  1. I have a scene where I am dropping a bottle into a flip tank all at small scale. The issue im having is that I am getting a quite a large space/void between the bottle and the liquid. Im trying to reduce this and make the liquid hug the bottle more in the beginning and not blow outwards and make this gap. The setup is an RDB of the bottle falling using gravity from around 10cm into the tank, both the RDB and Flip have been slowed down to 0.025 in time scale. I tried a number of things like lowering the velocity scale, upping the subframes from 10 to 30 in the RDB and upping the subframes in the DOP network to 4/5, and changing the surface tension and viscosity, but it still happens. There is no problem with the collision guide and I dont have any sort of surface offset on that either, it matches the bottle perfectly. You can see in the attached screen grabs that the bottle has barely entered the fluid surface but has created a large void underneath it blowing out the liquid. This is the sort of splash im aiming for: https://www.youtube.com/watch?v=npAuLi1y5AA Dramatic but close and not blowing out internally too much. I know my bottle is a different shape to that reference but my sim seems way off and I cant seem to figure out how to lessen that gap. Any suggestions I would be very welcome as nothing I seem to try is making the gap any smaller. Thanks!
  2. Hi everyone, i got a question and can't figure a way out. Imagine a bottle, and a mesh that perfectly fits into that bottle. I want to convert the mesh into a flip fluid and when i turn on gravity i want it to be as big as before. So my bottle is filled. The reason why i want that, is that I have a drop coming from above and falling into that bottle. When it collides with the fluid inside the bottle, I want a little splash and then the sim is done. How can i get a filled bottle that stays filled after I turn on the Sim. Maybe someone got the same problem or a solution, but i can't get my head around it! Thanks and Cheers!
  3. Hey everyone! I am in the RnD Process of having a bottle filled with water crash to the floor. I have set up the Bottle with Bullet and constraints. Which works fine. Also the FLIP Fluid without Bullet works fine too obviously. Now if I merge the whole stuff the first few frames mostly work well. But the moment the bottle crashes to the floor the Bullet Sim kinda gets horribly explosive. I tried different flip collision method, yet they do not pick up the very thin bottle geometry. Any ideas on how to make this work properly? Or should I just sim both things one after the other? Assuming the water would not have an massive effect on the behaviour of the Glass? Thanks so much for any help in Advance! Hipnc attached. WaterInBottle_003.hipnc
  4. 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!
  5. water in glass

    Hi,everyone. There is a problem i really haven't pay attention to before. I put some water in a glass, the glass was a static object with vdb colision. The water in glass seems not quiet at all, and the water volume was decrease over time even the particle total number was remain unchanged. Is it be a flipsolver problem? and any way to improved? Thanks! water_in glass.hip
