  1. Can you prevent displacement in Houdini from stretching? I've thought of creating a scales material, either directly in Houdini or in Substance Designer and export it in Houdini. I want to generate scales procedurally on reptiles like dinosaurs. I also only want the skin between the scales to stretch when dinosaurs move, not the scales themselves. Tiny scales like the ones on this dinosaur. https://cdna.artstation.com/p/assets/images/images/010/901/196/large/jacob-baardse-pararender.jpg?1526848727
  2. How do I skin connected curves?

    Hi all, I have a more comlex issue to solve but have essentially boiled it down to not being able to skin a curve that splits off like the T junction shown below. How would i be able to skin the curves shown whilst maintaining the flow and connection of the curve? Thank You all SkinningCurvesProblem.hip
  3. Hello there ! I'm looking for a way to replicate the "prune small skin weights" of Maya into Houdini. I've found the capture correct node, in which I can clamp the weights. The thing is, the bones are still weighted to the points, just with a zero weight. I want the bone to be removed from the list altogether. Is there a way of doing that ? The "Regions to Remove" field sounds promising, but I haven't been able to do anything with it. If you can answer the previous question, then the rest is not usefull anymore. But if you can answer it too, I'll be a happy little Houdini user grateful. Instead, I tried to do it manually. I dropped down a capture attrib unpack and a python node in which I recreate the arrays without the zero-weight bones. The thing is, I can't find how to create an array attribute on the points ! What is the correct syntax ? I've tried node = hou.pwd() geo = node.geometry() geo.addAttrib(hou.attribType.Point, 'myAttrib', [ 1, 2, 3 ]) but this creates 3 attributes myAttrib[0] myAttrib[1] myAttrib[2]. Thanks ! delete bone from skin.hipnc EDIT : Real-time update : Figured how to create an array attribute : geo.addArrayAttrib( hou.attribType.Point, "myAttrib", hou.attribData.Float, 1 ) geo.addArrayAttrib( hou.attribType.Point, "myAttrib", hou.attribData.Float, 1 ) But now I've got to figure how to populate it.
  4. Hi guys, I'm having some trouble using bone length for squash and stretch as its giving me crazy deformations that I cant fix. (see attached file) if anyone knows how I can solve this, it would be much appreciated. Also, the other problem is, how would I implement volume preservation with the squashing and stretching? In maya, we would use the joint scale but Houdini seems to give weird results if I scale bones. Any help is much appreciated. Thanks. rigging_bone_stretchy_problem_01.hip
