  5. Help: Instancer and Label

    is this normal of creating hda that you have (Mesh Instancer) + Main_Geo on the bottom? 1. Is there a way to just hide or delete the Main_Geo. 2. Is there a way to be able to changed the label of (Mesh Instancer) to your custom Label? Regards
  6. Procedurally Set Pivot for object

    Hello, For now I have learned to centerize the pivot but I just wonder is there any way to procedurally position the pivot? Like in this scene I want to setup the pivot properly at the begining of each leaf Thank you for your time. Pivot_Position_Ask.hip
  7. Hi everyone, I have a plant (leaf and stem) merged as one piece of geo with some dynamic animation. I'd like to animate the leaf separately and still be able to keep the current animation. Is there anyway you guys can think of that I could do this in a procedural way? any suggestions would be much appreciated. Even if you have suggestion on how I could do it differently from scratch that would be appreciated too. See attached file. Thanks in advance. philodendron_model_03_for_forum.hip
  8. instance chaining when point number changes

    Hi, I'm trying to instance different geometry on points, but the instanced object is chaning its object every frame, since the point numberis chaning, tried adding the id, I'm not sure where it got wrong, can someone help me here, copy_instance chaning_problem.hip
  9. Rotation in Wirecaptures

    Hi, the wire capture and wire deform are not taking the rotation of the points to rotate the geometry, attaching the sample scene file below, Basically, I'm rotating the curve and deforming the geometry using wire capture and deformer but it's just moving leaving the rotation Thank You wirecapture rotation.hip
  10. Hello, I'm learning houdini and so far I'm loving it but I'm having a problem to understand a concept of manually editting something that has already been generated. I guess this could be quite a common use-case but I haven't found solution anywhere so I'm trying to seek help/guidance here: I am working on procedural generation of buildings from their footprints. To simplify, I have a geometry node in which I have a foreach loop SOP that iterates over footprints (primitives) and extrudes them based on their height attribute. Now, is it possible to select a specific footprint and change its height attribute so that this specific footprint will be extruded by different amount? What I'm trying to achieve is that user is able to select any procedurally generated building and adjust/override its default/random parameters like height, roof type, texture... and after that - this building will be re-generated reflecting these changes (while other unchanged buldings won't be regenerated to speedup this process) Does houdini provide such functionality? Or are there any best practices how to approach this problem? Thanks
  11. Hey guys ! I've been struggling for a while now on this guy... That's why I'm hopping finding a hero among all of you ! I want to model produrally this mushroom shape. I try different approaches, but so far nothing successfull. The thing Im struggling the most is to get those smaller leaves along those organics kinda veins... The overall veins structure and the small leaves are all connected. I join the hip file in the post So if any of you have some guidance feel free to share it proceduralMushroom_odforce_v1.hip
  12. I'm currently working on a procedural book model with controls to open/close it, flip through pages and whatnot. My issue is that I'm not sure how to bend the pages using MOPS. I'm really enjoying how easy they make any kind of transform operation relating to instancing of any kind, but I'm still learning how to make them deform geometry. I hope I don't have to switch to a Copy Stamp + Foreach Loop workflow, but if anyone has any feedback or thoughts, I'd love to hear them! I've attached a few renders and a video of my work in progress. D__Personal_Houdini_Book_0001.hiplc_-_Houdini_Indie_Limited-Commercial_18.0.532_2020-09-27_19-42-42.mp4
  13. Nekiya

    Hello, I'd like to share a shortfilm that I've been working on for the last few months. It is set up and rendered entirely in Houdini; whilst some 3d models are drawn in other bits of software, the majority is procedurally drawn and the outliers also tend to undergo transformations. Strictly no 2d effects, everything is simulated spatially within the scenes (this is part of an ongoing practice ethos of trying to understand all geometry in 3d and render a fully composited shot). I am very excited to continue to develop and unpack a lot of the systems that have been built for this project. It would be great to get some feedback, thoughts and criticisms from this community. I hope you enjoy. LINK: https://vimeo.com/446918887 Cheers, Egmontas Description: Nekiya is a short film that constructs a spirit realm as a reflection on the naive hypothesis for the existence of ghosts. Who has seen the spirits? Neither I, nor you. But when the invisible weighs upon your chest, the spirits are reaching through. Let the spirits emerge and let Spookiness be true. As Spookiness has an overwhelming desire to meet Soba, she anxiously struggles to determine her place in this delicate world full of occurrences at the edge of her perception and control. Soba begins to doubt the verity of not only her constructed memories, her tears, but the seemingly indeterminate nature of her body itself. Spirits emerge as three-dimensional entities with embedded spatial, material and behavioural data that characterises their potential and inherent constructional capacity within what we can now determine as our multiple realities. These spirits are a consequence of procedural logics that inform both simulation and translation in a digitally pliable universe. Nekiya is the hypothesis of a haunted space of spectrality; it is an episode in the search for a practice of digital poetics.

    Any suggestions on the method to be able to achieve something like this?
  18. Procedurally split faces

    Hey guys, it's me again, I have another "complicated" question : is it possible to procedurally split faces with vex ? I'm modeling roofs, and I needed to split the top faces to get to and be able to get a triangle shape (by translating the created point on the Y axis). The edge divide sop makes a wonderful job, but sometimes it doesn't cut faces properly (it's very rare but very annoying). For now, I detect the bugged faces by counting the vertices on each face, and if one has 6 vertices then it's a bugged face; but I don't know how to split them procedurally. One method that came to my mind was making a python script that creates a polysplit node for each face with the split coords but it's not very efficient.. If anyone has an idea ! Cheers, edit : added a screenshot for a better explanation!

  20. procedural tile bathroom

    Hi guys, i would like to procedurally do this bathroom wall, but i'm stucked.. I used for each loop but i can't get random edge for each wall of the room.. Thank you for help.
  21. I've been learning a lot of vex over the past couple of months and this is my first real practical use trying to make a procedural tool. Let me know what you think! Next iteration is to add more curved lines using trigonometry instead of smooth. https://youtu.be/UsDpGrcrLhE

  23. Digisoup

    Hello, I thought that I would share a side-project I started this last month because I lost a bit of steam (no pun) and thought that it would be curious to receive some feedback. The Digisoup began as an idea to create a procedural recipe that creates and fills a bowl of soup with various ingredients. The initial to do: bowl, stock, dumplings, veg, seasoning, steam, etc. The bowl or vessel was modelled independently but used as a source object for the other ingredients. Spring onion, spices, chilli, dumplings, eggs and noodles have all been drawn within a procedural framework - I intend to do posts explaining each ingredient if anyone is interested. The stock (liquid of the soup) is primarily a shading exercise, and on that note all of the shaders are also procedural and do not utilise bitmaps or external references. The intention with that was to be able to control 'fattiness' or 'richness' of the soup we are about to enjoy. I haven't yet documented the entire process but here are some of the shots I've managed to salvage while working in progress. At some point the project began to evolve into figuring out the context around the bowl with some embedded procedural tricks - I will expand on this later! Would love to hear your thoughts! Cheers.
  24. Hi everyone, I'm trying to do something quite simple but i'm struggling with it. I have an imported pile of sticks, i want to take this pile and copy each stick to a different point on a grid, i know how to do this using the method of having each stick have its own geo node and pluging those into a switch and copy stamping them onto a grid, but i want to achieve this result without having each stick be its own node, as there are 214 individuals this would make for a very crowded network. Could anybody help me out? I have attatched my current set up, I am guessing I need to specify in the copy stamp that for each point it needs to select one of the 214 points which are being fed into it, but i'm not sure how to command this expression? Thanks in advance! Dbrs_wood_twig_T_rfkkwaa_LOD0.obj
  25. Subdivision fractals

    Hi, I tried replicating this type of "subdivided fractals" and figuring out how does it exactly works for 5 months now but with no success despite my best efforts. (this is the thing I'm talking about: http://www.michael-hansmeyer.com/platonic-solids , it is somewhat explained in the technical background tab, and a bit more info: http://www.michael-hansmeyer.com/subdivided-columns) I tried similar things with the kinds of smoothing algorithms mentioned on the website (Catmull-Clark and Doo-Sabin) but I never achieved anything like these things (or I jusk can't see a forest because of a tree in front of me after that much trying ) So if anyone has some info about how these fractals can be made in houdini I would be really happy to read it
