  2. Toms "Learning Houdini" Gallery

    "Rumis Field" "Out beyond ideas of wrongdoing and rightdoing there is a field. I'll meet you there." Rumi One of my favourite quotes ever... And an organics version: Both created with a custom solver in Houdini 17.5 & rendered in Redshift for High-Rez printing at 18000x12000 (https://www.artstation.com/thomashelzle/prints). Cheers, Tom

    And of course I did the Entagma Physarium tutorial :-) Awesome stuff, thanks guys! Houdini 17.5 Cheers, Tom

    "She Flow" I really love how this one came out - make sure to view the full size one for the details. Houdini 17.5 & Redshift & Luminar 2018 Cheers, Tom

    A weeping willow created in Blender with "The Grove" to grow almost flat onto an obstacle... then further processed in Houdini 17.5 Rendered in Redshift. Cheers, Tom
  9. Permission issue

    Look for "packages" in the help. It´s cleaner and will solve this bug.
  10. Today
  11. RBD follow animation softly (Soft constraints)

    assemblyRnD_martin_v21_walksim_working.mp4 That's how a first version ended up looking! Just some noise to make it more alive... But it's something to start the buildup from.
  12. Need help with loops and Foreach

    This is gorgeous!!!!
  13. Minimal spanning tree

    A basic way to span a graph that efficiently connects all points using Prim's algorithm. https://en.wikipedia.org/wiki/Prim's_algorithm minimal_graph.hipnc
  14. Hi, I'm very unfamiliar with Houdini. I simply want to bake a displacement texture from a object. So that I can apply the look of the model to others with just a texture. How could I go about this? Thank you.
  15. POPs: pre solve vs post Solve

    Pre-Solve Microsolvers attached to this input will run before the main solve step. For example, a SOP Solver can be used to modfiy the object’s geometry, and POP force nodes can be used to apply forces to specific objects. A good example for pre solve use is the Gas Resize Fluid Dynamics in Pyro Solver, where it resizes the container at each step. Post-Solve Microsolvers attached to this input will run after the main solve step.

    Did you find an answer?
  17. UV cubic map procedurally

    Thanks a lot Konstantin Magnus!
  18. Animated noise on guides or hair

    Answering to myself in case someone is looking to do a similar thing. As it turns out the guides are just polylines and can be modifed as such. I've added a UV Texture SOP on the points with Rows&Columns to get the UV parameter along the polylines and then this vex code on a point wrangle sop: float freq = 30; // Noise Frequency float phase = @Time * ch("phase"); // Noise Phase float amp = 0.01; // Noise Amplitude vector noise = noise(@P * freq + phase); noise = fit01( noise, {-1,-1,-1}, {1,1,1} ) * amp; @P+=noise * v@uv.x; I've inserted these two nodes right after a Groom Fetch SOP because I needed to deform the guides on sop level but you may as well insert them before the GUIDES output inside the Guide Groom Geometry node. Hope this helps someone.
  19. Need help with loops and Foreach

    More cuts where the colour is a lighter value and less cuts where it is darker. Then a local rotation matrix to rotate only blocks above a certain colour value. Final colour scheme slightly different than the one that drives the cuts.
  20. You have to do it manually. Plug the constraints into attribute wrangle and simulated pieces into the second input. Then use this expression: int pt = findattribval(1,"point","name",s@name); if(pt>=0)v@P = point(1,"P",pt);
  21. Houdini 19 Wishlist

    0. Updated code editor. That's the biggest dream. I freaking love coding for Houdini, but that's one of the aspects what still feel like pre-16 version. Maybe the team can integrate Electron framework or something. You don't want people to go and use external editors for anything more then a few lines. 1. COP3 context. Houdini 5.5 gave us COP2. It was in 2002. It's still in 2002. I do believe what Houdini can shine with 2D too, both in procedulal generated images, and even with compositing. But it's not. Most of us just try to find other ways around instead of going there. 2. Physics-based Animation. Solaris gives us a fantastic method of doing layout work based of phisics. It's trully amazing. Why not to impliment the same approach into animation. There is a team what is doing it already, making Cascadeur app (https://youtu.be/nj_Dtj7c0Lc). I'm pretty sure SESI can do even better. It's a chance to get a tiny piece from nearly impossible task of taking Maya's pie. 3. Texture painting. Hear me out, nobody expects Mari/Substance level of painting, it's not for that. But a lot of times it's beneficial to paint something basic and not be dependant on topology. For example: I don't wanna go into painting app just to put a few tiny dots and the cat's face in order for fur to be colored by it later.
  22. Hi all, I have set up a tool that takes an input mesh and performs an operation that writes new vertex color to this mesh. I am looking for a way for the HDA asset inside unreal to take the input mesh and overwrite the vertex colors of that specific instance in the world is this an achievable effect? Thanks all, Dom
  23. Bitmap Voxel 3D Printing

    Thank you! @konstantin magnus @Librarian i just wanted to share this app and extension which i found yesterday and can be useful for you both maybe. Here you go: https://download.slicer.org and https://github.com/SlicerFab/SlicerFab Will post some results asap, cheers! F
  24. I' m trying to understand Anastasia course but I don't know how to modify her foreach in the loop closed_balc On the left Anastasia's version and on the right mine not working Any idea ? Thx hdni_lake_house_opara_chapter1_2.hiplc
  25. Hi all, I am running sims with houdini engine on amazon aws ec2 instances. Using Thinkbox Deadline and Usage Based Licensing. It does work, but there is a ~75% chance, the sim won’t start and throw a Segmentation Fault immediately after a message about OpenCL: 2019-11-15 14:26:17: 0: STDOUT: Rendering frame 1 to 240 2019-11-15 14:26:17: 0: STDOUT: OUT_whitewater at time 0 2019-11-15 14:26:17: 0: STDOUT: Bytes sent: 0 2019-11-15 14:26:17: 0: STDOUT: Bytes received: 0 2019-11-15 14:26:17: 0: STDOUT: Seconds taken: 0 2019-11-15 14:26:17: 0: STDOUT: ALF_PROGRESS 0% 2019-11-15 14:26:18: 0: STDOUT: No OpenCL platform has the specified device type (HOUDINI_OCL_DEVICETYPE): GPU.

So my guess is, it has something to do with the CPU OpenCL driver. The instance used here was c5.18xlarge. Here is some info on the CPUs I found on AWS for the C5 Instance type: I also asked this over at the Thinkbox Forums, but I think it is more of a houdini issue. Thanks!
  26. Its not working...i thing im doing some mistake bcoz im new to redshift. how to use attribute directly as emission..or as a multiplier.....?
  27. error in /physarum-slime-mold

    Thanx Fred
