  1. Need help with loops and Foreach

    Would love to see it too. Really wondering how he makes that work with 2 for loops with the 2 switches. I'm also a beginner.
  2. Hi! I create these mountains on my shape with a noise by getting that noise by affecting the @P.y attribute. Of course the mountains are thinner when my shape goes more steep, because the points distributed through the Z axis are more dense there. To resolve this I thought I should use a different Pos for the noise, so I created a grid and put it in the second input. But when I use getattrib(P) on that input and plug it into the noise, I don't get the expected results. (It seems to do nothing much) Is it that you can't use differents Noise pos' like this? Does the topology have to match with the geometry or something? How does this work, exactly? How would one go about evenly distributing the noise position along the Z-Axis? So that you have just as thick mountains everywhere, no matter how steep? Hope you can help me. Thanks.
  3. Thank you. Seeing stuff like this really helps me get a better understanding of Houdini.
  4. Hi, I have created a object with groups, and when I copy it, I want to be able to acces each group on each copy separately, instead of all at once on all copy. Here I read that I could use these cool variables like $CY. Can I also use these to keep and rename existing groups? keep and rename groups.hipnc Thank you!
  5. Evenly spaced Z points in position Noise VOP?

    Thank you Twan. I think you mean flattening the y btw? I'll put my other post regarding this for reference here: https://www.sidefx.com/forum/topic/66556/?page=1#post-284703
  6. Could you maybe show me how you would do that in a Wrangle? Is maybe a For Each method better? As I read in the documentation that they have kind of become the replacement of the Copy Stamp I do not know much about For Each and Copy Stamping and I am going to dive into it now. I ask the example as it is something I would like to know in advance.
  7. Would this be the same as the current "Unroll U" stuff?
  8. Hi, I am currently follow cgwiki's JoyOfVex and also HoudiniVolumes from there, which I really like. I am currently not interested in using UV for texturing and stuff and I know very little about them, but now I see on the HoudiniVolumes page that I couldn't even color these lines, if they wouldn't have 'textures'. Seeing this and also that getting wireframes also to do something with UV (i.e. setting Ends SOP with 'close U' set to 'unroll'), it has become clear to me that I should really learn about them and understand what they are. I would like resources that are for beginners (because I am one), but I don't want them to be for beginner in the sense of "this is what you can do with them, now bye". I want to go down to understanding the underlying mechanisms very quickly. Hope you can help. Thanks!
  9. Hi! So I have this grid who has colours from a from a noise, and then I make them lines and jitter them. I have made an attribute on it called 'eye'. And I want at the end of the chain to color my object a predefined red (color vector) where the 'eye' attribute is 1. And I want this on top of the existing color, which is what I don't know how to do. How can I layer different colours on top of each other based on attributes in VEX and in VOPs (or any other way)? AddColorToExistingColor.hipnc Thank you!
  10. VOPs - output to @P.y.

    Nice! Thanks u both.
  11. VOPs - output to @P.y.

    Hi! I am trying to recreate some VEX code in VOPs, just for understanding. But how do I output to, for example, @P.y in VOPs? Thanks.
  12. Spherify New Terrain/HeightField?

    Any developments regarding this? I don't necessarily want a sphere, but I would like to create a giant floating island.
  13. Hi, Was wondering how this is done. When I promote the group to edges it also includes edges outside the outside. Thanks for your help. Pardon /// I thought I had clicked every button, but apparently something went wrong with me or with Houdini.
  14. Thanks. I'm gonna buy a heightfield/terrain course then, seems worthy. Would still like to know if you or anyone else found out how you can get rid of these spikes. Thanks again.
  15. Hi, So I thought I should get to know height fields today, because I have modeled object on which I want to make a terrain with mountains. So far as I understand it height fields are not 'real'; they are just visualisations of height based on the values of voxels on a 2D volume (slice). Okay, but is it also possible to put these height fields onto a existing geometry that is not flat? Is height fields the way to go for something like that? Thanks for your help.
  16. Modeling questions (remesh, polyfill)

    Thank you.. Skin would be a better method indeed.
  17. Hi, When I use a Remesh on my mesh, it doesn't do anything. Tried changing any parameter. Anyone has an idea why this is? Was also wondering why I can't choose quadrilaterals in my PolyFill. Help would be appreciated.
  18. Select Outside Edges Only

    Hi guys.. How does one convert them to edges?
  19. Hi! Was wondering how I could flip my top view, so that Z is points in the opposite direction. Thank you.
  20. Rotate orthographic (top) view?

    Okay thanks. But what if I want specifically the top view? Or if I want the top view 90 rotated?
  21. Neighbour count doesn't seem(?) to work?

    Allright thanks.. The example I had picked up here didn't have that. But it has 'input_index', instead of 'filename'? https://www.sidefx.com/forum/topic/13933/?page=1#post-65825 What did it do now exactly without this OpInput1 connected? Where did these 0's, 2's and 3's come from?
  22. Hi, I want to procedurally select the two end points of my shape. I read I could achieve this by counting the neighbours and using a group expression. You would think every point on my shape would have 2 neighbours, instead of only the two end points, who would have 1 neighbour. But I get very strange results. Lots have 0, a few have 3 and 2.. I don't understand it. Can someone please explain to me what is happening? neighbours doesnt work.hip Thanks!
  23. Is it also possible when you have, say, a shape like this? Can you cut out what's in the height field grid which is not the same is this shape (from top view, I guess)? heightfield on such shape.hip
  24. += in setpointattrib?

    Today I saw you can mix color using +=. (http://www.tokeru.com/cgwiki/index.php?title=JoyOfVex12) But now I wanted to test it in a case where I need to assign it on point numbers using setpointattrib, but I can't get this effect. Why does "add" create this overblown effect? And not just subtle mix (like +=)? Would appreciate your help. Thanks.
