Thanks to fritx for this answer pasted

Thanks for using the library!

For now, an component supposes that the mesh exists when it is created, like <object3d :obj="mesh"></object3d>.

If you’re using async loaders, your code might look like this:

<template>
  <object3d v-if="mesh" :obj="mesh"></object3d>
</template>

<script>
export default {
  data () {
    return {
      mesh: null // <----
    }
  },
  methods: {
    createBox () {
      objLoader.load(xxx, geometry => {
        let mesh = new THREE.Mesh(geometry, material)
        this.mesh = mesh // <----
      })
    }
  }
}
</script>

In “ExSpaceFighter.js”, I also had a snippet with MTLLoader and OBJLoader:

Hope that helps.

var mtlLoader = new MTLLoader();
mtlLoader.setBaseUrl( 'SpaceFighter03/' )
mtlLoader.setPath( 'SpaceFighter03/' )
mtlLoader.load( 'SpaceFighter03.mtl', ( materials ) => {
  materials.preload();
  var objLoader = new OBJLoader();
  objLoader.setMaterials( materials );
  objLoader.setPath( 'SpaceFighter03/' )
  objLoader.load( 'SpaceFighter03.obj', ( group ) => {
    const body = group.children[0]
    body.material.color.set(0xffffff)
    this.setState({ body })
  })
})

If I’m wrong, please let me know 😉
