[Turtleted21]

Hello
it don't work with gltf-model, I must add a empty entity as parent and use this parent to work like this :

<a-entity id="nook2" position="0 0.2 150" class="clickable" look-at="[camera]">
     <a-entity id="nook" gltf-model="#nook" shadow="cast: true; receive: true"  animation-mixer="loop: repeat" class="clickable" onmouseenter="popup_question(this)"></a-entity>
</a-entity>

another solution?

Thanks
