The file comes with render setup, useful for furniture shots

Each object and material has been conveniently named (English). All elements are parented to an empty and grouped. To import the model into your scene, use append or link and navigate to the group folder to load it. Use the empty to move and manipulate the object

The rosewood material uses a complex PBR setup, mixing a base texture and a dirt/worn-off one, also with normal, roughness and specular maps.
