  1. Mystique Ocean

    R&D in Mystique type effect - flipping tiles driven by procedural animation. In this case, I used curvature to drive rotation of tiles in copy stamp sop.
  2. 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
  3. Boolean random seed per stamp??

    Hello, I'm trying to create some really basic glass debris (small on screen and limited in poly counts (games)), so instead of using material based debris (too directional) or voronoi fracture (too hexagonal looking), I thought I would use Steven Knipping technique and use booleans. -create one glass panel -add points -attribrandomize the points -copy to points grids for cutting -boolean scatter the glass panel with the cutting grids -copy stamp the panels ...wishing to use stamp to add randomness to attribrandomize. It works great except that I can't get the randomness of my stamp attribute to randomize the seed, so all panel look the same. I'm creating a rnd attribute in the copy stamp SOP with the following expression: rand($NCY) and in the attribrandomize under options tab>Global seed I enter: stamp("../copy6/", "rnd", 0)*12345 If anyone as a minute to take a look or has any suggestion that'll be fantastic!! thanks BooleanStamp.hip
  4. I'm attempting to make a cloudscape time lapse and need to find a way to efficiently create the cloud volumes. My solution so far has been to build the clouds themselves from spherical 'puffs' and to instance those puffs onto points at render time. My issue with this method at the moment is I can't find any way to have control over per-instance variations (beyond transforms, mostly looking for varying density). I have attached a file that shows a basic setup. Cache the frame to your local drive and make sure the instancefile attribute path is set to the cached file location correctly. One solution to my problem could be to cache multiple cloud puffs at different density values, and use different instancefile paths. But this will get heavy quickly as I need hundreds of frames to make up the time lapse animation. I'm hoping to find a method similar to how you would do regular copy stamping, using pt attributes to drive variations in the instanced geo. But obviously copy stamping is too heavy for my purposes. Any ideas/thoughts would be greatly appreciated! clouds_v001.hipnc
  5. CAMP_2016_Behind_The_Scenes_on_626475235.mp4 Very nice piece in my opinion by Raw & Rendered! Inspiring. I believe the technique is related to curl noise and many examples I found in this forum. However, I am particular interested in this setup where the curl noise is actually controlled by guide curves/circles. Also interested in how the spheres are randomly scattered on the curves and flows with the motion. I have attached the actual references for the frames. I am very new to Houdini and love procedural. Have been experimenting with wrangler nodes, sops, vops and etc. It would be great if anyone could share the approach on creating a piece like this. Looking forward to your input.

  6. Hey guys, I would usually do this easily with a Copy Sop (Copy to Points now), just like on Rohan Dalvi's Mograph Series but, since the fragments are not over points, I have no idea on how to do this without a stamp. Here's something very similar from what I need, it's just rotation and scale of the individual pieces: Thx, Alvaro

  8. Modelling a disco ball

    Hi all, I'm trying to model a disco ball via copy stamping some extruded grids onto a sphere (polygon mesh). It's all good until it reaches the points at the poles, at which point the copied geometry begins to overlap due to the points on the sphere being closer together. Also, how would i introduce some random rotation to the rows? at the moment it's quite uniform and if you look at an actual disco ball, there's some slight variation. Any help is much appreciated x
  9. fixed particle id

    hola, i'm copying box and a sphere to particles and using copy stamp in order to randomize their scale. (rand($PT+215)) i'm watching my particles as they travel ,their point numbers are changing. so my expression returns diffrent result at every frame , so overall effect is look jittering. any idea how to fix? h14_jittering_particlescale.hipnc
  10. Hi, I'm trying to create an effect that grows dandelion seeds over the surface over time. I've used a copy stamp to grow the seed from 0 - 1 for the coloured partic.es At the moment the seeds grow from scale (0 - 1) on the frame (0-100). So when the point is birthed at frame 50, the scale will be 50% because it's on frame 50. Does anyone know a way in which the particles start the growth from when they are birthed so it's not as uniform? I've attached my .hip file. Thanks in advance! Growth_Test.hipnc
