  1. Hi there! this is my new Canary Surge V2, improved workflow for whitewater, foam and shading stuffs.Please watch in HD 720. Vimeo compression kill of the fine details sorry. http://ipsvfx.com/project/canary-surge-v2/
  2. i have a problem with the splash that comes from collision object into the flip fluid ,i created a flat tank and i imported a strawberry obj and make it to Hero RBD with volume collision , bu tas you see the splash is too weak and the feedback of the fluid jumping after the collision is too high, and i got tired trying to solve it to look realistic particle separation : 0.045 = almost 10 mil density of the fluid : 1100 collision feedback scale : 0 collision force scale : 1 viscosity of fluid: 35 surface extrapolation: 0.001 velocity transfer: swirly kernal surface tension: 10 vorticity : on preservation rate: 0.1 use friction and bounce in solver is off Dop SUbsteps : 2 falling strawberries density : 100 solver type = RBD Houdini version : 16.0.621 hip file included + obj strawberry will be thankful if anyone helped me reference splashes: in this video the reference for the jumping fluid after the collision in the youtube video ate the 0:17 just a simple splash close to crown splash Chocolate_sim.rar
  3. Hi friends of houdini. I stay looking this Fx and I love it a lot. Some guy to knows how I can do this: Many thanks for advanced
  4. Hi guys! I am simulating liquid for my job project about christmas. I can't simulate shape of fluid which would satisfy me. I need liquid with viscosity of milk or somethink more viscous. Another thing I want to achieve is specific shape of fluid (which is presented on examples). I tried simulate this with: geometry, which fell down in to the water tank; emitter and wine glass; POP Curve Force. I am aware that could be kinda noobish question but I ask you to help me investigate where I am making mistake.

  6. Hi all: i'm working on a shot which is similar to the effect of the movie Battleship I've been working on it almost 3 weeks .but I can't achieve the effect exactly here is some screenshots of Battleship,could you give me some advice about the splash? thank you all.
  7. Does anyone have experience with getting stuck at splash screen after updating some drivers etc. on your machine? I had Houdini perfectly working earlier but started to play around with my OSVR HDK which obviously requires to install some drivers, actually loads of them. OSVR works but now trying to launch Houdini it just gets stuck at splash screen, Nuke started to do the same thing also. Things I tried already: - Upgrading and downgrading Nvidia drivers - Same for Houdini version - Deleted the prefs for Houdini. I suppose I need to uninstall OSVR drivers and programs one by one from Control Panel, but if anyone has ideas what could be blocking Houdini from starting it would be greatly appreciated!!
  8. Hello guys, I work whitewater for splash. I made a whitewater source particle. I want high velocity pariticle delete. So I made a high velocity group made. However, The pariticle are removed from the group while slower speeds. For example is parabolic movement. But If I want to continue to maintain, including once in the group based on the ID. I try it use sop solver. but point count changes does not work. Is there any way what? Many thanks, Hyungi Jeon.
  9. Hi! I need to get simulation of the ocean, with waves which would have interacted with floating object (splashes, white water, foam). Ocean surface from Ocean evaluate and splashes from FLIP simulation. But there were problems: 1) Fluid reflected at the boundaries 2) Waves in the flip container do not have same shape with the surface of the initial ocean (ocean evaluate). Desired behavior of fluid has only in the boundary layer. Please tell me where I'm wrong. Thanx. ocean_test.hip
  10. Hi I want to do a Tidal wave braking. It has to be a large wave with a LOT of foam and with a deadly curl. I made this rig so far for the surface with cloth. https://vimeo.com/62003308 Do you think it is better to put this surface animation inside an Ocean Tank 12.5 or it is better to do the traditional way of emitting flip fluids towards this surface and work on foam with velocity dependant?
  11. Hello, CONTEXT I have a scene in which a character is painting a floor. The paint is transferred to the floor as points and converted into a VDB and then geometry (to fit the style of the film). Here's a video of the scene I'm busy with: QUESTION It would be nice to get some secondary splashes when the character slams down the brush (and randomly when he paints on the floor). My initial thought was to source the brush geometry, and give it a pop collision detect (for the floor). Then replicate the points with an initial velocity, mesh them and presto. A couple of problems though: 1. I want the particles to emit only now and them (randomly essentially) and at high impact times. 2. I would like to set the directions of velocity to match the animation. 3. With the pop replicate the shape of the splashes wouldn't look ideal The scene and its alembics are a bit large for the post :/ Thanks
  12. Hi guys, Recently started to learn more on Houdini's Fluids and Ocean tools. Any idea what could be causing the white speckles & weird stretching thing? Maybe its not deep enough, just thinking about it. Edit - Its not the foam solver. Test https://vimeo.com/131536792
  13. Hi, folks! My new tutorial is arrived. It's about how to make crown splash like real flow IOWaterBlast. If you have any suggestion accroding to this tut and the techniques, please share! Thanks a lot!
  14. Hi guys, I know it can be done. I am too close to it, but the only problem is I can't figure out how to create the normals directed along with the surface tangent. I have used polyframe sop too. But its giving the cross pattern which is giving vel a circular motion. How can I face the normal towards the surface exactly...
  15. hi all houdini user... i am impressive about this foam tool when i found this link.. i start to archive that fx in houdini...and start to research for these kind foam FX. then i try to make these SOP setup with metaball on ocean grid and i think thats good for start point.. but ends up when I have problem to continued the the foam because the ship is tracking with metaball so, is there any one could help me how these metaball following the shipa and animated ocean grid.. thanks.. i so much appreciate for these one fx..thanks heres's the hip file and FX references.. foam_tool.hipnc
  16. Hi Folks, I am doing a splash sim. when my Flip tank particle separation is 0.2 the sim gives me a beautiful long curve sim going up and then falling down. But when I am making the particle separation .1 or .08 I am loosing that trail. So I decided to mesh the sim with .2 and now my converted polygon is jerking in the animation flipbook. Is it for the low res sim or the influence factor of VDB?
  17. My Recent work : Responsible for All Elements (Ocean, Ship splash and comp except ship modeling) Thanks to Graham Matthew Collier
  18. Hi, I'm working on water splash for my graduated thesis in school. So far, I couldn't make water surface tension, so I just put emitter on top of fish and spreading water. But it doesn't seem having any surface tension and just looks pouring water. This is my work so far. http://vimeo.com/87121114 I would like to get water tension when fish is jumping from under water surface as following reference. Could you guys give me any advice or suggestion to have natural water tension as the references? Thanks
  19. Hey guys! This quick Flip Fluid R&D was aiming to create a fairly realistic Boat Riding simulation in a large scale water. The video contains a breakdown with some information about my system specs and my simulation settings. The end result didn't come out as good as I wanted to, since I wanted to have more particles and higher render settings, but I didn't have a lot of time working on it and my laptop wasn't able to handle more particles in the given time period I had for creating the effect. But all in all it was a good exercise and it was a fun little project. SOFTWARES USED: Houdini FX, Nuke, After Effects CREDITS: Animation, Simulation, Shading, Rendering and Compositing was done by Laszlo L. Ujvari aka. Myself Boat model was downloaded from 3dmodel.domawe.com Music: Zero7 - Waiting Line Thank you for you attention! Hope you enjoy!
