HairFlow stands out in the superhive library as a Blender 5 ready addon built directly on Blender's simulation node system, animating individual strands on any curves object. Version 1.2 sharpens collision precision and adds hair interpolation for smaller baking files.
HairFlow, from VICUBE Animation, is an addon that animates Blender's new hair system. It works with any curves object, whether the hairs are generated only through modifiers or are finished hair without any Geometry Nodes, and it can be used for any character or animal, hair or fur.
The simulation runs on Blender's new simulation node system, animating every single hair strand while respecting the original shape of the hair. Physics settings are controlled directly in the modifier: wind effects with independent strength and turbulence, adjustable gravity, and radial force and frizz for effects like electric shocks and goosebumps. You can apply two different physics settings to different hair parts, select collision objects for the main part and an additional independent object, and attach up to two objects to specific points on the hair so they move and rotate with it.
Proxy hair can be activated with one click for faster feedback, and hair interpolation reduces calculation time and baking file size. HairFlow is Blender 5 ready, supports Surface Deformation Nodes, and bakes natively under the Physics Properties tab.
Hairflow 1.2 - Simulate Blender's New Hair System is best for blender artists animating hair or fur on characters and animals with Blender's new curves-based hair system.
Hairflow 1.2 - Simulate Blender's New Hair System is completely free to download and use.
HairFlow is listed as Blender 5 ready and is built on Blender's new simulation node system. It animates Blender's new hair system and works with any curves object, whether the hairs are generated only through modifiers or are finished hair with no Geometry Nodes. Version 1.2 also fully supports Blender's Surface Deformation Nodes and most third-party geometry node-based deformation modifiers, provided the simulation modifier comes last in the stack so it can calculate the deformations those modifiers produce.
HairFlow can animate every curves object, whether it is hair or fur, so it can be used on characters and animals alike. The developer references a test scene from Blender Studio's Cosmos Laundromat demo, where particle systems were converted to hair curves and then animated with HairFlow, along with a simulated fur example on the Fuzzy character. With version 1.2 it also fully supports Blender's Surface Deformation Nodes and most third-party geometry node-based deformation modifiers.
HairFlow bakes the simulation natively under the Physics Properties tab. Simulation data can take up several gigabytes per shot and increases RAM usage accordingly, because Blender does not currently support compressed baking files for geometry-nodes-based simulations. Version 1.2 adds the ability to use only a part of the hairs for the calculation and interpolate the rest, which produces much smaller baking files. You can also activate proxy hair with one click for faster inspection while working.
HairFlow lets you attach up to two objects to specific points on the simulated hair, and those objects move and rotate along with it. This makes it possible to attach items such as hair ties so they follow the hair dynamically. For collisions, you can select a collision object for the head or main part plus an additional independent object, and version 1.2 makes the collision much more precise, allowing longer hair and better object interactions.
HairFlow is listed as free here. For current licensing terms and any conditions of use, check the developer's page. Documentation is included with the addon, and a demo video is available. HairFlow runs on Blender's new simulation node system, is listed as Blender 5 ready, and works with any curves object for both hair and fur, controlling physics settings such as wind, gravity, and collision directly in the modifier.
