supertom44 Posted February 18, 2012 Share Posted February 18, 2012 Hi all, first of I apologise as I am new to houdini so you will have to bare with me a little. I have fractured a box using the Voronoi fracture sop as you can see in the attached image. I am looking for a method where I can control which pieces fall away under gravity and which stay where they are, id like to be able to animate it as well. My first thought was to use gravity and try and limit which pieces it affects and animate it over time, so the pieces in the center or at one of the edges start to fall first then it progresses to the other pieces. I tried creating a group at geometry level and using that in the gravity field but I couldnt get it to work. My second thought was to use a Glue object and animate the glue strength for the individual pieces, but not sure if thats possible or if thats the right way to go about it. I was wondering whats the best way to go about creating such an effect? Cheers. Quote Link to comment Share on other sites More sharing options...
anim Posted February 18, 2012 Share Posted February 18, 2012 you can for example animate active value of fractured object by any attribute on fracture source points as in this example DOP_active_value.hip Quote Link to comment Share on other sites More sharing options...
supertom44 Posted February 18, 2012 Author Share Posted February 18, 2012 Many thanks for the reply that is exactly what I was looking for. I used a slightly different method which used groups to set the value as I'm new to VOPS. Thanks again. Quote Link to comment Share on other sites More sharing options...
