Earns its place in the Superhive library as a narrowly focused tool for baking hair physics to a chosen frame, developed from a real thatch-roof use case.
Hair Dynamics Freeze is a Blender add-on built around a single task: baking the shape of hair physics to a specific frame. It lets you freeze hair dynamics and lock the position of hair particles for a non-animated hair shape, so a static result can be kept without continuing to run a full physics simulation.
The developer, 3D Generalist, created the add-on after needing to bake hair physics to a chosen frame for a case like a thatch roof, which doesn't require a full hair physics simulation. The add-on comes with documentation. An example model showing how to create and freeze thatch roof hair particles is not included and is offered as a separate product on the developer's page.
A demo video is available. The add-on lists compatibility with Blender 4.2, 4.1 and 4.0 and is distributed under the GPL license, making it a focused option for Blender artists who work with hair particles.
Hair Dynamics Freeze is best for blender artists working with hair particles who want to freeze hair dynamics to a fixed frame instead of running a full physics simulation.
Hair Dynamics Freeze is completely free to download and use.
Hair Dynamics Freeze lists compatibility with Blender 4.2, 4.1 and 4.0. If you work across these versions, the add-on is intended to function with each of them. Before installing, it's worth confirming your exact Blender build against the version details on the developer's page, since compatibility can shift with newer releases. The add-on is documented, so the included documentation is the best reference for setup and any version-specific notes on freezing hair dynamics.
Hair Dynamics Freeze is listed as free in this catalog. Licensing and availability 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. For details on what that license permits, refer to the developer's page and the documentation that ships with the add-on, which cover licensing and usage specifics directly.
Hair Dynamics Freeze does not include the image model shown alongside it. That model serves as an example for creating and freezing thatch roof hair particles, and it is a separate product available for download from the developer's page. The add-on itself provides the tool for baking and freezing hair physics; the example model is optional and must be obtained separately if you want to follow along with that specific thatch roof case.
