  1. Hi all, I have a rigged character from Maya from which I did a Ragdoll sim and all is good. However now I want to do it as a FEM sim instead, to get some bulging when the character gets hit by an object. How would you go about doing this? While still having constraints on arms, etc. Thank you very much in advance. Cheers, Jonas :-)
  2. Hey peeps, I'm new to houdini and trying to create a fur effect. I'm following the video on the SideFX page, but I ran into a problem that's probably very simple, but problematic for a beginner: when I select limit to bounding box, the box isn't there. Now I don't know if it's just not visible and I need to zoom it on it (though I tried selecting the move tool to see if it would become visible) or if it's just not there. I imported a 3D model from maya if that's an important factor. Thanks in advance!
  3. I have two separate stacks of geo made using copySOP's, i am trying to get them to interact with each other. They do interact with each other but the constrains only effect one model, i can switch them in the merge but its only ever one that holds together, the other falls apart instantly no matter what the glue strength is. Ive put photos below and attached the scene file with the model that needs referencing in. New to Houdini so any help or advise would be greatly appreciated! Thanks PlateSimulationTest001.hipnc plate.obj
  4. Hello! In this Masterclass, at 41:00, the teacher explains that fracture parts of the object can be localy modified using an attribute. So my question is about this : how do you control what part of the object will fracture? is there a way to connect the FEM solver to a voronoi attribute or anything like that? Thank you for your time!
  5. Hello! Do some of you sometimes use Fluid Force node? I want to have my fluid having influence on meshes, and I cannot manage to set the node properly. If you use another method for this, I would be happy to learn it. Thank you! leafNdrop.hip
  6. I Have stacks of plates and bowls that i made with a copy node on one original model of each type of plate or bowl rather than importing each model multiple times. I want each object to be able to fall and smash independently which i am struggling to work out. When i make the stack a RBD Glued Object it either all moves and smashes the exact same way like they are being read as one whole piece rather than individual plates/bowls or they move individually but the glue errors saying "making objects from different solvers mutual affectors" so they cant smash. Sorry if this is a basic question i am new to Houdini, any help would be greatly appreciated!

  8. Check out the new tutorial about creating explosion with pyrofx in Houdini. https://www.cgcircuit.com/course/explosion
  9. Hey Guys, I am pretty new to Houdini so excuse the noob question. I did a pyro sim and saved it for 120 frames as .sim cache. Client asked for extra frames so i came back and simulated extra 100 frames. When I render I get the proper render for the original 120 frames but for the remaining 100 frames I have a frozen frame at F120. In my cache files I can see the size changing so it seems like the sim went all the way, but in the view port I cant see it (It is frozen after frame 120) and in the render it only renders upto 120 and then frozen frames. I tried re simulating the whole sim for the entire 220 frames but it sill gives frozen frames at 120. SO I am a bit confused as to what should be my next steps to trouble shoot this issue. Cheers!
  10. fireballs

    Hey guys, i'm working on a personal project involving fireballs. I could use some help to get flame trails. Right now the flames are going straight backwards corresponding to the velocity of geo which is fast. Any tips or tricks to get those flames look interesting? I have tried negating the velocity before plugging it into fluid source. Tried emitting from particles. Both doesn't work. Thanks!
  11. I have an animated cabinet that i have imported to Houdini from Maya as an FBX. I want to drop cutlery into one of the draws in the cabinet, i have imported the spoon .geo and made the cabinet a static object and the spoon an RBD object. when i drop the spoon onto some parts of the cabinet it lands fine. I want to drop it inside the draw before it opens but when i position it above the draw and play through it doesn't move, it is just frozen in the air. Im guessing its a problem with bounding boxes? Sorry im new to Houdini any help would be greatly appreciated! (Sorry for the bad angle, the draw is closed)

  14. Has anyone tried masking fields in Houdini while using Finite Elements? I am trying to mask the Gravity field in a Finite Element simulation in Houdini. But I cannot get it to work.
  15. effect

    hi, everyone. I'm student in japan. I'm sorry.I use only bad english. btw, I reseached to move RBDobjects by pyro sim. I use POP Advect By Volume. but, it's not going well. Where are I going wrong this way. if you know a different good way. Let me know. Please. test_RBD_moving.hiplc
  16. Hi guys, so I'm doing a scene where berries falling into a bowl but I use a sphere and a simple cup modeled to visualize then I realized when I use rbd object on the sphere and static object on the cup, the sphere doesn't drop into the cup but instead it drop just before the cup. I've been trying to figure out but I have no idea why it turns out like that. Any clue what happened? testyog.avi
  17. Houdini FX artist specializing with hair and curves generations is needed for on-site contractor work in the Silicon Valley / Los Angeles area. Must have the ability to work within a VRay/Maya pipeline and create, rig and control intricate patterns like below: https://vimeo.com/59736707 Please send demo reel and examples to: joelangmuir@gmail.com and I will forward to my manager and recruiting.
  18. I have an object shattering using a voronoi fracture, i'm importing it to Maya as an alembic cache but i have to manually select all of the inside faces of the cracks to texture them differently. Is there a way i can select all inside faces on a voronoi fracture object in Houdini to make things quicker? Thanks
  19. I'm trying to arrange (or add) points on a line so that the distance between them decreases based on a ramp. I have a ramp controlling Cd on the line using: @ptnum/(@numpt -1) I tried using a scatter node and generating the points based on Density Attribute Cd. But this results in some randomness in the decreasing distance. I thought I could use the resample node's distance attribute. but i haven't figured it out. I could one could shed some light here I would appreciate. Thanks B
  20. Hey guys, trying to use the wedge rop to create multiple pyro wedges to then drive particles - i thought my setup was correct and cant find an error myself but all the wedges look identical, provided my file so have a look and would be great if anyone had any ideas Thanks as always Chris Ink_Water_v2_t1_introducewedge.hip
  21. Hi Everyone, I was wondering if there is anyway in Python to run a function only when the left mouse bottom being held down? Thanks,
  22. Is it posable to transfer the @Cd attribute to geometry with the instance sop? With the copy sop you can Use "Template Point Attributes". The instance sop has no such option. The instance object picks up a @psclale attrib but not a @Cd attrib? Thanks
  23. I have inside information that Arenanet is looking to hire a Houdini FX artist soon. This job posting doesn't specifically mention Houdini, but I've been told that they want to get someone with Houdini experience. https://boards.greenhouse.io/arenanet/jobs/585233#.WMGhjPnyvup
  24. Creating a node takes ages. What could be the problem that is making it so slow? It did this after the latest update (updated 15.5.632 to 15.5.674) Please note that we already tried to install versions as far back as 15.0 and until the latest version of 15.5. The problem keeps occurring even without virus scanners and windows defender being turned off. It also doesn't matter if it is installed on a SDD or on a HDD and all the drivers are up to date. Even if all the preferences have been deleted (in the documents directory) it stays the same and it also doesn't matter on which Houdini License server it's running: in Standalone mode or not. I'm running out of ideas to what the problem could be. If you know the solution or have an idea what it could be, let me know! Please ignore the audio in the example video below, it is in a noisy classroom with students discussing different nodes (not related to what you see, you can watch without audio)
  25. I've always been fascinated by procedural set modeling, so I figured I'd try my hand at modeling some tropical marine life in Houdini. I'll be posting my progress here! I have started hashing out a few basic types of coral, anemone, etc. Hoping to eventually get this all into a large scene. Anemone motion test: I apologize, but I cannot currently share hip files of these scenes since they may be used in a contract.
