  1. This is my second Course, its available now on CG - Circuit. Link: http://bit.ly/2xk1Lzj Procedural Hardsurface Design in Houdini In this course I will show you different ways in Houdini about procedural hard surface design. The first chapter is about the Voronoi node and how to create different patterns with it. The second chapter deals with a simple hard surface tool to use the existing topology for creating new surfaces. The third chapter will show you how to use noise as a panel generator. In the fourth chapter we will build a greeble solver to refine large structures. The last chapter is about the process of a procedural robot that is made with different shapes and lines. Each chapter includes some RnD rendering in the end. I'm glad to share this knowledge with you! See you in the course! For this course you need a basic understanding of Houdini and rendering with Octane. All project files and the low poly character are included. Have a nice day and enjoy the course! timcgi
  2. Procedural Fractal Spiral

    Hey guys, I have been scratching my head for a while with this. I've researched online, tried to use geometry deformers, attempted boolean operations with concentric spheres, even migrated to 3ds max because I remember some modifiers that created similar effects. I've had no success and I am a bit desperate. I want to understand the system at play in the images below. I hypothesize that you start with very simple geometry, namely some parallel planes that then are deformed to achieve this amazing effect. My other idea, as I explained earlier is to create concentric spheres that are then "cut" by a solid geometry that has the inverse of this shape. If any one has any tips, pointers, references or resources that could help me figure this out, it would be much appreciated. Thank you so much in advance for preventing more hair-pulling. Cheers, Bruno

  7. Ball(clew) of wire

    Hello, there is a task to make a similar ball of wire (the wire fills a limited volume, keeping in turns), ideally animated (show how it roll up) What i want to get: I achieve this result (far from optimal, using popinteract with popnet): As I understand it is necessary to move towards the simulation of the rope.
  8. Procedural Modeling Advice

    Hey guys, after exploring most sides of Houdini, I'm surprisingly trying to settle on Procedural Modeling as my main focus :D I know it's a bit weird since it's not Houdini's strongest tool, but before Houdini, I have tried Modeling in Maya and Cinema 4D and failed, but with Houdini, it seems so logical and straight forward to my mind. I'm trying to get a job as a 3D Modeller using Houdini here in my country (Egypt), and i need some professional expert advice from you guys on some points regarding the market and Modeling in general (worldwide not just a specific country): 1- Is Houdini used widely in Modeling in the market or not yet? and why? and how much is Procedural Modeling popular nowadays in Games and Film as well? 2- I dunno much about texturing and I'm planning to learn a texturing software besides Houdini, so far I'm choosing Substance Painter, do you guys have any advice regarding this part? 3- Is Mantra good enough for me? Or do i have to dive into other renderers later? 4- How to constantly learn and upgrade myself in the right path? What else to learn? If you can give me advice from your professional experience, that would be great. 5- Any other advice you could give me is welcome, even abstract ideas, anything really. 6- One last thing There are different ways to approach Modeling in Houdini, i know that all methods are correct, but as a professional, do each one have like a standard method to approaching weird curves and irregular shapes efficiently? or you mix and match different approaches? Do you usually do low polygons baring in mind to subdivide the whole thing in the end or you can just model it all high quality from the beginning? I mean, how do you think and set your mindset before starting your work? :D Sorry for the long long post, appreciate your help guys. EDIT: I'm not a newbie who wants to explore Houdini, I'm already familiar with it and with all the resources available and I spent some time learning it. I'm seeking professional advice from experts because I'm applying for Modeling Jobs these days and i have 0 working experience in 3D.
  9. Procedural Scale

    Hi Everyone, Question Time! I have a curve in a helix shape. It has been made procedurally so the number of coils and length etc can be modified I would like one end of the helix to be stretched out more. Is there a way of procedurally scaling a part of a curve perhaps with a ramp? Any thoughts would be really appreciated! Thanks!
  10. Hello, I'm wondering how to go about this... I have a circular copy of boxes (merged) that I want captured from bones I have generated from a python script (script just makes bones for each copy of the object). I was thinking I could do a for each piece and do a capture proximity for each object and then after the loop, do a bone deform. But the proximity capture is capturing the other boxes as well. I want 1 bone to only capture 1 box. Not sure if i'm going about this correctly. The model is procedurally created and the number of boxes will change (causing me to run my script again, that will delete old bones and create new ones). any help is appreciated, thanks!
  11. Hi all, Relative noobie here, looking for general advice on how I might approach modeling a cancer cell that looks like this: https://www.mskcc.org/sites/default/files/styles/width_800/public/node/167374/3x2/sciencesource_ss21694540_1200x800.jpg [www.mskcc.org] or this: https://static.independent.co.uk/s3fs-public/thumbnails/image/2016/02/15/21/1-t-cell-corbis.jpg?w968h681 [static.independent.co.uk] One physical feature of the cell that I’d like to pull off convincingly is the sticky-looking tendrils that shoot out from the membrane, that look a bit like viscous liquid has been shot out from the surface of the cell. Though something like the image in the above links would be ideal, I would settle for something like this: https://lymphomanewstoday.com/wp-content/uploads/2018/09/shutterstock_565670083_zps0eglo9ri-1000x480.jpg [lymphomanewstoday.com] I would want to avoid something like this (where the tendrils resemble veins, or maybe octopus tentacles: https://www.segnidalcielo.it/wp-content/uploads/2017/08/GoldNanoparticles.jpg [www.segnidalcielo.it] Since for now I only actually need a static model, my first inclination would be to start with a simple POP setup, have some particles explode off a spherical surface and append a trail SOP to get the tendril trails. I’d run the sim and use a single frame from it as the cancer cells base geo. This only gets me so far though, as there are other important visual details that I’ll refrain from talking about until I some experienced person can tell me that this is definitely the way to go. My other inclination, which I realize might be inviting insanity, is to create a “fluid explosion”, using a FLIP setup with some velocity noise coming from the SOP level, and playing with DOP node settings to get the right kind of viscous/stringy effect from the particles. From there, again, I’d run the sim and use a single frame of geo for the base for my model. I’ve so far made an attempt at this (file attached), though have only tried seeing what I could get by using nothing but some noised-up velocity on the SOP source, some DOP gravity and tweaking settings in DOP Source Volume and Solver nodes, pertaining particularly to viscosity and surface tension (though I’m not sure the latter is relevant). I’m able to get some neat looking effects, but not really the ones I’m specifically after. What I’d wonder here is whether this ‘explosion of viscous fluid with a very high tensile strength’ could even be achieved with a fluid sim, and if so, would I need to push/pull the “sticky/stringy” fluid outward by having the FLIP particles stick to a set of “collision” particles which are then launched outward, pulling some of the fluid along with it. Or, could this effect be achieved by simply applying velocity to a Fluid Source SOP with very low particle separation, and then relying on settings available in DOPs nodes to get the long / stretchy tendrils. In any event, I’m certainly open to suggestions even if they’re completely different approaches to what I’ve described above. Thanks ahead of time to anyone responding!

  12. Hi all, I am working on a project that has pages of a book flipping with camera on top. Audience will be able to see the content on pages. I have already created animation of pages flipping. Problem is to assigning 10 different / unique page texture content wise to 10 pages of animated book. What is the best solution to do that. I am using copy and transform to define no of pages. Any pointers will be helpful. Thanks in advance.
  13. Hi folks, I was able to do alembic transport from Houdini to Maya for a scene which has a procedural vine/plant growth, how do I go about to maintain the UVs? kind regards, Clarence
  14. Hi Guys, For a tool i'm working on i need the radius of my metaball to be affected by the size of a painted region from a terrain, can anybody suggest how this would be done? It needs to change as the user paints but i'm getting stuck on the exact terminology of the code i would need to type into the region field on the metaball, this is what i currently have typed into the radius field on the metaball but it isn't working: getpointbbox_size(/obj/leaf_pile/"bound1", 0) Any suggestions would be greatly appreciated!
  15. Procedural rocks carved in vdb

    Hey guys, I'm trying to understand how to make procedural rocks carved in volumes using the technique exposed at Siggraph by Saber Jlassi. You can find the video here Hi approach is to use a combination of worley and aanoise in VOP. The result should look similar to this image. I joined the image of his vop network too. I didn't manage to reproduce what he is doing, been trying all day. Is there anyone here who would be up for giving it a go with me ? Any help would be very much appreciated. Chris
  16. making primitive from closed curve.

    Hi, I'm Edmund and I'm beginner on Houdini. I'm trying to procedural road and block for city. Is there any way to making primitive by using closed curve or something?(attached)
  17. Complexity from simplicity

    I am still amazed at how quickly you can build complexity with Houdini. This scene has just a few nodes - sphere, spring, add, copy stamp, poly wire - and result looks rather good, even if I say so myself
  18. I came across some really interesting procedural hard-surface topology here: https://www.instagram.com/mglhs_com/ He's definitely using Houdini for the workflow as seen in this post - I've been trying to figure out a workflow to generate fractures with workable topology but without success. When I try to push the boolean SOP with outputs from fracture SOPs anywhere near the kind of detail/shapes he's getting the geometry totally breaks down. It doesn't look like he's using any VDB workflow, based on the video it looks like it's purely mesh-based. Is anyone here able to get a better read on the approach he's using to get those kinds of clean fractures, gaps, and mesh separation?
  19. 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
  20. First dump from a home-brew Grammar system expressed iteratively as an evolving growth system. A decade of hunting down Blackberries to their roots - to remove them from my yard; A month of looking at and sketching Blackberry growth in the wild. A day with Houdini Apprentice, and a single point of geometry to seed the system. Then just turned it on. There's fewer than 100 lines of code, and I'd guess about a dozen substitution rules in the grammar system. Emergence is an effective approach for modelling organic processes. Blackberry_h17.13.hipnc
  21. Procedural Modelers at Zoox

    Zoox is expanding our Tech Art team and is looking for Houdini artists to help build out large procedural cities. Here's a link to the job description https://jobs.lever.co/zoox/67ccf836-fa7c-4d8c-9ff9-6eeb14c251b8 and here's an article talking a little bit about our company https://www.wired.com/story/zoox-self-driving-car-video-san-francisco/ Cheers, Doug
  22. Hello everyone! I'm trying to create a futuristic UI in Houdini 16 for a live-action shot. The "control panel" area is meant to be curved and inclined so the character can "use it". What I want is to scatter on that surface a bunch of random GUI element, but the problem is that I don't know how to make those object follow the surface curvature. In the image attached I scattered a single point at the center of one panel area and gave the normal direction of the faces + v@up, then I use Ray SOP to make it stick on the surface. As you can see the problem is that the text (or any object) doesn't bend. Is there a way? I tought of a some sort of linear interpolation of spherical interpolation but it's too complicated yet for me so I ask you if you have a better solution Thanks in advance!

  25. The Artist's Guide to Technical Direction in Houdini - Volume 0: Hscript Back in 2005 I got my start as an intern at Side Effects Software Inc. Over the past decade of using Houdini, I've worked around the world in the film (Starz Animation, Dr. D, Digital Domain) and games (The Coalition, BioWare, EA Motive) industries. In this time, I've had the pleasure of working with many artists who were new to Houdini and sharing some of the insight I've gained. While most people are pretty excited to get their hands on the flashier parts of the software such as FLIP and Pyro, I think that Houdini's greatest strength comes from it's sheer flexibility. And that flexibility is something that only opens up the deeper you delve into how things work. What I like most about Houdini is discovering new ways of doing things. One complaint I've heard time and again, is that after following a tutorial, new artists are often left with something that looks pretty but with little understanding of how anything actually works. I'm always hearing complaints about how steep the learning curve is with Houdini. I'm seeking to help fix that with 7 hours of new training material that focus specifically on HScript scripting in Houdini. This course I've designed for artists who are either lacking a technical background, or who may have experience in other packages but want to understand Houdini better. We'll avoid creating pretty things in this series. Instead, I want to keep a sharp focus on how things work. That means learning about procedural networks, variables and attributes, functions, and for-each loops. Most importantly, I address how to self-learn Houdini. My hope is that this course will build a solid foundation for you to get the most of any future training you pursue and help you to understand how to get the most out of your Houdini networks. If you'd like to become more adept at scripting in Houdini, please consider signing up for my course: https://mixtrn.com/course/the-artists-guide-to-technical-direction-in-houdini-hscript/ Have a Great Day!
