Hayden Posted March 25, 2017 Share Posted March 25, 2017 I have two separate stacks of geo made using copySOP's, i am trying to get them to interact with each other. They do interact with each other but the constrains only effect one model, i can switch them in the merge but its only ever one that holds together, the other falls apart instantly no matter what the glue strength is. Ive put photos below and attached the scene file with the model that needs referencing in. New to Houdini so any help or advise would be greatly appreciated! Thanks PlateSimulationTest001.hipnc plate.obj Quote Link to comment Share on other sites More sharing options...
Atom Posted March 25, 2017 Share Posted March 25, 2017 (edited) Hmm..I don't really dig the Copy before fracture. This means all plates in one stack will always have the same fracture pattern. But moving on. What you can do is simply animate the glue strength. Keep the strength high until the plates are in free fall then animate it to a lower value over one frame. This way when they hit the floor/ground the glue bonds will break on impact. When ever you animate a value that has one of those Default dropdowns next to it you must remember to change it's setting to Set Always. This way the value will be considered on every frame change and not just at the start of the simulation. ap_PlateSimulationTest001.hipnc Edited March 25, 2017 by Atom 2 Quote Link to comment Share on other sites More sharing options...
