R3F add png background on jpg background

hello, I made a background with a jpg file and I want to configure my room by adding png files on top of this background. (similar to this example:3D Room materials displayer with React). I’m waiting for your help.

 <group>
      <mesh>
        <sphereGeometry args={[500, 60, 40]} />
        <meshBasicMaterial map={texture //main background jpg } side={THREE.BackSide} />
      </mesh>
      {/* <mesh>
        <sphereGeometry args={[500, 60, 40]} />
        <meshBasicMaterial map={config // new config image png } side={1} />
      </mesh> */}
      <mesh position={position}>
        <sphereGeometry args={[1.25, 32, 32]} />
        <meshBasicMaterial color="white" />
        <Html center>
          <Popconfirm
            title="Are you sure you want to leave?"
            onConfirm={onClick}
            okText="Yes"
            cancelText="No"
          >
            <a href="#">{name}</a>
          </Popconfirm>
        </Html>
      </mesh>
    </group>

<meshBasicMaterial
map={config}
transparent={true}
side={THREE.BackSide} //solved my problem :slight_smile:
/>
