dfmn Posted February 18, 2016 Share Posted February 18, 2016 (edited) Hey guys/gals! Been trying to find a good tutorial or tips on how to use soft bodies in houdini but with no real success. What I wanna do is quite simple but not sure where to start. I wanna copy a bunch of sphere and they just fall and bounce around. Basically this So if anyone got any good tips or a tutorial on how to do that I would be very happy! Thanks!

Juraj Posted February 19, 2016 Share Posted February 19, 2016 Hi, also check this tutorial.As described in tutorial, you can use also wire solver for soft bodys. It should be faster but you may not get volume preservation (not 100 percent sure). Alse I have seen great example here on forums which uses bullet solver and constraints.

dfmn Posted February 22, 2016 Author Share Posted February 22, 2016 (edited) Im still struggling with this. So what I figured out so far is that you can't just copy a bunch of spheres and then use a tissue object, that will just make the whole thing to one object.Been trying to find a way to do this and I check the files from the post that Juraj posted and they're all good but none what I saw used FEM. This is what I got and its clearly not working https://dl.dropboxusercontent.com/u/10345256/copy_fem_test.hiplc Not sure if this is hard to do or if its just me. Any help is appreciated Thanks!

UgStHo Posted February 27, 2016 Share Posted February 27, 2016 I don´t know if there is anything like a fracture object for FEM but you can add them via a sop solver over time maybe ? I did not try that yet its just a idea! Quote Link to comment Share on other sites More sharing options...
UgStHo Posted February 27, 2016 Share Posted February 27, 2016 Okay tried that haha not really working but maybe the grain solver is an option ! It does pretty good volume preservation and is fairly easy to setup ! Also with multiple objects ! Quote Link to comment Share on other sites More sharing options...
anim Posted February 27, 2016 Share Posted February 27, 2016 for something as simple as spheres you don't really have to use embedding copy tetrahedralized sphere, then sim with FEM and extract tetrasurface after sim copy_fem_test_fix.hiplc Quote Link to comment Share on other sites More sharing options...
UgStHo Posted February 29, 2016 Share Posted February 29, 2016 I also found out if you use a dopimport it won't take the donuts as one object if you tick of the single object box. http://www.sidefx.com/index.php?option=com_content&task=view&id=2664&Itemid=132 If you download the Project Files there is a StackOnRotatingFloor.hip in the zip! Which looks like the stuff you want Quote Link to comment Share on other sites More sharing options...
