GLTF
You can load .glb/.gltf models with the built-in <gltf> component:
<template>
<TroisCanvas>
<gltf src="/your/model.glb"/>
</TroisCanvas>
</template>
A GLTF ends up being added to the scene as a Three.js Group, so you can change all Object3D properties as if the <gltf> were a <group>:
<template>
<TroisCanvas>
<gltf
src="/your/model.glb"
position-z="-10"
scale-y="5"
/>
</TroisCanvas>
</template>
