  3. Photoreal Honeycomb help needed

    Hey ya'll, So I've been working on this photoreal honeycomb for a project and I'm not happy with the amount of detail I'm achieving. I'm relatively new to Houdini and I've been trying to use it as a Generalist package however as soon as I have to use any code I start to feel out of my depth. In saying that, my current solution is almost all procedural and all with nodes and no scripting. I have opted for using attribute noises and point VOPs to generate roughness, displacement/surface noise as well as using shader displacement/normal noise to get High frequency noise without having an insanely heavy mesh. I should mentioned I am using redshift to render currently. So my main question is how can I make this look more detailed and more photoreal? (I have provided a render of a test section as well as photo reference of the detail level I would like to achieve.) That test render is the starting point of a camera animation, so that is as close as I intend to get to the honeycomb. I was wondering if I should use a solver to get an organic growth effect or maybe a volume vop? I have tested a volume VOP set up with no luck. Also I find my shader in redshift gives me a plastic look with too much sheen and the normal/displacement looks fake but I can't get it looking better. Any suggestions would be greatly appreciated as I feel I've reached the edge of my knowledge on this. As mentioned I am currently using Redshift, however if someone has a Mantra solution that works well I would be happy to look at that too. I have provided a hip file with the dome light HDR and the mesh cache as well for simplicity. Annnnd this is a small section of the actual amount of honeycomb needed, the actual size is probably 10x that section. Thanks in advance for your help!

  4. map uniform pattern on a geometry

    Hi, I have been looking for a way to create a model that has a certain pattern (like tri, quad or hex - whatever being convex or hole). It is something like this in the picture but the pattern should be all universal in size and shape. (in the picture, the upper part goes smaller and the bottom part being squashed) I understand by doing this, it most likely changes the original shape of a model though. Cheers,
  5. Hi all, Im trying to create damage to parts of the car where I have a tube object and when I move it on top of a surface of the car it will crumple according to the falloff of the tube. I am not doing this by simulation as it is super hard (I dont have much experience in simulations yet). I did try the bullet simulation but no luck and takes forever to simulate. I tried using a falloff node with mountain node on it but it does not push the geometry along the surface direction of the tube. I tried using a attribute wrangler copy and pasted somewhere else but not working.... Im trying to do this in realtime where you move the tube around and it will roughly push and have a noise in the tubes direction but no luck. If anyone can give me a hip sample so I can have a look and see how it is all done would be an awesome help since im still new in houdini. Thanks again in advance I am learning heaps from this community with your awesome works.

  7. Growth Systems

    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.
  8. Procedural Rose

    Hi guys. Recently i saw this two video, and i was blown away. Any clue on how to make something similar ?
  9. Welcome, in this tutorial you will learn procedural level generation with powerful procedural tools in Houdini for Unreal Engine 4. Obviously the main objective is to give you the techniques you can apply to other procedural level. From start to finish we create a procedural level generation tool in Houdini 17.5 and deploy the finished asset into Unreal Engine 4 using the powerful Houdini Engine! The Tutorial covers a range of intermediate techniques including an in depth look at For-Each Loops, control of the direction of the Normals, VOP and many others. Possibility to speed up your level creation using Procedural Techniques in Houdini Engine. Offers the possibility to automatically generate multiple variations of the level. Helps you find the perfect design. Develop a consistent visual language.

  10. Inspired by a tool done by Simon Houdini I decided to recreate same tool on my way. Basically is a nested boolean system which iterates over itself. Starting from a basic cylinder there are three ways to add detail. First is a cylinder which is usefull to generate pivots or a central hole. Second is a circular array of boxes or a circular curve and third is a ray node projecting points over the mesh and copy cylinders there ( useful to attach bolts, screws or make small holes). There are a lot of room for improvements, maybe is not the most user friendly tool of the world and I should try to find a clearer ways to manipulate the tool. I had a lot of problems adding handles or guide geometries because I didn't find the way to switch the guide geometry to older iterations and things like this. At the end I kept at it was without guides and handlers. Please take a look and test the tool. Would be nice have your feedback and ideas for improvements. The tool can be downloaded from here: https://drive.google.com/file/d/1rDgRtMYhhllZWNdANppqnBo9NahtlZNV/view?usp=sharing Thanks for testing it. O.
  11. Hi everyone, I have a little confuse about pc open. Normally we create a pc open need a current element "P" to be the query position. and then search the target file by radius. but what if i create pc open in cvex shader builder to work with vex volume procedural in Shop. where is the current P comes from? we still need a "P" to be the query position to do searching. (plz let me know if I'm wrong thx) if I connect pc open query pos to geo vop global parameter "P" then do the rest of part. although it still work but no idea how. and I don't know how to export the parameters to check on the spread sheet.
  12. I started using Houdini about 2 years ago, recently I have felt a desire to not only share but, hopefully to open up a discussion about the explorations undertaken in the work. The first post is therefore a look at how it began. 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. The video and images below are examples of the earliest explorations (and failures) of this theme, first applied to a modelled object, with the video then moving onto a landscape: https://vimeo.com/376861116
  13. Hi all, I've been practicing and experimenting with VEX in Houdini and I challenged myself to see how far I can go with only VEX and VOP. I did successfully manage to create this simple effect without any use of dynamic simulation (DOP). https://vimeo.com/375250070 Basic Summary: A particle system that computes at frame-basis. I can jump from frame 1 to 700 without waiting for simulation. Instead of the traditional age/life computation, this system uses travel speed to compute. Trajectory generated with polar coordinate + Flow Noise on sphere section. The graph mainly consist of VEXs. There's still room to be improved definitely, if anyone is building more upon this, please share it, would love to see it. I think at the end of the day, this kind of system is probably not entirely practical tbh, but it's a great practice and study on coding with VEX. (SHOUTOUT to a best friend of mine who's studying mechanical engineering, helped me to find a way to calculate the spiral length.) HIP file here: FX_Rasengan_v01.hipnc Happy Coding!
  14. Sketch and etch style

    Like everyone else, I use a bunch of tools for my work. But I found myself using Houdini more and more for 2d work, including making a sketch or etch style of pictures like these. I did it using sops, and while I imagine there is at least a million ways to do that in Houdini, it was bloody fast, took just a few nodes, and with plentiful variations.
  15. Hello everybody, I've got some questions for you. I am soon going to start a new project on Houdini and I need a lot of documentation to have a good start. I want to do a procedural apartment with a defined boundary. The number of rooms can be changed as well as their shape and in the end there will be furniture which will stay in a defined room. If you know of any websites, videos, pdf or even hda wich could be related to all of this I will be more than happy to study them. Thanks in advance for your help ^^
  16. Poly Carve SOP

    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.
  17. Houdini to maya

    Hi, Is there any way to export from Houdini procedurally and working in Maya with that model, I heard that procedurally doing this way doesn't give any issues and works fast in Maya while working with large super sets or even smaller one... I wanted to model a super set in Houdini and import in Maya and shade, light it... Please text If you do any exports from Houdini to Maya...

  19. Hi all I am currently working on a feasibility test in order to build up some understanding of procedural modelling, I have a question regarding expressions in Houdini today, I have received great help from artists in the community which I am very grateful for, thus has helped me get this far, the new question I have is, I would like to delete all the lampposts based on the location of a building box I am using to represent a futuristic house, this box will be a model of a house and will have details like windows and doors later on, with this in mind, am I better of using a proxy box over my model which deletes the lamppost inside the box's radius or is this possible with the actual asset itself?, I have attached an image of what I mean including the current expression within the delete node thank you . Kind Regards Ahmet.B
  20. Rope bridge procedural

    Hi, I'm working on the most original project never did in Houdini before of a procedural Rope Bridge. I have to say thanks for all the help I have found in this forum and now I would like to share with you my progress. (In the description of the video you will find the HIP file) https://youtu.be/kILUeVOmAig
  21. Procedural Armour generation

    Hi, This is going to be my next training series. Procedural armour generation in Houdini. There's still a lot of work to be done. I need to detail the torso, the neck and finally build a head gear. But it's coming along fine, so I figured it looks decent enough to share.
  22. Looking for text animations

    Looking for a talented Houdini artist who can do procedural text animations. We have an upcoming project that requires it. The resulting geometry should be dynamic, procedural, however, lightweight as it will be baked out and used on mobile devices. Please include links to any work you have done in this area, as it will help us filter down the candidates. Thanks!
