GLB Animations

[crazyramirez]

Hi guys!

Thanks for the great contribution, the animations are impeccable.
I usually work a lot of projects in BabylonJS and the file standard it uses is GLB.

I have used a mini App developed in NodeJS to batch convert from FBX to GLB and optimize the animations:

I have also uploaded to Github an example combining multiple animations in a ReadyPlayerMe Character:

I hope you enjoy it.

Thanks again for your work.

Thanks for the feedback, looking great!

We provided them as FBX first to work in Unity & Unreal, and looking into providing GLB-formatted variants as well, which is easier to work with across the web.

Having GLB-formatted variants would be excellent. Until then, tools like those provided by @crazyramirez will have to fill the gap for the glTF-based ecosystems (three.js, BabylonJS, etcetera).

Anyway... thanks for the fantastic contribution.

Adding my vote to a request for GLB files so we can use these excellent assets in even more places.

Mixamo's FBX animations can be used, as-is, with three.js/R3F/drei. But, these animations, when attempting to load them, fail with the following error: Could not load ./animations/backflip.fbx: THREE.FBXLoader: Cannot find the version number for the file given.

Adding GLB versions would be nice, but along with Unreal and Unity, the Movie Maker 3D iOS and macOS apps version 11.0 now support importing FBX animations: https://moviemaker3d.com/avatar-character-body-animations

I've created a fork with GLB versions. Do you have any guidelines to follow for creating a PR (if it's of interest)?

I encountered an error when converting Mixamo's FBX to GLB using Blender 4.0. The error message is as follows. Have you encountered it before?
