Earns its place for baking cloth and physics simulation onto bones so the result can leave Blender for a game engine, with support spanning Blender 3.0 to 3.6 under the GPL license.
Bake Simulation To Bone is a Blender addon from Animation Store for turning a model's simulation into baked bone animation. You rig a model that already has a simulation in just a few clicks, then bake that simulation to the bone and export it to any game engine.
The addon handles cloth simulation and physics rigging, and the developer notes it produces more natural results than doing the same work by hand. It aims to save time, money and effort while staying easy to use.
Bake Simulation To Bone runs on Blender 3.0 through 3.6 and is distributed under the GPL license. Documentation is included, and a demo video is available. An updated version for Blender 4 with additional features is offered separately on the developer's page.
Bake Simulation To Bone is best for blender users who need to convert cloth or physics simulations into baked bone animation for export to a game engine.
Bake Simulation To Bone is completely free to download and use.
Bake Simulation To Bone supports Blender versions 3.0 through 3.6, so 3.6 is covered along with 3.5, 3.4, 3.3, 3.2, 3.1 and 3.0. The developer's page also mentions an updated version for Blender 4 with additional features, hosted separately. If you are running one of the listed 3.x releases, this addon is built to work with it. For anything on Blender 4, check the developer's page to confirm which build you need before installing.
Bake Simulation To Bone is built to bake a model's simulation onto its bones and then export the result to any game engine. The workflow starts by rigging a model that has a simulation, done in a few clicks, after which the simulation is baked to the bone for export. The developer describes this as producing more natural results than doing the same process by hand. A demo video and documentation are available if you want to review the steps before setting it up.
Bake Simulation To Bone is distributed under the GPL license, the same license Blender itself uses. That means you can use it within Blender under the terms GPL sets out. Beyond the license type, specific redistribution or usage conditions are best confirmed on the developer's page, since licensing details can change over time. If your work involves commercial game projects, reviewing the current terms directly with the developer is the safest way to be sure of your obligations.
Bake Simulation To Bone is listed as free in this catalog. Licensing and pricing can differ on the developer's own page, so check there for the current terms before you download. The addon ships under the GPL license and includes documentation to help you get started. If you want a preview of the rigging and baking process, a demo video is available as well. Confirming the latest details directly with the developer is always the safest move.
