johnLIC Posted November 19, 2014 Share Posted November 19, 2014 I am trying to emit rigid bodies, like dirt from behind a truck tire. I am trying to reproduce this: http://valeriodinapoli.blogspot.com/2013/02/houdini-how-to-create-rigid-body-emitter.html I have my scene looking as close to his as I can, but I just get particles that don't seem to be getting any dynamics - they just hang out at their birth positions. I also have errors downstream of my RBD Point Object node. When I dive into that node it looks different from the one I DL'ed off the link above. I made all these nodes by hand. I did not use the "RBD Point Object" shelf button. I suspect that I left out something which that button does. I have attached my file. Any help appreciated. jp_RBD_emitter_v01.hiplc Quote Link to comment Share on other sites More sharing options...

Since H13 the prefered way of emitting RBDs is by using packed primitives and a sop-solver as emitter. Merge in the primitives you want to become rbs. There are a wide range of files doing this in this forums, but since its wednesday I´ll give you one more. rbdEmitter.hiplc 1 Quote Link to comment Share on other sites More sharing options...
johnLIC Posted November 20, 2014 Author Share Posted November 20, 2014 Thanks! I need to read up about packed primitives. I just opened your file and it works great. I will have a very close look... Quote Link to comment Share on other sites More sharing options...
johnLIC Posted November 21, 2014 Author Share Posted November 21, 2014 Hi, I am rebuilding a copy of your file as a way to learn about it. Is there an easier way than building the whole thing by hand? Like a shelf button that sets up the sop solver in the autodop network? I ask not out of laziness, but because I want to know the most effiecient / normal way to do things. Thanks! Quote Link to comment Share on other sites More sharing options...
johnLIC Posted November 22, 2014 Author Share Posted November 22, 2014 I created the nodes in the emitter network, down to the "rest" node, and then I hit the "RBD Object" shelf button. That seems to have given me something much closer to what you have in your scene. Quote Link to comment Share on other sites More sharing options...
