Let's Flow earns its place in the superhive library for its prebaked approach: the assets skip setup and baking and stay editable in flow speed, material and transform, though editing the fluid shape and rebaking are off the table.
Let's Flow is a Blender add-on built around prebaked fluid simulation assets. It's aimed at adding fluid effects to animations, visual effects and motion designs without setting up or baking a simulation yourself.
Once an asset is in your scene, you can scale it up or down, move it, rotate it and animate it, and you can adjust when the fluid simulation starts to play. Flow speed and the fluid material are both changeable, and you can run multiple simulations in the same scene at once. The assets are lightweight. Because they're prebaked, you cannot edit the shape of the fluids or rebake the simulation.
The fluid assets are compatible with the Cycles and Eevee render engines, while the materials are compatible with Cycles only. Extracting the assets requires 7-Zip, a free file archiver; other archivers will not work. Blender doesn't currently support packing these files into the .blend, so the simulations can't be used on a render farm.
Let's Flow - Add Multiple Fluid Simulation In Seconds!!-No Setup, No Baking is best for blender artists adding fluid effects to animations, visual effects and motion designs without setting up or baking simulations.
Let's Flow - Add Multiple Fluid Simulation In Seconds!!-No Setup, No Baking is completely free to download and use.
Let's Flow lists compatibility with Blender versions 4.2 through 5.1, so it targets recent releases of the software. The add-on ships as prebaked fluid simulation assets rather than a live solver, which you drop into your scene and then scale, rotate, move or animate. If you're running a Blender release inside that 4.2 to 5.1 range, the fluid assets are meant to work as described on the developer's page.
Let's Flow provides fluid assets that are compatible with both the Cycles and Eevee render engines, giving you a choice between the two when rendering your scene. The materials, however, are only compatible with Cycles. So while the geometry and motion will appear in Eevee, you'll want Cycles if you need the included fluid materials to render as intended. You can also change the fluid material to suit your project.
Let's Flow requires 7-Zip to extract its fluid assets to your computer, and other file archivers will not work for this. 7-Zip is a free, open-source file archiver, available from 7-zip.org. Make sure it's installed before you try to unpack the assets, since the extraction step depends on it specifically. Once extracted, you can bring the prebaked simulations into Blender and start scaling, moving or animating them.
Let's Flow cannot be used on a render farm. Blender currently doesn't support packing these types of files into the .blend file, which means the fluid assets won't travel with your scene the way packed data would. For that reason, render farm workflows aren't possible with these prebaked simulations. If render farm rendering is essential to your pipeline, that's a limitation worth weighing before you commit to the add-on.
Let's Flow is listed as free in this catalog. Licensing and pricing can change over time, so check the developer's page for the current terms before you download. The add-on is distributed under the GPL license, and it's built as a Blender add-on extension providing prebaked fluid simulation assets that you can scale, rotate, move and animate within your scenes.
