  1. Hello, i am relatively new to Houdini and i would like to ask the community for methods to find a solution for my following project. So far i've been working mainly with C4D and Blender. I would like to find a workflow to create tree shapes from 3D models. Specifically, in my project i would like to take posed mesh from DAZ3D of 2 hugging humans and basically turn them into a "wood sculpture". (probably 2 seperate intertwined tree trunks) I would like to find a way to do this procedural, so i can use this on different shapes in the future. For now my focus is on creating the shapes, not texturing. So far i found 2 guides that might help for an approach: 1. 2. Guide 1 is a great approach, but the branches are too small and look like veins. Also the human shape is "too visible". I am looking to create a more natural tree look with really thick, wild growing branches. More like a tree that naturally grew into the shape of a human by chance. Guide 2 looks like a great way to approach the tree bark displacement, but there are only rock shapes shown and i sadly cant find a guide for a more organic, wood-like look. My guess would be to find a way to combine both of these methods, but sadly my experience in Houdini is too small to find a solution by myself. I'm looking to create pretty much this exact type of tree shape: I found this image under the keywords "foxtail pine tree", after searching for twisted branches. I hope someone can give me some tips to find a solution to realize my vision for this project. I am highly convinced there is a possibility. Really looking forward to what you guys have to say!
  2. http://www.patreon.com/posts/31506335 Carves out polygons using a point attribute with the ability to define the carve values per primitive using primitive attributes. Pure VEX implementation, 10x faster than the default Carve SOP (compiled). It preserves all available attributes. It supports both open and closed polygons.
  3. Hey everyone, I'm a generalist newcomer, I've been lurking for some time around Houdini and lately found some time to get into it. I decided to start my learning with a classic, procedural rock generation, I've been following some nice tutorials with good results (youtube.com/watch?v=2oC9TOgQ3KE youtube.com/watch?v=-IcOKBNNfyo&list=PLNbgmFvU__fiEIv-g12l5KDiW1YAH9MRt&index=2) So I decided to do my own version of it and I wanted to recreate this kind of silicon mineral, because I find the form of the surface (and material) really fascinating. Now, I think the general setup from the turorials I followed gets me in the right direction for the shape of the rock, I can get the sharp edges and all. What I am struggling with are the smaller details, the tiny grooves that follow the direction of a face, the diversity in the surfaces the fact that some faces stay smooth while others are sharp and jagged. The tutorials I followed use vop noise layers (both vdb and geometry version) to generate details in the form, but I cannot seem to find a good combination of noises to get close to tis shape. I am even wondering if the vop approach is at fault here, and maybe I need to try something else for something like this. But I don't know what exactly. So I wanted to ask fro help and advice from the more experienced users, let me know if you have some ideas or knowledge you can share on this problem!
  4. Hi, I was wondering if anyone knew of an approach to procedurally have a pen write up effect like the attached video? Few thoughts on the experiments I did - Tracing a font or an AI file results in text outlines and ideally it would need to generate a single curve possibly in the center of each Alphabet to even start with the effect, not sure how to go about that. Thanks! Pen Write up.mp4

  6. hello all, iam just dong a wall tool but i found that if my line is in curve shape i might get some gaps in-between the bricks. is there any way to fix these thing and i also found that some of the bricks are intersecting with each other. it will be a issue while doing RBD. is there any way to fix these things
  7. Hi guys, I'd like to share my latest personal r&d project of creating procedural assets. Still work in progress. Cheers, Shawn

  11. Hi, I am not sure how to explain this well, so apologies in advance. I have this basic cactus generator, there are clusters of thorns, at their base the thorns intersect with each other, which I currently don't mind, because I will solve or hide that later.. However I don't want the tips of the thorns to intersect with the tips of thorns from other clusters, as this is easily observed. Is there a way to place each thorn or cluster of thorns after the other and check if there are any intersections, after a new cluster has been placed and if yes rotate and maybe scale the intersecting thorn(s) until there are no more intersection? Like that cycle through all the clusters? I know my scene might not be set up well to do that.. Would that be expensive to calculate and/or difficult to implement? I attached the hip file, and an illustration to clarify what I mean: base_cactus.hiplc
  12. Hi All, I'm looking for some advice on something I’m struggling with. I have been looking into procedural building creation, and I’ve seen two approaches; make a procedural building which can then be scattered, or use Lab Tools Building Gen - with OSM data, and use a kit-of-parts solution. I’ve done some proof-of-concept tests with both options, but they both have limitations. The first option gives you random variations - albeit in a limited way, because the variation isn’t completely controlled. The second option - with Labs and OSM, definitely gives you more control over what you’re creating, and enables the layout of actual locations. The problem is I want to make a residential neighborhood with a specific style of house, these are all either 1, or 2 story homes - please see example attached. So far, the biggest issue is I can't find any explanation of how would handle the sloped roof procedurally. The Labs/OSM solution is great for cities, where buildings mostly have a flat roof - this works really well. I need to create variations of a certain type of home where some have bay windows, some have a porch on the ground floor - some all across the front, some only half-way across. I can add specific variation to individual buildings using either hand-placed overrides, or volume overrides. But it's the roofs which vary based on the footprint of the house that I cannot fathom - so different for each house, and I need it to be procedural. Does anyone out there have any suggestions on how I might best approach this, as I’m hitting a dead-end currently? Thanks in advance!
  13. Hi, I have been making procedural Lake House, after watching tutorial of Anastasia Opara, But the shape of my house is a bit different, I am facing lots of problems, I cannot find closed balcony of my house,the code finds others primitives, Please , help, here my hip file VEX22.hipnc , I think that the code of Anastasia finds only one primitive but my house has a balcony that consists of two primitives , Please share your experience
  14. Hello, I made this effect in Blender and wondered how would I recreate it in houdini, it's so that I can control how many segments I need without manually adjusting each one to avoid clipping. test1.mp4
  15. Hello and Welcome to HossamFX.org : Description : Hello everyone. and welcome to this course procedural City Vol 1 building generator . One year ago I received an email from one of my customers. He asked me To record a tutorial about procedural City in HoudiniFX and I did it In this course you will see with me how I can convert those boxes to this nice building Just buy one click. step-by-step I will start with you on this journey to see how we can create a smart system in Houdini FX. This system can decide where to add a window, where to add a balcony , how to create procedural UV, and How to use the imported materials from Quixel megascans , manipulate and modify it. Using this tool you can generate an infinite number of buildings. I will use those buildings in vol 2 to create a beautiful city. I will show you how to create every tiny detail you see in this building from scratch !!! I will stay away from complexity and the use of code . In addition to procedural modeling skills, this course will give you a broad idea of creating procedural UV’s and manipulating textures . Creating a PDG network is on our list in this course and the final render will be explored in Mantra & RedShift. Now I'll let you watch this presentation of the final result of testing this system to randomly generate 50 different buildings !!! Notice : Watermarked Tutorial, link to download will be sent AFTER 72 hours as maximum thank you !!! Course Link : https://www.hossamfx.org/procedural-building-generator Kind Regards !!!

  20. I originally made a post in in the WIP section, but have finalised a selection of images that demonstrate the extent of the project at this particular time. Hope to get some tips, speculation and direction . The work started with an idea of looking into systems of growth and the procedural simulation of that growth. The question of landscape surveillance and 'fertility' arose - can a landscape (or object) topology be evaluated for growth? In this case the landscape would be a scanned model of a terrain, converted from pointcloud to mesh data and thus reinterpreted as a topology of points and primitives with certain inherent attributes: Position (vector), Normals (vector), and curvature (scalar) predominantly. The simulation can then search for 'flatness' and eliminate areas of surface beyond a limit of acceptability. The surface is then displaced whilst maintaining ties to the remainder, this seemed to mirror a process not too dissimilar to inflation (although much more noisy and undefined), always using the retopologised mesh (and thus recalculated attributes) as a driver for the next frame of growth. Generated or grown form is evaluated through a series of spatial explorations with particular functional characteristics in mind. Much like a single-surface-landscape produces the massing for proposed architectural volumes, these volumes are then reinterpreted as single-surface forms that morph into a typology of architecture defined by certain rules. The primary purpose of the interior volume is to house the program of an architecture. The height of the form is predetermined in the procedural algorithm of massing to produce volumes within a range of heights (for example between 3 and 20 meters). The nature of the form suggests an architectural language of evaluated skin as a means of facilitating architectural space. This is then differentiated to provide for the various requirements of a space of production - for example: how can the floor surface serve as a platform for plant growth; how can the side envelope serve as a mediator of thermal comfort; etc? A. There is a desired differentiation between roof and side envelope - key factors to be considered are the issues of transparency in form for light to enter the space below and the capacity to drain rainwater or melting snow. B. An impression of uniformly distributed structural frames is suggested as a method of holding up a dressing of skin not too dissimilar to ideas of bone to muscle tissue connections. C. The form is interpreted as a skin multi-functional, multi-material character. There is a desire for a thermal envelope mixed with porous characteristics that allow for breathability within the interior environment, light, and mediation from the harsh external environment. The following images are all excerpts of a fully procedural exercise; all grown; but in various stages of development of the same system.
  21. Hi guys , I'm trying to delete the boundary primitives of a grid after using convert line node as shown in the pictures below with the help of VEX for procedurally deleting the boundary primitives of a grid . Thanks in Advance.
  22. 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
  23. 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
  24. 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
  25. 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
