Lud83 Posted June 16, 2014 Share Posted June 16, 2014 Hi everyone, I am having some hard time understanding the sopsolver especially when it comes to colliding two rbd objects. I already read through a couple of forum post and looked at the respective example files - even the included Houdini one (Torus and Particles) However, when trying to change the collision object to a simple RBD object the whole system stops working. I have no idea why and I am desperate to try to understand whats going wrong. I tried dozends of variations, I checked the detail view to see if impact data are recorded, but nothing worked. I'll upload a test object which is basically the demo from Sidefx but with some alteratoin to try it out how to use rbd impacts. Hopefully someone can explain to me how to do this. Cheers and thanks Lud SopSolver_Issue.hipnc Quote Link to comment Share on other sites More sharing options...

wateryfield Posted June 16, 2014 Share Posted June 16, 2014 Your DOP Network doesn't create the Feedback parameter. The copy_per_impact node need it. I think you need particle collision. Or try to use Impact replace. Quote Link to comment Share on other sites More sharing options...
