Problems with ColladaLoader2

Description of the problem

Hello @Mugen87

Now I use the ColladaLoader2 to load my model and play the animations but I get errors and display problems :

• the model does not display correctly, see by yourself. With the ColladaLoadermy model displaying well.

• the updating of the mixer for animations generate this error on the console : can not bind to bones as node does not have a skeleton PropertyBinding {path: ".skeleton.bones[Hips].position", ... For each error corresponding a warning during the loading like : ColladaLoader2.js:2276 THREE.ColladaLoader: Missing data for bone: Hips. However you can see the skeleton on the picture I linked.

The model come from mixamo : https://www.mixamo.com/ , which gives quality models.

Considering this code :

loader.load(source, function(collada) 
{
	const obj = collada.scene;
	const animations = collada.animations;

	obj.traverse(function(child)
	{
		child.castShadow = true;
		child.receiveShadow = true;

                if ( child instanceof THREE.SkinnedMesh ) 
                {
                       this.skeleton = new THREE.SkeletonHelper(child);
                       this.skeleton.material.linewidth = 3;
                       this.skeleton.visible = this.skeletonIsShowed;
                       this.environment.scene.add(this.skeleton);
                }
        }.bind(this));

        this.mixer = new THREE.AnimationMixer(obj);
        this.clip = animations[0];
        this.mixer.clipAction(this.clip).play();

}.bind(this));

Thanks for reading.

I’m not sure if the animation data of this object are valid. As far as i can see, the file only contains two keyframes per bone. Besides, the time values are very strange (0.000000 and 0.033333). So the total length of the parsed animation clip is 0.033333 seconds. Well, it’s no problem to change the duration for playback but still these data seems strange to me. Currently i was not able to playback the animation (ColladaLoader didn’t work either).

BTW: I’ve imported the model in sketchfab and no animations were parsed at all, too.

@SebastienFPRousseau Can you please verify if the animation data of your model are correct?

It’s weird… I suspected something like that. I will try another model. Thanks for the texture correction, waiting for the release. Animations mustn’t be valid.
