FLIP Fluids

by RLGUY in Scripts and Addons

Are you frustrated with the current Blender fluid simulator? Are you tired of spending countless hours baking only to find that your simulation still just doesn't look real? Do you love working in Blender but find that you have to use other software when you need a realistic fluid effect?

NOT ANYMORE! There is a solution, and it is FLIP Fluids!

FLIP Fluids

FLIP Fluids is a powerful liquid simulation addon that gives you the ability to create high quality cinematic fluid effects all within Blender!

The core fluid engine, a modern FLIP-based fluid solver, has been under development for over three years with over a year of development focused on tightly integrating the simulator into Blender as an addon.

The FLIP Fluids simulator was created to improve on many aspects of Blender's internal Elbeem fluid simulation system such as speed, performance, accuracy, customizability, and user experience. We use a familiar and intuitive simulation workflow, so if you have experience with the internal fluid simulator or other fluid simulation software, you will be able to get yourself up and running with FLIP Fluids in no time!

Key Features

High Performance
The core fluid engine, written in C++, is designed for running high performance computations and massive physics calculations efficiently. Multithreaded and extensively optimized, this simulator is built for speed.

Whitewater Effects
Create awesome large scale fluid effects with the whitewater simulator. Generate and simulate millions of foam, bubble, and spray particles to give a sense of realism to large bodies of water.
Viscosity Effects
Use the highly accurate viscosity solver to simulate thin silky-smooth liquids, thick fluids that buckle and coil, and anything in between.

Built-in Mesh Generation
The built-in mesher generates highly detailed meshes so that your fluid surface is render-ready immediately after simulation. This mesh generator is memory efficient and able to produce meshes containing millions of triangles without requiring massive amounts of RAM.
Fracture Modifier Support
Create interesting destruction simulations by using the FLIP Fluids addon with the Blender Fracture Modifier branch. The fluid engine is optimized to support fractured objects that may contain hundreds to thousands of individual pieces.

Excellent User Experience
The addon interface was designed with a focus on functionality and usability to create a comfortable workflow. View simulation progress, meshes, and statistics in real-time. Pause and resume simulation baking- even after a Blender crash. Create and manage your own preset settings. Quickly apply materials from the fluid material library.
Stable, Reliable, and Built for You
We ran a closed beta testing phase involving over 250 testers to ensure that this complex simulation system is reliable, intuitive, and ready for you to use in your projects. We gathered your feedback and added your suggestions. This addon is built for you!

If you are planning to purchase the addon for use on OS X or Linux we first highly recommend trying the FLIP Fluids Demo to test if the simulator will work on your system.

FLIP Fluids Demo

Want to test the FLIP Fluids simulator on your machine? You may try the free demo version. This is a very limited version of the addon that will only allow you to run predefined scenes at preset resolutions. The demo will still allow you to playback and render your test case simulation. This version of the addon was used during the beta to test the simulator on testers' machines and to gather simulation results for optimization.

    Bought it during the Linux beta, and it has worked very well most of the time. The white water simulation is amazing, but more importantly, the developer is amazing. Ryan has responded to each of my many inquiries within hours or minutes and has offered excellent suggestions and support. To be honest, it has crashed a few times during the beta but I think its well worth the money!

  • Filipe about 1 month ago

    While Blender fluids was good for making simple and basic simulations, it simply failed to do anything more complicated then filling a box or a cup. Every time I needed to do a fluid sim with it, it was always an up hill battle. Now with Flip Fluids it opens a lot of doors into the realm of fluid simulation, as almost anything that you couldn't do before is now possible. And the ability to pause a bake and continue is simply a must have addition when doing complex simulations, even though the bake times now are much faster.

    If you always wanted a better fluid sim in Blender that could do complex scenes that are truly realistic, then this is the addon for you.

  • Kishan Narine about 2 months ago

    I must say that the internal fluid system has always been a hassle. I've also been experimenting with another sim for a week now. Then, after using Flip Fluids for one day, well, I just love the out of the box feature. It just works. Of course precision simulations with thin walled obstacles requires some tweaking, but that is common across all the sims. It was definitely worth the buy and I can see more applications in the near future that will be awesome for jobs. Well done to the team behind this and looking forward to future features.

  • Daniel Jones about 2 months ago

    This addon is absolutely stunning! The stability, quality, layout, etc. are spot on! Also, the creator follows through with the open source promise of Blender and is definitely contributing to a better CGI future accessible to all. Supporting this addon by purchasing it will help secure the future of good fluid simulation in Blender. Really an impressive piece of work. I just wish I could borrow a computer from 2050 to bake because I want pretty results faster, but that is just the nature of complex fluid dynamics simulations.

  • Rich O'Brien about 2 months ago

    Fast to bake simulations, nicely integrated into Blender and stunning output.

  • Vojtěch Lacina 2 months ago

    As a beta tester and Maya user with some experiences from Houdini flips, I was very surprised, what B3D Flip can do

  • pharm 2 months ago

    So far, I love it. Just learning and trying new things with it. Looking forward to more tutorial videos. Easily worth the $$.

  • nateordie 2 months ago

    Good results fast! Much easier to work with than the build in liquid sim tools. Thank you for making this, well worth the price.

    Although having doubts about this item before purchasing it, after contacting the very nice creator of this product i do not regret my decision ! Great addon and great support !!!

  • BlindBird 2 months ago

    just wow, works fine and really easy to use, high quality fluid in blender, worth the price

  • Gregory Johnson 2 months ago

    Works beautifully in several test scenes I made as of version 1.0.1. Only issue I've had so far is a specific obstacle object not registering properly, allowing fluid to clip through.

  • andrea 3 months ago

    Worked a lot with Phoenix FD for 3ds Max, a ~900$ Plugin... This Blender Addon can create the same Quality Fluid Simulations!

  • Artell 3 months ago

    Glad this addon exists, it really pushes forward the Blender fluid simulations!
    +More flexible, easy to use, polished than the internal fluid simulation
    +More features to fine tweak the simulation
    +No jagged edges, smooth surface on obstacle/fluid contact
    +Material presets
    +Pause/resume the simulation
    -A bit slower than the base fluid sim

  • rixyarbrough 3 months ago

    Fantastic addon, much more powerful and flexible than the regular Blender fluid sim. Personally my favorite thing about it is it's ability to simulate in massive scale, so instead of a cup of water you could make, say, an entire beach surrounded by water. A few little bugs, but overall, its fantastic.

  • guitartom47 3 months ago

    Even as a beta tester this thing blew my mind. Love the white water. Great animation has already been created and I can't wait to see what people accomplish with the release!!
