derm Posted June 3, 2011 Share Posted June 3, 2011 Hello! I'm not really a new Houdini user but I'm still not well-versed in it either. I was wondering if something like this is possible...rather, I'm sure it is I just don't know how I would go about doing it. I want to have a wall (just elongated box...really simple) standing up. I want to then throw something through it. Think like a rock through glass. Let's say I have the rock go through the very center. Well, my question is: how would I go about making the bigger chunks stick where they are and only have the smaller chunks fly away? I currently was just using the "make breakable" button on the wall. I was really trying to avoid painting in fractures and going in and manually picking what pieces I wanted to have stick. Thanks for the help!

lukeiamyourfather Posted June 3, 2011 Share Posted June 3, 2011 Constrain the object to the ground and exclude the ground from the objects that can initiate a fracture. Instead of "*" it would be "* ^ground" or whatever the ground happens to be called in your scene. Quote Link to comment Share on other sites More sharing options...

But I constrained my wall and threw a sphere at it and it didn't exactly work. I mean, I understand what's going on. When the fracture happens, new pieces are being created with a new name. The constraint says, "Oh hey, you're not 'box1', you're free!" There's gotta be a way to get around this I'm just not sure yet how. Maybe I'm approaching it the wrong way? But I attached a little test scene. Maybe someone a little wiser than I knows how to do what I'm going for? Thanks! Quote Link to comment Share on other sites More sharing options...

derm Posted June 6, 2011 Author Share Posted June 6, 2011 Ah found a similar problem AND a solution. Just for future reference if any one needs. The last post (minus mine) is exactly what I was looking for. Quote Link to comment Share on other sites More sharing options...
