Octo Posted February 11, 2014 Share Posted February 11, 2014 Hello. I'm learning Houdini and figured I should try to make a small project in the form of a hanging/suspension bridge to see if I could pull it off. It turns out I couldn't. I tried 3 techniques. 1- Only wire solvers. Works as expected, but interacting with other rigid body objects isn't very solid, so it wasn't what I was looking for. 2-Wire solvers for ropes, packed RBD for boards. Seemed promising, but the constraints holding the boards and ropes together doesn't seem to do much. 3- Wire solvers for ropes, fractured RBD for boards. Here, the point numbers for the boards aren't as I expected so I don't know how to link the boards with the ropes properly. Surely not one constraint for each plank? In this file I also tried to make all the boards into a single RBD just to get something working..and it sort of does, but completely flips out. On technique 2 I have a problem creating the pins/links between the boards and the ropes too. Only one side of the bridge gets connected, and I don't know why, since it should be based on distance, not point numbers or anything. If i increase the connectadjacent pieces radius i do get some more connections, but they are not aligned, so point numbers must be involved somehow... I attached all 3 files in the hopes that someone have the time to take a look and maybe give me a few tips on what I'm doing wrong, or even manage to get it working. Any help would be much appreciated. bridge.zip Quote Link to comment Share on other sites More sharing options...
