Procedural Fluid Simulators

by 3DSinghVFX in Modifier Setups


"Simulate the fluid on any surface with full control"
Introducing full procedural fluid simulators powered by Simulation Nodes and Geometry Nodes. These versatile tools simulate fluid on any grid, curve-grid, or mesh surface, whether open or closed, with support for various mesh topologies like triangles and quads. Enjoy complete control through the field-based workflow of geometry nodes, featuring six force nodes to shape the fluid's behavior. The built-in particle advector lets you create mesmerizing particle effects that flow naturally with the fluid. Perfect for motion graphics and VFX, this simulator empowers artists to craft breathtaking visuals with ease.

Bake

The Blender 3.6, 4.0, 4.1, 4.2, and 4.3 have the baking feature for the Simulation Nodes of the Geometry Nodes. To bake: Select the Object having the simulation nodes -> Physics Tab -> Simulation Nodes (Bottom) -> Press Bake. It will bake and store the cache next to the project file.


Free updates forever

New v2.2 for Blender 4.0, 4.1, 4.2, and 4.3


Project Files

You'll get five project files: A Boat Trail, Face Motion Graphics, Chocolate, Mixing Colors, and Planet.

About

These are node-setups made with simulation nodes of the geometry nodes for Blender 3.6, 4.0, 4.1, 4.2, and 4.3. So, basic knowledge of geometry nodes is needed to use this tool.


License

You can use this tool in any of your projects (non-commercial or commercial).

You may not redistribute the geometry node group itself, for free or commercially.


Happy Noding... :)
