Koen Hofmeester Posted June 24, 2009 Share Posted June 24, 2009 Hi All! Im working on a project that involves a lot of small objects to fall down and collide with each other. My geometry consists of a big grid of different shaped boxes. I want to try the new ODE solver for this so I have to figure out a way which does not involve the RBD fractured dop. I was thinking about instancing each "object primitive group" to a grid of points, with a point for each object, and then using an RBD point object with the ODE solver. So my question...is there a way / an expression I dont know, to instance primitve groups to points, bases on a matching ID attribute? So point 1 gets PrimitiveGroup_01 instanced to it? Thanks & Cheers! Koen Quote Link to comment Share on other sites More sharing options...

However, if you split up an object (based on its groups) into lots of separate objects, then yes, that'll work fine. You can then use a CreateAttribute SOP to create an "instance" attribute on each point with the absolute path for each instantiated object.
