  1. as far as I know, once it's been saved as non-commercial it's staying that way.
  2. " Is there by chance a way to use the Parameter Interface Editor, save that, call it from the script commit, and use the information from it? " that would be nice but i dont think its doable PyQt is the best way I know of creating custom UIs
  3. Create grey fibers ?

    a shit load of lines with noise?
  4. nice one cheers for the replies guys as ever - @anim's snippet did the business
  5. Having a brainfart here: I have a bunch of lines which I'm currently looping over and assigning the end points (ie. has 1 neighbour) into a group. What I now want to do is remove 1 or the other of these two points from the group. Someone show me what a donut I'm being, please!
  6. You could even make it a start/stop toggle: def outputPlaybarEvent(event_type, frame): if event_type == hou.playbarEvent.FrameChanged and frame == 1: #print event_type hou.playbar.play() hou.playbar.removeEventCallback(outputPlaybarEvent) return False if not hou.playbar.isPlaying(): hou.playbar.addEventCallback(outputPlaybarEvent) hou.setFrame(1) else: hou.playbar.stop()
  7. Add this script from Maurits to a keyboard shortcut and you're good to go. Not sure if Macros is something that can be done in houdini but you can definitely script this stuff.
  8. Vellum Hair Break

    I've managed to get the vellum hairs breaking quite nicely - but I wonder what the breakthreshold is compared against in order to determine that it has been reached. Any ideas?
  9. vellum hair break [SOLVED]

    hopping on to this one. I've managed to get the vellum hairs breaking quite nicely - but I wonder what the breakthreshold is compared against in order to determine that it has been reached. Any ideas?
  10. Vellum Hair Separation

    Anyone know how to stop this happening? I don't want the segments parting when stretching.........
  11. transfer attribute

    crank up your max sample count to 100 is that what you want? if the values arent strong enough throw down a wrangle with something like this in it: @Cd*=10;
  12. I'd like to be able to set a node's name based upon a separate parameter. Sort of like the opposite of $OS on a parameter. Is this something I'd need to write a callback for?
  13. Out from ROP otl

    I've made an otl that contains a couple of ROPs, ideally i'd like to be able to merge a few of these otls before submitting to the farm - what would be the equivalent of an output node for this?
  14. 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
  15. 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);
  16. Why is Mantra so Slow

    post your hip file. this is not normal behaviour
  17. 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?
  18. 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
  19. 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
  20. 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.
  21. scratch that attributeOrient does do what I want
  22. 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
  23. If it's just falling snow then points do fine
  24. Match Toplogy SOP

    I'm being a donut. Just setting input A P to input 2 P is doing what I want.......
  25. 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
