  1. Does anybody know how to use a group name as attribute class (attribclass) in a function like nuniqueval???? In the docs it says it is possible: attribclass One of "detail" (or "global"), "point", "prim", or "vertex". You can also use "primgroup", "pointgroup" or "vertexgroup" to read from groups. I can't figure it out how to use this thing, it doesn't work. Basically I want to find the number of unique attrib values from a group of points, not from all points in the geometry. For example I did something like this (point groups with the name of the primitive are created earlier) string grp = sprintf("primnum_%g", @primnum); int islands = nuniqueval(0, grp, "island"); i@islands = islands;
  2. With vector mypt you're kind of finding how many small boxes fit into a bigger one... But distance from a point to that vector (mypt) doesn't make any sense. You should start from this.
  3. Yeah, it kind of makes sense but in the event of a crash shouldn't Houdini just write a crashed file in the Houdini temp directory and leave the original file intact on disk??? I mean (if I think about it) it would mean that a scene crash it would affect the files stored on disk which is kind of absurd.
  4. Hello everybody. I've encountered something very troubling. I've had a few locked nodes (basically nulls) holding some pieces of geometry in a hip file. And now that I've opened the file after a while the nulls are still there but their content is zero. Basically the nulls lost their locked content. If this is a bug I think it's very serious. I need the locked geometry as an example input geo for various stuff. It is a bug or what? Can I do something to bring back the geometry?
  5. Hello Andreas. Is RISE FX still looking for Houdini people? I've sent an email (admittedly an extremely short one) to jobs@risefx.com but I haven't gotten any reply.

    Roof Generator

    Hello. Lately I received a few calls from people asking me to make a tutorial or release this method in some way (maybe unlock the asset). And yes, I was (I am) thinking of making a tutorial but this will take some time. Unlocking the asset is another possibility, I'm not sure... What do you mean by "reversed straight skeleton" and what you'll be using it for (if you don't mind the question)?

    Thank you very much! Well, if you are talking about this last post with the weighted solution then no, it is not completed for now, it needs some more work to be usable. I hope I'll be able to finish it soon. If you are talking about the whole thread then yes, an older variant of this this roof generator is on Orbolt for quite some time now
  8. Just for starters, you are using some kind of instancing or something like that, right?
  9. I fail to see the benefits of what Mantragora did... What's the point of skinning the tube in longitudinal, alternating pairs?

    Well, I managed to turn this into a weighted solution. Now every edge can have a different angle (even negative ones, which goes outside of the contour)

    Roof Generator

    Hello guys, I have an update to the roof generator that I want to show you. Now it can make gabled roofs. Gables doesn't need to be on rectangular sides (90 degrees etc), they can be anywhere. Also multiple (chained) gable walls are supported. See the images. I marked with red the sides that will become gables. There are a few minor problems to be solved, though. Ps: in case you don't know, this tool has been on Orbolt since April. In case you played with it like for example Freaq wanted, maybe some comments are in order...
  13. Well yeah, thank you both. Indeed, like Acey said, the y coordinate can be ignored in this case. I went with the dot product in the end, It felt better suited for the task for a number of reasons. Also I felt that the atan2 solution is less accurate. Working on this thing I learned that it's better not to test if some value is equal with 0 but if is smaller than 0.0001.
