  1. Learn Houdini through Video Tutorials

    Hey, everyone ! I know some of you are having hard times looking for a good Houdini tutorials? Found a really cool website with video tutorials. I like the author of the tutorial, he explains everything very clear. Just in case someone will need video tutorials , here’s the link to check full list of his tutorials: https://www.cgcircuit.com/instructor/tyler.bay Hope it helps! Best, Chris
  2. This is a bit fx, a bit modeling, a bit rendering, so I'm throwing it here-- I am running sims on a tree model. The original tree was too hi-res to simulate, so I had to run Clean and Remesh to reduce its poly count a little bit. It still proved too oddly-modeled to run a point deform on the original based on the sim, but the sim'd model is still high-poly enough so we're going to use it as the final. What I need to do is transfer the UVs, in world space, from the original model to the down-res'd sim'd model. I tried using Maya's Transfer Attributes, which does exactly what I need, but choked on the source model's size. How can I do this in Houdini? (I know there will be some changes, but those should be mostly in the little tiny branches that are okay to lose, and this is not a hero tree.) I assume it will be something like storing the original models' point positions and then somehow applying those points to the end result of the sim'd/cached model, at which point I could do a straight attribute transfer (and although I get this theory I don't know the steps required), or is there a better way (and if not, how would I do my suggested way)? Thanks so much!
  3. For the full course, be sure to visit this link: http://bit.ly/2EacZM5 Welcome to Houdini for the Artist - Modeling I This course is designed to help you get comfortable with modeling in Houdini. Like always, we'll take a hands-on approach to learning things by creating each item with a specific purpose in mind while exploring a variety of technical and artistic considerations along the way. Some of the topics include: procedural modeling, traditional hard-surface modeling, the terrain tool-set, curve-based modeling, and how to interactively build things within Houdini's viewport. With the developments made in Houdini 16 and 17, Houdini's modeling tools are more accessible than ever and can offer a lot to anyone interested in modeling, vfx work, tool-creation, hobbyists, and people that are interested in getting to know Houdini much better in general. If you come from a traditional 3D artist background like myself, this course will certainly make Houdini's modeling tool-set feel much less intimidating, and for technical artists, it also provides great insight into various modeling methods that can be used as a springboard to further pipeline & tool development. In addition to these videos, you'll also receive useful resources such as the Houdini modeling cheat-sheet - a helpful collection of hotkeys & relevant interface information. Plus, you'll also get access to extra scene files which help in expediting your learning with the terrain tool-set and for-loops. Thanks for watching! And for a couple of free sample lessons, be sure to check out these videos about for-loops:
  4. Hey OdForce! Lately I've been doing weekly quick-tips that I'd like to share with you all. Be sure to follow me on youtube & vimeo for new videos. Also, keep an eye out for my new course - Houdini For the Artist - Modeling I which I'll be finishing up shortly. Cheers,
  5. Roof Capping Techniques?

    Hi this is my first post and I've only been using Houdini seriously for around a month. I'm creating a house builder procedural asset to assist in the development of a VR experience because a large number of buildings need modeling in a short time. I started with the video by Konstantin Magnus on Roof building, and have just been adding more detail. Currently I'm stuck on procedurally creating roof caps like in the reference image. I've gotten as far as getting an edge group from UV seams, cleaning it up to remove overlaps and sweeping it but I'm not sure how to get it to align to the roof and offset a little bit. Ideally I'd like to have a tiling texture on these caps. Maybe I'm taking on something too complex for my level of experience. Any help, criticism, advice would be appreciated. TLDR: How to get roof capping like in the reference image procedurally? HouseBuilder14.hiplc
  6. Hey OD Force, Decided to try and use Houdini 17 with HDM as my main hard surface modeler. Coming from a highly customized Maya set up. Is there a way to select an object, and run a "select similar" command. For components, it would select similar faces / edges / verts if the component had some type of symeterey (such as right vs left, top vs bottom,) For objects, it would select similar objects that have matching topology / bounding box volume. If more than 2 objects are select it woud select all objects in the scene by type such as poly objects, nurbs, etc I know at some point I would need to figure out a branching template for python commands, but to start, is there a select similar command?
  7. I`ve done negative polyextrude to have cutter for hollowing my mesh. I wan`t to have thin layer (few mm). Whole item is about 1-3 meters. I`ve done it in way: - boolean as surfaces to slice intersections - polyframe to group areas to select it manually and delete unwanted strips (as islands) - intersectionstitch to stitch raw areas after deleting strips (to have one shell mesh) It works but I wonder is there any better way for that (for removing intersections and stitch corners)? That final stitched mesh will be boolean cutter (negative) for positive original mesh. At the beginning I`ve started to play with IsoOffset but it was too heavy operation and It took too long. So that`s why I choose PolyExtrude. Other thing is IntersectionStitch node. I don`t understand why I should feed curve for it. I don`t unsderstand also that warning: “A triangle and curve mesh is required on the input for correct attribute output.”. What I`ve lost If I do not fed up IntersectionStitch with curve? Why I need those curve if final effect is good for me. It`s a bit strange becouse after IntersectionStitch I wanted to use Divide node to change most triangles to quads but It is not working. Nothing happened. So I feel that something lost during those IntersectionStitch. Thanks for any help. I`m basic Houdini user (I want to port my modeling from other 3d app).
  8. Hi all! I'm trying to make a Voronoi fracture based on points that are to be scattered on the volume running along the border, in a gradient fashion towards the center of the geometry. The idea is to use the points for a 2nd layer of Voronoi fracturing after the main pieces are defined. I know there is the density attribute to drive the scattering, and you can use a volume wrangle to define the density attribute, but how do I tie the attribute to each voxel's distance to the center? Ideally, it would be the distance of each voxel to a smaller copy of the geo, so that the density gradient is uniform and not stretched to reach the center from far-off parts. Is there a way to do this? Thanks!
  9. remove geometry intersection

    Hey guys i was wondering im coping geometry and the geometry is intersecting im traying to solve this with the intersectionanalysis sop that yields a primitive number so i want to delete the connected geometry that the intersectionanalysis sop said theres interesection i connected the copy to a wrangle and the second the first input is the copy the second is from the intersectionanalysis sop im having truble with the vex code , i suck at it the copy sop yields group outputs so i thought to take an advatege out of it so my code looks like this now int list = point(1,"test" ,@ptnum); string groups[] = detailintrinsic(0, 'primitivegroups'); foreach (string g; groups) { if (inprimgroup(0,g,@primnum)>1) { removepoint(0,@primnum,0); } } list is the second of the numbers from the array that intersectionanalysis sop yields its not the whole of the array because i think i dont need all of it to be honest im really lost and one knows the solution
  10. 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. hi! would anyone know where to start with modeling something like this? https://www.shapeways.com/product/JUND48994/3d-400mm-orb-of-life-3d-flower-of-life?optionId=40619997&li=marketplace seems like a copySOP to create a new circle curve at every intersecting point, but how to get the curve to adhere to the surface of the underlying sphere? thanks in advance! matt

  14. Polywire shape adjustments

    Hi there! I'm trying to add a certain shape to an object. (see image which hopefully explains it better ;-) the effect I'm trying to achieve is that the polywire should be bigger to the point and smaller/thinner in between. I did try it with a ramp but it obviously doesn't work. I'm still new to houdini and any help is very much appreciated! Thanks ;-) curve on object.hipnc
  15. 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.
  16. Grid Subdivision Problem

    Hello, i have been encountering this subdivision problem during the modelling process,i tried using edge loops but they won't solve the issue. What i also don't understand is why does it only happen on that particular corner? Thank you for time
  17. Hi, I'm trying to remove part of a sphere with a bunch of other spheres that I converted to vdb then to polygon to use like metaball and have a single geometry to use to "cut" the other one. Thinking (silly me) it would make it easier. if I switch the input of the Boolean node it kind of work, but I need the reverse of it. It was working great with the cookie SOP before. but I'm guessing new node require new workflow (which is fine, I just haven't understand it yet).:) The boolean node is giving me a warning "NonManifold edges in solid...pnumbersnumbers" I added a Clean sop afterward to try to fix it but no luck, I included my hip, if anyone of you nice people could help or point me in the right direction it would be much appreciated. I also attached the intended result, which I got with the cookie sop a long time ago. thanks SplashScreen01.hip
  18. I am trying to learn how to make a procedural building but I don't know the best way to apply windows and doors to the walls. I can use CopyToPoints to apply my components to the walls but if the component has a surface that is inset deeper than the wall, I need to use a boolean node to remove that part of the wall. The procedure that I have come up with involves using two CopyToPoint nodes, though. One to boolean out the wall and the other to apply the component. I doubt this is the best way to accomplish this task. I would appreciate a suggestion for how to do it the right way. TestBool.hiplc
  19. Using Bend in Houdini

    I need help with using the Bend feature in Houdini 16.5. I need to be able to bend a tube or cylinder-like structure in a couple of places. I have never used Houdini or any other 3D modeling software before. I know absolutely nothing about 3D modeling or associated software. If anyone can describe how to do this, I would really appreciate it. I have spent many hours searching tutorials and videos, but none of them are specific enough or they are too advanced for my skill level. Since I have no knowledge of how to model, please explain things as if you were trying to teach it to a monkey. Resources with extremely in depth tutorials for beginners is also appreciated. Thanks in advance.
  20. Is it possible to show wireframe on subdivided geometry (with "+" hotkey) in Houdini 16.5? https://s9.postimg.org/64077xehr/2018-01-20-090918_1920x1080_scrot.png
  21. Prevent destroying Edit SOP

    Can I prevent somehow deleting Edit SOP when entering other state with unchanged geometry
