- gypsum wall panels (reference: https://ru.pinterest.com/pin/11962755251692467/)
- "frame" for a soft panel with bedside tables (headboard level - 900 mm from the floor)
- headboard in two versions: with upholstered panel and wood effect
- Solaris sockets and lever switches from Meljac https://www.meljac.com/en/collections/solaris-collection/ 

All objects are attached, have logical names of materials and textures
TurboSmooth open
Holes for sockets are made using corona distance and auxiliary boxes with the parameter object properties->visibility ->0

For Corona render, it is recommended to install a version of at least 1.5, since the glossiness of materials is configured taking into account PBR

Those who work in V-Ray versions lower than 3.1, be careful, in the materials in the BRDF section there is Microfaset GTR ( GGX ), if your version is older than 3.1, then the BRDF field will be empty. Choose Blinn, Phong or Ward - whichever suits you best
