  1. Hi! I'm trying to build a simple constraint network with two sets of wires (pink and black). Each set of lines should be connected within itself, and should be repelled to the other set. The wires simulate ok and the constraint of WireGlue works to keep them together. The problem is when integrating the WirePush (Bullet soft constraint, restlength 1.5), it all gets connected weirdly. I have tried it with Spring constraint and it's the same, it doesn't push the wires at all just gets jumbled. I can't seem to figure out what's wrong as I have followed examples of merging multiple constraints by creating and assigning @constraint_name. Any help would be super appreciated! network_constraints_question.hipnc
  2. Problem with Vellum and Rest Length

    I need help solving this issue! it is driving me crazy… When I increase the Rest Length attribute of a pressure constraint (using vellumconstraintproperty and restlengthscale parameter). The object moves erratically, unstable… I have tried with different resolution geometry, sim scale, substeps, constraint iterations, smoothly animating the attribute, etc.. Do not know how else to troubleshoot. Thank you in advanced, Alan vellum_problem.hiplc
  3. Is it possible to change the restlength constraint in only one direction in a Vellum setup? It would be great for something like a rubber band that we want to tighten around an object without making it "thinner"
