Honami: A Custom Animation System built to replace Unity Animator.

Honami is an open source animation system for Unity that replaces Mecanim with its own graph editor, timeline, rigging system, and runtime.
Every project reaches a point where the built-in tools stop fitting its needs. For the team behind Daisen, that happened while working on first-person weapons, enemy animation blending, and custom skeletons.

As development continued, the team started running into limitations with Unity's Animator. Layer blending lacked per-bone control, and animation events were stored inside animation clips, among other problems.

So they decided to build their own animation system.
The project started as a replacement for first-person weapon animations. Over time it grew into Honami, an animation system that can still coexist with Unity's built-in Animator inside the same project.
Honami comes with its own node-based editor.

States, Blend Trees and Sequencers all become part of the same graph. The system also includes nodes such as Repeaters and Random Animations, making larger animation graphs easier to manage.
The custom Timeline stores animation events inside the controller instead of the animation clips, so imported animations stay untouched. It also lets you preview animation states and test events without entering Play Mode.

Blend Trees also have their own editor, which previews the blended animation so you can see the result while editing.
Another part of the project is Honami Avatar.

The developers told me it works from the skeleton hierarchy instead of Unity's Humanoid or Generic rigs. That allows the same system to work with humanoid characters, creatures, vehicles, or bosses.
The project includes its own rigging system with constraints such as: LookAt, Pose Constraints, Pivot Fixer, Pseudo-Physics, and Bone Replacement.

Honami runs on Unity Jobs and Burst, generates zero GC allocations during runtime, and lets you lower animation update rates for distant characters.

Today, it is available as a free open beta under the MIT license and is already being used in the team's own FPS, Daisen.
