Blender to Mixamo to Threejs

fbx-loader
animation

#1

Hello friends. i have a hard question))
I make model in Blender (fbx), then i load this model to mixamo.com and did the animation. Then i save this file on PC (fbx). In my project i load model:

var loader = new THREE.FBXLoader();
loader.load( 'models/new/robot.fbx', addObj)
function addObj(object) {
  object.mixer = new THREE.AnimationMixer( object );
  mixers.push( object.mixer );
  playerRun = object.mixer.clipAction( object.animations[ 0 ] );
  playerRun.play();
  scene.add( object );
}
function anim() {
 var deltaAnim = clockAnim.getDelta();
 if ( mixers.length > 0 ) {
  for ( var i = 0; i < mixers.length; i ++ ) {
    mixers[ i ].update( deltaAnim );
  }
 }
}

Its OK, but this only one animation in 1 object. How to make many animations in one object.

For example this my object width one animation

This object i find in WEB and in this many animations

This object i find in WEB and in this many animation

What object? Was it an FBX file?

In general FBX files only store a single animation. Some programs such as MotionBuilder can export FBX files with multiple animations but Mixamo cannot. As far as I know blender cannot either.

Yes, this is spider.fbx width many animations

which file to use to make multiple animations? such as moving forward, backward, etс…

You can’t do this easily with FBX. You have a couple of options though, which have already been discussed here:

It’s also possible to take multiple FBX files from Mixamo…

  • mesh.fbx
  • animation1.fbx
  • animation2.fbx

… then import them into Blender, apply the animations all to the same mesh, and export as a single glTF file. I’ve described that workflow further here: https://www.donmccurdy.com/2017/11/06/creating-animated-gltf-characters-with-mixamo-and-blender/

Thank you very much!


#7

I do this! i received two files: gltf and bin. And i see animations in gltf-viewer.
But how play this animations in threejs?


#8

See docs for the animation system and THREE.AnimationAction. You’ll probably write something like this:

var model = gltf.scene;
var mixer = new THREE.AnimationMixer( model );
var action = mixer.clipAction( gltf.animations[0] );

// Play one animation
action.play();

// Play all animations
gltf.animations.forEach( function ( clip ) {
	mixer.clipAction( clip ).play();
} );

Yes, it was difficult for me, but I do this! Thanks a lot :+1:
