  1. 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.
  2. 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
  3. 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!
  4. 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
  5. 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)
  6. 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
  7. 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?
  8. 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
  9. 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
  10. 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
  11. 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!
  12. Hello everyone : Some test using my tool for creating procedural Tree growing and Rigging : Tutorial Trailer : link to Tutorial : https://www.hossamfx.org/trees-rigging-in-houdini/ thanks Hossam Aldin Alaliwi www.hossamfx.org
  13. I made a tool for creating fully procedural cave systems from curves for use inside UE4 with Houdini Engine. Check it out, let me know what you think. Available here: https://gum.co/hdacaves Enjoy!
  14. 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!
  15. Hello guys, I'm quite new here and recently joined the odforce forum. I don't know if there is any other category where I can get feedbacks hence posting here! Just when I was searching for cake recipes, I fell for the "Strawberry Raindrop Cake" and decided I should make one for myself! Link to the reference video: at 0:09 timestamp well, A "Raspberry Raindrop Cake" in Houdini ;-) Here is my progress so far, any feedback is appreciated! Thank you!
  16. How is this effect made?

    This effect at 0:16-0:20 is inspiring me to learn houdini. But what is called and how do I achieve this effect
  17. Hi! I`m looking into creating a digital asset of procedural trees, with the idea being to generate a hole bunch of pine trees that you can scatter in a background of a shot for example. I`m sort off lost in the whole procedural way, and the L system is way to complicated for what we are trying to achieve all though that might be something to look into in the future. Also is there a way of copying a line with different length the higher up it goes? Lets say you have a line 8 units long with 10 points, I have grouped every other points and want to copy another line on the grouped points, but I need the length of line to shrink with each copy Any tips would be much appreciated.
  18. Hey Came to London to work for Crowd at MPC. Here's a summary of the challenges I responded to in Houdini: At the moment, I'm looking for the next thing to hop on. Most jobs for Houdini are VFX centric and I'm mostly a generalist leaning more towards geometry, rigging and motion processing side of things. Here's some public Orbolt Assets: https://orbolt.com/search/?q=probiner Building one right now to upload, to alike the matrix one, visualize arrays of vectors: https://i.imgur.com/ZPki1XN.png Let me know if there's something fit mid-term going be it for Houdini or XSI or even just if you're around and want to have a chat! Thanks
  19. Made this a while ago, finally got around to uploading it to gumroad. https://gum.co/ofsD
  20. I am doing pcopen in cvex to to render points as volume but for some reason I am not able to scale the density as much as I want. It looks like it is clamping the density values and doesn't allow me to go higher. When I use smaller IFD bounds this problem fixes itself but also it cuts my overall object. Also vex volume procedural doesn't seem to work with new mat context. Thanks for the solutions, Alican
  21. Hi I'm still a beginner in Houdini and i decided to create a mini project to learn it and stay motivated. I want create a procedural train tracks. I would like to have the tracks follow a spline and depending on the angle and the lenght of the spline the system will place the correct blocks. I will build each blocks straight and curve separately. Here is the schematic of each blocks and a quick render i did in Houdini http://www.woodenrailway.info/track/trackmath.html# Any idea where to start ? Thank you for your help. Thomas
  22. Hi Everyone I'm currently trying to create circular point groups, inside a voronoi fracture. My outputs are groups currently are primitives but when I conver them to points, i have to many clustered together. I'm thinking of a solution by either getting the max/min two points of each primitive inside my group and delete the other points from the group. Unfortunately my VEX skills are very limited, I seem to be declaring my max function wrong. If someone could help me figure it out that would be great, also an explanation to why my attempt didn't work/ any other solutions towards achieving the same result would be more than welcome. Cheers Example.hipnc and for any questions im trying to make a tool that creates ground slams, as you can see there's distinct circular fractures which im trying to replicate, but also make procedural.
  23. Vex Volume Procedural Grid Rez

    Hi! I've found many examples with volumes using this render approach, but there is somthing I'm missing out. How does this VEX Procedural Volume gets its divSize/resolution? I've seen the "octree" option but it's another thing (An optimization for getting less render time) So how does this volume define it's grid resolution? I'm just curious!! Thanks.
  24. Hello, I am relatively new to houdini - I have used it years prior for some things but now I have just acquired an indie license for development of my unreal game. At the moment I am making a building facade system that will place premade modular pieces depending on a few variables. I was hoping that perhaps some guru's could peruse this little plan i have drawn up for how i envision it to work. at the moment I am trying to workout step 4 by using bounding boxes made from the original geo to select the new resampled walls and place them into sections. I want to bound them and in the groupSOP name the sections per iteration of the foreach node they are inside. finding the correct syntax for this has been a problem so any help would be greatly appreciated. Ill be keeping this thread alive over the course of my findings. Cheers Az BuildingGenerator.hiplc
