This file does not have any type of protection. You can reuse the scene, the render settings, the lights, the materials, but above all you can learn from the file, moving inside the project, observing how the light was created and handled, how materials are developed, what is the role that every textures play within them, and the values that fill every single option.
Please Note:The Exchange formats (blend, fbx, stl, 3ds, obj, ..etc) may not appear like the rendered images as shown in the model page & it might miss some textures, to get the same result you need to open & render the model in 3DS max using the proper plugin (V-ray/Corona) to get the same result.
