FLIP Fluids

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

  • Supported in Blender 2.79 and 2.8 for Windows, MacOS, and Linux operating systems.
  • No subscriptions, all future updates included.
  • Free trial available, no sign up necessary.


What is the FLIP Fluids addon?

The FLIP Fluids addon is a tool that helps you set up, run, and render liquid simulation effects. Our custom built fluid engine is based around the popular FLIP simulation technique that is also found in other professional tools such as Houdini, Phoenix FD, Bifrost, and Mantaflow. The FLIP Fluids engine has been in constant development for over four years with a large focus on tightly integrating the simulator into Blender as an addon. It just feels like a native Blender tool!

With our reputation for delivering high quality software and outstanding customer support, the FLIP Fluids addon is one of the best selling products on the Blender Market.

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. 
High Viscosity Effects
Use the high accuracy viscosity solver to simulate thin silky-smooth liquids, thick fluids that buckle and coil, and anything in between. You will be able to simulate thicker fluid in Blender than you could ever before! 
Surface Tension Effects
Create beautiful small-scale fluid effects with surface tension! Simulate the natural cohesion of surface molecules that cause fluids to form into beads, drip, and add an elastic look to splashes. 
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.


Why choose FLIP Fluids? 

Fluid simulation software can be intimidating, complex, and difficult to work with, but it does not need to be. We believe that usability should come first when designing a simulation tool. A simulator might contain the most advanced technology in the world, but if it is not usable, reliable, and flexible, it will not be a tool that is useful or enjoyable to the artist.

Our goal is to improve on many aspects of the built-in Blender fluid simulator such as usability, stability, customization, and to prevent common problems that we see artists encounter when working with simulation systems. We want to provide you with the tools, learning resources, and workflows to assist you in creating beautiful effects as quickly and as painlessly as possible.

Pause and Resume Baking
Bake simulations on your own schedule! Our smart caching system allows you to pause and resume simulation baking- even after a Blender crash. Did you notice a mistake halfway through the simulation? No need to restart the simulation from the beginning, you can update your setup and resume baking from an earlier frame. 
Easily Contained Fluid
Containing fluid inside of an object is a common scenario in many fluid effects. With our Obstacle Inverse Workflow, you can simply enable an option to make your object a hollow container to perfectly contain fluid without any leaks! 
Smooth Meshing Against Objects
Our mesh generator can perfectly handle meshing fluid against flat or curved surfaces, an improvement over the severe voxelization of the built-in Elbeem fluid simulator. No more mesh artifacts poking through your wine glass! 
Tutorial Series and Documentation
Learning fluid simulation does not need to be difficult. Get started with FLIP Fluids by following our video learning series. While using the addon, hover over any option for a detailed tooltip. Visit our extensive documentation and wiki for tips, notes, and detailed descriptions of settings and how they can be used. 
Responsive UI and Feedback 
Being able to see feedback on how your simulation is progressing is essential to a good workflow. The simulator is designed to run in the background so that Blender is still completely usable during simulation. You will be able to view new frames as the simulation progresses while setting up materials and lighting for render. Detailed statistics are provided as your simulation runs to help you understand how your set up is performing. 
Beginner Friendly  
Are you new to fluid simulation? We have a beginner friendly mode just for you! The FLIP Fluids addon contains a plethora of settings for customizing your simulation, but this can make the UI intimidating to new users. Enabling Beginner Friendly Mode will hide the more advanced settings so that you can focus on the common settings that are used the most. 
Debugging Tools 
Is your simulation not running as expected? We provide you with helpful built-in tools that you can use to debug your simulation setup. Visualize the simulation grid to better understand how grid detail relates to resolution. Visualize how the simulator is converting your obstacles into solid volumes to diagnose problems related to geometry and insufficient resolution. 
Stable, Reliable, and Built for You 
The FLIP Fluids addon has been tested by thousands of users, including over 250 beta testers to ensure that this complex simulation system is reliable, intuitive, and ready for you to use in your projects. We listen to your feedback and add your suggestions. This addon is built for you!

What the Artists Say

Grant Wilk, Host of Remington Graphics and CGC Weekly

"The FLIP Fluids Blender add-on allows both artists and simulation enthusiasts to do so much more than they could ever imagine within Blender. The work and care put into this add-on is incredible, and has allowed me to expand my knowledge and abilities on multiple levels. A must have for any avid Blender user."

Lawrence Jaeger, 3D & Motion Design Artist

"Having this kind of power inside of Blender is a complete game changer. To be able to stay within the program that I am so comfortable in and create these kind of FX is amazing. If you are wanting to add liquid simulations to your skill set, this addon is a must have!"

Joel Howe, Technical Animator

"A very promising fluid simulation plugin for Blender with a top-notch feature set, including whitewater bubbles and foam. I worked with the beta to get some great visual results from Blender and was very happy with the stable simulation bakes at a range of solver resolutions. Looking forward to integrating FLIP Fluids into my animation production workflow!"
