  1. Hello! I'm new to Houdini, please help!!! I need a small tornado from the fountain that enveloping the character's arm. I try to do this in a simulation, but I can not get a stable beautiful shape. I've tried to do custom velocity field like that too (https://www.youtube.com/watch?v=z19fxCbe2Eg), but still don't get stabil tornado shape. Also,I noticed that if I make a simulation in real size, then it is even more unstable and not beautiful(maybe I'm doing something wrong). The tornado should react to changing the position of the hand (hand is mooving back and forth). And do not know how to achieve the shape of whilrpool,as at my picture. Please, help! armGeo.obj armFX_experinemtal2.hipnc
  2. Hey everyone. Hope you guys are well. I need some help with a shot I am working on. Basic idea is i need to have bits of strawberry to fall into swirling yoghurt,hit the surface,swirl around and slowly get pulled under the surface. I've got the swirling yoghurt working but when I drop my RBDs into the container they plow right through the flip sim. I've tried tinkering with the Feedback scale,Density and so on but nothing works for me. If anyone of you Wizards can have a look and shed some light on what I am doing wrong it would be greatly appreciated I have a scene attached Swirl_03.hip and my swirl force source geo FOR_OD.rar Thanks again Cheers Dimitri Swirl_03.hip
  3. I want to have a puddle of water/lava that starts to rise up to create a character standing up that i have animated, i have tried doing it in reverse by melting him and playing it backwards but it looks wrong, i want to learn how to do it properly. I am looking for any good tutorials that might help me? Any help would be amazing! Thanks
  4. Hello guys, I'm working on a Bifrost liquid mesh that I imported into Houdini to render it with mantra since Maya couldnt manage my huge alembic file ( +300Gb ). There is no foam yet since it's in the process of meshing but I wanted to know what do you think about the liquid mesh shader ? I used the Ocean material from Houdini with some adjustment. Thank you guys!
  5. 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.

  7. FLIP - Accurate Shape Emmiter

    Hey guys, Let's say I want to emmit a fluid from a star shapped emmiter. As soon as I hit Emit Particle Fluid, from the shelf, the shape is converted to a volume, getting fat. Is there a way to preserve the original shape? Thx, Alvaro
  8. Flip Air Resistance Force

    Hi guys, I having an idea on creating sort of a "split" effect with flip, which the particles will somehow randomly lost some velocity while traveling and drag a trail behind it. with this basic concept, I start with a sphere and turn it into emitter. Then I simply add an initial velocity on X-axis and what I got is a water ball travelling toward X-axis. I was expecting the particles will face some "air resistance" force and start to slow down. But it didn't. I tried with drag field or field force, but somehow I not sure if I didn't get the right setting, the result just not what I expecting. Anyone can give me some suggestion regarding this? Sorry if I asked a stupid question. Still getting into it.
  9. Ocean in a Bottle Sim

    Hey guys, I'm extremely new here, and have just been experimenting with Particle fluids and Ocean FX. I'm now trying to achieve a Wavy Ocean effect inside a bottle (eventually it will have a boat on the water) but i'm lost for how to get the Ocean FX to be contained within the Bottle mesh. Could anyone recommend any resources that could help, or push me in the right direction? I have managed to get a FLIP Fluid form Object in the bottle, but the particles slowly leak from the mesh at two points in the mesh. Any help would be great.. Thanks!
  10. VDB Mesh Jitter

    Hey everybody, I've looked all over odforce but nobody seems to be having this problem. I attached a video to show my problem but the title should be very self explanatory. https://www.dropbox.com/s/npwjl49t3p908pv/meshjitter.mov the mesh seems to be very noisy, jittery, and I was wondering if anybody knows how to solve it. The way I'm building it is VDB from particle fluid > VDb smooth sdf > VDB reshape > convert VDB. I've also tried getting rid of the smooth and reshape with no better results. The particle count is pretty high so that doesnt seem to be a problem.
  11. Hey guys, I'm trying to do a simple fill. I have nothing fancy, just a very simple scene of a box(emitter) emitting fluid inside another box (container). All geometry is closed and very simple. The container fills up and the fluids collides like I would expect, but as soon as the fluid reaches a fill line that is level to the emitter (in Y axis) the fill line stays the same. I was expecting the liquid would keep emitting and fill up the entire container until there is no more space left inside.. but it just emits up to the same level as the source, and will not rise any higher. I tried setting up the simulation and sources using my own setup I'm used to in dops, and then tried it using just the shelf tools for safe measure but the problem is still the same. Has anyone ever experienced this before?
  12. Houdini vs Naiad

    Hi,yes another of those threads:) Im new in Houdini,atracted by Flip solver,wonder if im doing things wrong I feel Houdini slower than Naiad,not to mention its consume far more memory. Even the display of particles its slower in Houdini. I know Houdini its a big 3d app and Naiad its focused on just one thing. But again seeing examples from the mighty Igor i see he keep using naiad and just translate the sim to Houdini for shading etc. Wonder if you guys have the same experience or if im just doing things wrong,i even switch the particles from spheres to points,thats speed up things,but not to the level of Naiad.
  13. I`m ussaly not render at all, Any Tips, Hints , Ideas to help me learn how to create realistic render with mantra would be very helpful ! project file
