On the imported GLB model, all the meshes inside of it has the same .matrixWorld values. I want to get world position of some of them, how should I do it then?

You can compute the AABB around your object and then use its center point. Something like: const aabb = new THREE.Box3().setFromObject( object ); const center = aabb.getCenter( new THREE.Vector3() );

Hi Oliver. I’ve tried it, still no result [Screenshot from 2022-03-10 16-37-46]

@Mugen87 Hi I guess that you’re aware of this. Could you please help me with this?

Try it with: const worldPosition = new THREE.Vector3(); obj.getWorldPosition( worldPosition ); console.log( worldPosition ); If that does not work, please share an editable live example that demonstrates the issue.

Thanks for your response. here’s the example and here’s the .glb file that I’m testing P.S. You have to upload .glb manually

The objects in your scene have initial position, rotation and scale values since the geometries are shifted from the origin. You see the exact same result when importing the glTF asset into Blender.

So how I can get the position of a specific mesh (lets say position of the wall ) from the center of scene ( global 0,0,0 )?

Why all meshes has the same .matrixWorld values?
