Including living room, dining room, kitchen, and the furniture on the picture, as well as lighting, materials, textures, all models can be moved or saved separatelyThis 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.
ENJOY IT!
