  1. Mechanical Linkages

    Anyone built multiple pivot mechanical linkages in Houdini? How would you IK this? I guess you could just mathematically constrain everything... but then you're working backwards from a known to make it work, as opposed to just arbitrarily connecting and changing pivots and lengths, and then seeing the result. I included a pic, not sure if it'll show up. If not, it's just an umbrella arm.
  2. Turn string values into numbers

    That's great Thx! T
  3. Turn string values into numbers

    A hack I figured out is to convert the strings to their UTF-8 code and add each array position plus and offset to get a unique number for each string. A benefit is that similar names are numerically close together. T
  4. I have a point cloud with a string attribute "name" and unique values, like C, C1, N, VAX, etc how do just turn each unique name attribute into unique numerical values? so all of the "C" would be 1, C1 would be 2, etc input point cloud will change and so will the actual names. Could be hundred of unique names. Thanks T
  5. @group_group1 = @name == "piece0-0-4" works, but not @group_group1 = @name == "piece0*" what am I missing? Just trying to group by everything that has piece0 somewhere in the name. Thanks
  6. Procedural Roof

    oops didn't see Konstantin's post.
  7. Procedural Roof

    That does seem to handle all of the variations I have thrown at it. Is there a similarly easy way to raise the elevation so everything stays planar? T
  8. Procedural Roof

    Has anyone attempted a procedural approach to this: https://www.youtube.com/watch?v=U8heCLYY_8I Basically a standard hip roof generator, but with some potentially sophisticated decision making. T
  9. Houdini Fuse vs Maya Merge Verts

    I see, Clean check Fix Overlaps, uncheck Delete Overlap Pairs.
  10. when you merge verts in Maya, it removes the faces. i.e., a rectangle cube becomes a rectangle plane. How do you do this in Houdini? "Fuse" keeps the prims. Am I missing a setting to remove them? Is there a different SOP that does this? Thx T
  11. Resurrecting this thread, cuz when I adjust the window size, my 3D objects and my background image no longer line up. Sometimes you need to zoom in on a section of the plate while working through the camera. This doesn't seem possible. Am I missing something? Also, Overscan? in maya I always worked some gutter around my render crop. Check the box, make it 1.5 or something. Helpful when your monitor isn't the aspect as the render, which is always. Is this possible? Hard to search the docs when I don't know what that would be called in Houdini. T
