jordibares Posted March 1, 2017 Share Posted March 1, 2017 (edited) I am struggling to architect what I have in mind and it may be quite simple but... somehow I just don't get how to connect the dots. Attached is a file with a fractured sphere (thin shell) and a small obstacle inside moving fast, I want to break/weaken the glue constraint based on the impact data (may be after a certain force of impact. At the moment the sphere gets moved around by the obstacle, instead the sphere should break on contact with the bullet, but not against the floor. Thanks in advance. PS. All the elements inside the attached scene are using the shelf tools, specially confusing is the ImpactAnalysis. impact_glue_interaction.hip Edited March 1, 2017 by jordibares Quote Link to comment Share on other sites More sharing options...
vtrvtr Posted March 1, 2017 Share Posted March 1, 2017 You don't really need the impact analysis Check the hip impact_glue_interaction.hip Quote Link to comment Share on other sites More sharing options...
georgeivan Posted March 1, 2017 Share Posted March 1, 2017 Also you could use packed primitives.This course its really good http://www.cgsociety.org/training/course/destruction-in-houdini Quote Link to comment Share on other sites More sharing options...
jordibares Posted March 2, 2017 Author Share Posted March 2, 2017 Thanks vtrvtr and georgeivan... seems obvious now although it is hard to structure it at first... I guess I can query the object that caused the impact and decide if I want break or weaken the glue constraint... So much to learn... thanks once again.
