Reflect the environment image to the object's body or glasses

Hi members!
I have a 3D car that I loaded in my scene.
I also created a background for my scene using CubeTextureLoader().
What should I do to reflect the environment(Cube) image to my car’s body and glasses?
For example, when I load it in, the environment image that is trees, reflected on my car body. Like the below image.

Thanks for your help.

In order to have a material reflect your environment map, you need to set its envMap.
Have a look at MeshStandardMaterial.envMap
The GLTF viewer, that you linked, applies its own envMap by default.
