  1. Figured it out! Plug one stream into the first port and one into the second of a wrangle: int match_pt = findattribval(1, "point", "id", @id); removepoint(0, match_pt);
  2. I have two sets of points and I want to compare them by id. If there are matching ids then I want to delete the matched from one of the sets. Any pointers appreciated. Cheers
  3. Why is Mantra so Slow

    post your hip file. this is not normal behaviour
  4. I'm building up a crowd for some stadium work - the mocap out of the box might wll do the job but it's only men - anyone know where I can get some women?
  5. Hi, I'm trying to find a way to export nested .ass files - for example with a crowd. I can get a crowd exported using alembics using this method - but I was wondering if anyone could point me in the right direction for exporting, say, each agent as an arnold procedural within a single arnold procedural i.e. nested. cheers
  6. Replace mPlay ?

    you can create your own - sort of - by writing to disk and then opening the written sequence with another app e.g. rv
  7. Anyone know how to stop CHOPs calculating everytime something upstream changes? Even if I remove it from the stream it halts houdini whilst it calculates.
  8. scratch that attributeOrient does do what I want
  9. A basic question I have some groom attributes on my rest geo, I then scatter based on density and so I want the groom attributes on the newly scattered points. I then attribute interpolate these points across to my animated geo. How do I get the groom attributes to follow across correctly too? I know the attributeOrient SOP does some of the work but not all. Any help appreciated. cheers
  10. If it's just falling snow then points do fine
  11. Match Toplogy SOP

    I'm being a donut. Just setting input A P to input 2 P is doing what I want.......
  12. Match Toplogy SOP

    Thanks Atom, That doesn't quite do what I want - the resulting geo does not match the deformed sim closely enough. This is because there's no useful frame to which I can freeze and make a rest. As I said - Match Toplogy SOP does what I want - it's just seriously slow once I start getting to the number of feathers I want to be matching. cheers

  14. Match Toplogy SOP

    I've run it through a Carbon Plumage sim, which has changed the prim order.
  15. Match Toplogy SOP

    I have two sets of geo - they have the same geo but the primnumbers have been changed in the second set. The Match Topology SOP does exactly what I want - which is to reorder the first inputs prims based on the second input, but it's very slow on a lot of data. Any clues as to how I can either a) speed it up or b ) build a quicker one? Tried using combinations of attribute copy/transfer and sort SOP but not to any success as yet. cheers
