  1. Hey guys, Im playing with the Wire solver and I managed to get a series of wires from one plane to another to dangle (mostly using the shelf tools). What I would like to do is to start with just a couple of wires and over time increase the number. As you can see in my scene file the number of wires is determined by the scatter nodes... but if I animate the points count there the simulation breaks. Any idea ? thanks! mj_wires.hip
  2. Hello all, I'm using Houdini's Wire Solver for my master's thesis on hair simulation. In the text I want to talk about the way hair is being simulated. Based on the parameters the Wire Solver offers, I expect it to simulate Wire Objects like a mass-spring system. When searching the documentation, I can't seem to be able to confirm this. Does anybody here have some confirmation of it using a mass-spring system or have a different intuition about how the Wire Solver works? Thanks for any reactions, Tim
  3. Hi there, I'm trying to connect a wire object to a sail. So far so good. Unfortunately the wire is stretching and stretching. Redusing density or mass isn't helping, also the linear spring constraint isn't doing anything usefull. Actually a pretty high value lets the wire behave crazy. What would be the way to prevent that dudes from stretching?
  4. Hey there, I am currently trying to simulate a (single) falling fir-branch like the ones you can see in this image: I would like to use a wire solver for that, but I am having a hard time to make the needles stick to the branch. How would you go about that? Desired setup: * branch as wire obejct (soft body behavior when colliding) * needles as wire object attached to the branch (soft body behaviour as well) * gravity in place, falling fir-branch, colliding with a ground plane. I tried the "Attach wires to surface" shelftool, but that attaches the selected wire points only to existing points on the branch-geo (which is low res, with just a few points). I would like the needles to be independent of the branch geo so that I can have a rather lowres branch geo (tube, less subdivs), and lots of needles. I would like to attach them like it is possible with folicles in maya, having them stick wherever they are on the surface, not having them stick to one of the input points on the fir branche geo. Using the point attribute "pintoanimation" or "gluetoanimation" also does not work. Doing so, the needles jitter around as soon as they are not in line with a points of the underlying branch geo. Do you guys know any solution for that? Thanks in advance for your time and help! Cheers, Philipp
  5. Coming from 3DSMAX I'm looking for a way to have a 'hose' connected to and move freely between two animated objects. As a test I have two boxes, between which I have drawn a curve/line. The two boxes I then convert to static rigid bodies, and the curve into a wire. If I use attach wire to surface - the wire then drifts away from the point I attached it to. I've tried changing the strength but it doesn't have any impact other than exploding at higher levels. Could someone point me in the right direction please, as it would be greatly appreciated. I'll have to apologise, I discovered that if I change the constraint type value from soft to hard I appear to get a similar effect, although it doesn't like dynamically stretching?
  6. Hey all, I am very new to Houdini and am trying to use the wire object/wire solver to simulate fur on a tiger. I have it setup and working, but when I increase the number of curves I'm simulating, I get some issues. Mainly, some of the wires get caught inside the tiger geometry and look like they get stuck and therefore stretch. It seems to be when the tiger's legs come very close together, the wires from one leg get stuck inside the other. Does anyone have any experience on how to resolve this? I am using volume based collisions on a static object and static solver, and the settings are pretty much the default settings. Any help would be greatly appreciated. Thanks.
  7. Hi everyone! I'm trying make this effect http://youtu.be/YAHExJE53gs?t=23s but there is an artifact like thishttps://www.dropbox.com/s/l2atvfs6aucij1u/wire_problem_elastic.jpg i tried most attributes,but I can not define a parameter if there is a knowledgeable person, tell me an advice please test_wire.hip
