Quads only. The model is made under any bed, consists of a set of elements, but is assembled into one object, the normal map for small dents was made independently by the texture of the fabric from the site masterfabrics. Embroidery is made by individual objects, not by texture.

Dimensions under the mattress: 2000x1500, polygon 275 thousand.

Well, traditionally for my models, all objects have correct names in English, there are materials and multi-materials, which are also renamed, textures are also renamed. All the textures painted by myself.

[!] IMPORTANT. Materials for rendering V-Ray, if the automatic conversion of materials for Corona Render passes with problems, your scene hangs or is destroyed, I cannot bear responsibility for this. Open and convert the model in a separate scene.

Who works in the V-Ray version is lower than 3.1. Be careful, in the materials in the BRDF section there is a Microfaset GTR (GGX), if your version is older than 3.1, the BRDF field will be empty. Choose Blinn, Phong or Ward - which is preferable to you.
