of the solver from the previous frame. Which means that you have to output 'Input_1' and copy the attributes from 'Prev_Frame' in your case. movingobject_dl.hipnc Share this post Link to post Share on other sites
