If you modeling 3D scenes in 3ds Max and want to import it in game engine such as Three.js, Unity and Unreal Engine,
we can export it using the Alin glTF Exporter for 3ds Max. Here is the steps of how to export glTF files from 3ds Max.

The exporter will generate an .gltf file and optionally an .bin file.
.gltf file is a json file used to store scene nodes, elements types, buffer views, etc.
.bin file is used to store all binary data for meshes and animations, etc.

glTF file format

A simple gltf file can be defined with the scene structure contains a single node:

{
    "nodes": [
        {
            "name": "singleNode",
            "matrix": [1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1]
        }
    ],
    "scenes": [
        {
            "name": "singleScene",
            "nodes": [0]
        }
    ],
    "scene": 0
}

Lights

glTF use extensions to define lights, the KHR_lights_punctual extension can define three light types: directional, point and spot.
These lights are referenced by nodes and inherit the transform of that node.

"nodes" : [
    {
        "extensions" : {
            "KHR_lights_punctual" : {
                "light" : 0
            }
        }
    }            
],
"extensions": {
    "KHR_lights_punctual" : {
        "lights": [
            {
                "color": [0.5, 0.5, 0.5],
                "type": "directional"
            }
        ]
    }
}
