Почему просвечивается модель *.glb React Three js?

<Canvas camera={{fov: 90,position: [0,0, 4500],far: 0}}>
<Suspense fallback={null}>
<ambientLight intensity={0.5}/>
<directionalLight intensity={1} decay={2} position={[0.7, 3.05, 6.6]} />
<OrbitControls/>
<ThreeDLightningSupport/>
</Suspense>
</Canvas>

export default function ThreeDLightningSupport({props}: any){
const {nodes, materials} = useGLTF('/models/lightning-support/test.glb')

return <group {...props} dispose={null}>

    <mesh geometry={nodes.Upper_004.geometry} material={materials['Material.004']} position={[0, 5000, 0]}/>

</group>

}

useGLTF.preload('/models/lightning-support/test.glb')
