What do you mean? Is this asset syntax not working with a loader in this repo?

[7dir]

yeah
not working

            <a-assets>
                <a-asset-item id="flower" src="flower/flower.json"></a-asset-item>
            </a-assets>

            <a-entity
                        object-model="#flower"
                        position="0 0.1 -3"
                        rotation="0 0 0"
                        scale="0.5 0.5 0.5"
                        animation-mixer="clip: default;"
            >
            </a-entity>

@7dir If you check this: https://glitch.com/~hickory-sand-liver is working

<a-assets>
        <a-asset-item
          id="golem"
          src="https://netgfx.com/trunk/CORS/golem/scene.gltf"
        ></a-asset-item>
        <a-asset-item id="goblin" src="https://netgfx.com/trunk/CORS/source/scene.gltf"></a-asset-item>
      </a-assets>

then

<a-entity
        id="bot"
        cursor-listener
        scale="0.5 0.5 0.5"
        position="0 0 -6.5"
        rotation="0 0 0"
        animation-mixer="clip: IdlePieces;timeScale: -2.5;clampWhenFinished:true;repetitions:1;"
                
        gltf-model="#golem"
      ></a-entity>
