ozz-animation
By Guillaume Blanc
Engine-agnostic C++ skeletal-animation library with playback/blending and glTF/FBX conversion tools for custom animation runtimes.
Start: Follow the CMake build guide, then use gltf2ozz or fbx2ozz with --file to convert skeletons and clips into .ozz data. Load that data for runtime sampling and blending, and connect the resulting poses to your game.
Limits: This is an animation library, not a complete rendering engine. The FBX toolchain requires Autodesk FBX SDK. MIT licensed; no build or conversion was tested in this review.
