  1. Hi, I'm looking for a way to fine-tune exactly what visible OBJ nodes appear in a certain camera. I'm working on a Wrap-like tool similar to what Pixar show here: In terms of having the two camera views side by side, they have two separate obj networks for the source and destination meshes. I would like to contain the process in one network. If I have a simple OBJ network like so : And two cameras pointing to it, is there a way for Camera_A to only show sphere1 in the viewport, and hide box1, despite the fact that both are marked visible? I don't believe it's an option to collect the specific obj nodes together in a Geometry node via obj merges or similar, and just point the camera to that, since the OBJ transforms need to be directly interactible from the camera. Thanks for your help
  2. Hello there, I use a lot of python tools to speed up my workflow. But lately for some reason my Houdini shelf got messed up and a few turned into undefined? Is there any way to fix this? when I left click it said "Menu item filter expression should return an integer" Thank you for your time
  3. Hi all, I'm taking the plunge into Houdini after witnessing the nondestructive iterative power of procedural modeling. One HDA that inspired me was a NPC generator tool that took pre made art assets (shoulder armor, shoes, hats, etc.) and generated NPC's using those assets. I'm looking for help finding the artist + reel that showcased this inspirational tool. The art style was reminiscent of 'The Long Dark' art direction. The models were stylized & hand painterly. I've attached a poor mockup of the tool. I'd love to be able to find this showcase reel again. (The reel also contained a Forest generator tool using spline curves) I've gone back into my search history and googled for hours trying to find this showcase reel. This is my last effort in hoping to find this artist. Cheers
  4. Volumetric Temporal Deflicker 2.1 to Houdini 12.1 to 18.x Deflicker VDB/Fluids by analyzing areas of voxels, creating temporal volume gradients and use this info to interpolate those areas based on temporal volume falloff. It is very good at deflicker slow-motion fluids. Very easy 1 node solution to your flickering fluids or VDBs/volumes in general.

  5. Roots and Veins HDA

    Hi guys, I've created an asset which helps you to create a Roots and Veins systems. Based on a Find Shortest Path SOP, this tool however has a procedural VEX-coded implementation and allows you to create stunning systems just in a couple of clicks. It does geo preparations, clean-up and post-effects, and of course it's very customizable. Feel free to ask me questions. Hope you like it! Some previews are rendered in Redshift (render nodes are not included in the asset) Learn more, watch the video example and get the asset here: https://gum.co/kFSub
  6. I've been learning a lot of vex over the past couple of months and this is my first real practical use trying to make a procedural tool. Let me know what you think! Next iteration is to add more curved lines using trigonometry instead of smooth. https://youtu.be/UsDpGrcrLhE
  7. Modeler 2020

    Product link: https://gum.co/KYCgR What's new: 1. The Modeler core has been completely rewritten. Performance, stability and UX are improved. 2. A hotkey system has been created. Hotkeys are now configured in a separate editor (Hotkeys shelf tool). The editor allows you to quickly configure keyboard and mouse shortcuts. Unlike other modeling programs, you can now associate any tool with any combination of keys or mouse actions. In a similar way, the mouse and keyboard are configured in Nevercenter Silo, but unlike Silo, there are no restrictions here. That is, you can assign absolutely any tool to the mouse. On the other hand, mouse tools such as interactive selection can also be assigned to keyboard shortcuts. Also, unlike the standard Houdini behavior in Modeler, you can use the additional two mouse keys X1 and X2 (Ctrl+X1, Shift+Ctrl+X2 etc). The Hotkeys editor has two default mouse layouts: 1. Standard - that works just like DM and the previous Modeler version - LMB to select items and MMB to drag them 2. Pro - which allows us to select geometry components with RMB and drag with LMB. MMB used to select invisible items too. 3. The interactive state system (add-on for Python States) has been rewritten from scratch. Many tools have become more interactive and have the ability to customize the node in the viewport. In addition, you can quickly create custom interactive python tools for your own HDAs. The mouse wheel now works more universally. In many nodes, the wheel allows you to change the Uniform Scale parameter. List of nodes that now use state tools: Soft Boolean, Insert Mesh, QPrimitive, Array, Hose, Bevel, Extrude, Bridge, Set Flow, Smooth Points, Thickness, View Deform. 4. Retopology tools (Topo category) have been redesigned. TopoDraw tool (Alt+A) allows you to quickly draw poly patches on the reference geometry. It has an ability to snap to existing geometry. Topo mode (Alt+T) now packs the reference model. This speeds up the entire process of retopology with millions of faces. The Push tool now works in the Topo mode, which allows you to get the desired result even faster. In addition, the Push tool has improved performance and stability. 5. The Insert Mesh SOP was redone from scratch. It has interactive tuning, better performance, and more accurate results thanks to improved normals. 6. The Deform menu was merged with the Align menu and renamed to Transform Menu (Z). 7. The Relax tool renamed to Smooth. The tool is completely redesigned and takes advantage of Python States. Using the Smooth tool, you can smooth points or polygons in a standard way. On the other hand, the edges are smoothed as separate curves. Combined with interactive enhancements, the tool allows you to quickly fix messy areas. 8. Tools that create modeling nodes were removed from the Modeler shelf. Only general tools are now on the shelf. Direct modeling tools are now called from the Modeler mode. Added shelf tools: Delete Node, Merge Nodes, Stash History, Pack History, Clean History и Delete Attribs 9. Added a new tool Repeat Node Parms that allows you to apply settings from previously created nodes of the current tree 10. ToolsPanel (spacebar) renamed to Launcher. Launcher tools have been re-sorted and have a new Mouse section for interactive tools like selection or dragging 11. For Bevel, Bridge, Extrude and Smooth tools separate nodes were created 12. Bevel, Extrude, Inset, Smooth, Thickness hotkeys can work as sticky keys. That is, the call of a hotkey, for example, of the Extrude tool, leads to an instant change of the extrusion value before releasing the key. 13. Added Inset tool that uses Extrude SOP. In contrast to the Extrude tool, the first time you start Inset, you can change the inset with LMB. 14. The Lattice tool removed. It is now replaced by improved View 4 and View 9 (View Deform) from the Transform menu (Z) 15. Tools for a quick preview of the subdivided geometry were created: Preview Subdivide (Alt+1) и Preview Subdivide Wire (Alt+2). Standard viewport subdivision and instance subdivision (Symmetrize Tool) ar assigned to Alt+3 и Alt+4 respectivelly. 16. Select By Normals mode (6) allows you to select components based on normals 17. Local transformation tools have been added to the Transform menu: Local Move, Local Rotate и Local Scale 18. An Extend (Y) tool. This add-on to the Extrude tool allows you to quickly extrude edges and polygons using handles. 19. The Bridge Connected tool returned from the DM package 20. Slice, Clip and Mirror tools have the ability to set the initial origin based on points selection center 21. On the next call, the Delete tool changes the node so that it deletes unselected geometry. 22. The KitBash tool now offers to automatically create a KitBash panel if it is not created 23. Shift+Double Click can now replace the geometry of the current Insert Mesh SOP with the geometry from the KitBash panel 24. Combine and Boolean now offer to select nodes at the object level if the tool was launched inside the SOP container 25. Set Flow creates more accurate geometry in unusual situations. 26. Added a Point Weld tool (Alt+W) for interactive point stitching 27. The Soft Boolean SOP can be configured interactively. It also has a slightly improved performance. 28. Collapse History (Left) renamed to Pack History 29. Many tools are assigned to new hotkeys. The ToggleCompass tool is now called with the Backspace key. 30. The Edit Mesh shelf tool now renamed to Modeler 31. Modeler now moved to the package Houdini system instead of using houdini.env
  8. Hi everyone! I'm starting to get into Python 2.7 for Houdini Indie (17.5) before jumping into Houdini 18 with Python 3, and I've been working in a flipbook tool until now everything is being okay but now I've found that I can't recover the camera settings/flipbook settings after generating the MPlay to maintain the user settings after applying the script. I've been trying to use the 'hou.GeometryViewportCamera.stash()' to create a copy of the settings but I'm not sure how to use it and where should I recover these settings. Also when I try to use it I get this error: 'TypeError: unbound method setDefaultCamera() must be called with GeometryViewport instance as first argument (got nothing instead)' I've created a simplified version of the script that I'll be attaching down below: If someone has any advice or idea of how would be the good approaching intro this, I'll bee really thankful. Thanks in advance to everyone.
  9. Hey guys, so I'm building a procedural erode / rock tool. Here are my results so far, the tool generates an infinite number of variations on these. I intend to add more surface detail like cracks and more small geometry details, breaking up the edges more, tweaking the nodes and playing around with it. I'm very happy with the results so far. Also I'd like to know if people are interested in this, it feels nice working on this knowing that it will be useful for people. All the best, Wout
  10. Hi, thought I'd share this in this section too: I wrote an article for the german “Digital Production” magazine about my free LYNX VFX toolset. For the article I made a couple of renderings using the LYNX fabric tools. Luckily it even made the cover Here are my personal favorites, the rest of the images can be found on Artstation. You can also find the complete scene on GitHub under the Demo Files. So now anyone can design an ugly Christmas Sweater;) Looking forward to seeing what you guys come up with, enjoy!

  11. Hi, there. I'm releasing an "early version" of a tool I've been working on. The Wormhole Content Browser is a custom UI for Houdini that enables quick browsing, previewing, and importing of content into Houdini. Some existing features: File browser within a pane tab for easy integration with your desktop. Access browser through parameter context menu to set parameter to a selected file. Easily generate geometry previews using the viewport or mantra. Thumbnails are cached to disk for quick access, especially for previously loaded large images. Import files into SOPs, COPs, or CHOPs. Plus more! Note: This tool is in development, but the functionality currently provided is complete. I am offering this version for free to get people to bang on it a bit. I will continue to fix bugs and make limited improvements to this version. I am planning on adding more features like improving workflow interactions with Houdini, and tools to search through content in a future version that may not be free. Here's a link to the gumroad project page: Wormhole Content Browser Peter.
  12. Hello everyone, I have a setup where I need to cache different bgeos along the way. For this I set up various file cache nodes (collider volume -> flip sim -> flip vdbs -> whitewatersource -> whitewatersim). I'm wondering if there is any way to run this multiple file cache nodes in an orderly fashion? Cheers, Diogo

  16. detecting keyframes with pyton

    Hi Guys I have a very specific request from an animator working in houdini. He wants to have all his animation curves on the objects being animated, he doesn't want to be worrying on parenting or constraints. Right now I have a working tool which it is looking at the values of a source object and keying them to the same parameters on a target object. No problem. But if I wanted to minimize the amount of key frames being created, how would I do that? I can't seem to find a python function for "if key frame present, then..." So my question is, is there a way in Python to detect key frames and execute a function only when one is detected? Any help would be appreciated.
  17. 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!
  18. Get point near the mouse cursor

    Hi. I want to find closest point to mouse pointer. It's not a problem when the mouse pointer intersects with a surface. But how to get the point if it is outside the surface? I have the pointer origin and direction https://s9.postimg.org/a8y8r58i7/image.png

  21. FRC tool for concrete fractures

    Hello everyone! This is the first demo of a new tool I've been working on in Houdini. The idea is to simplify the process of adding steel reinforcement in concrete fractures, specifically FRC (fiber reinforced concrete) My aim is to produce a single node that takes your simmed geometry and adds these steel fibers along the fractured surfaces. Here are some examples of my tool so far: password = vfx Current controls: - max fiber length - randomize fiber length - max angle (before fiber breaks from the adjacent piece) Things I plan to add: - randomize max angle - fragments of concrete stuck to fibers (as seen in example video below) - fiber straightness (how straight/crooked the fibers are) If you have any cool ideas or suggestions, or feedback on my work so far, let me know! (The idea was inspired by the following breakdown video at 2:39)
