Corona version 9
The model uses materials that may not be displayed correctly in very old versions of the engine.

Composition for the Lunar bedroom with soft wall panels
The panel consists of separate easily editable elements
Objects are partially attached textures and materials have logical names
Texturing UnwrapUVW
For close angles to the panel I recommend using TurboSmooth
(the geometry is prepared for smoothing)

For Corona render it is recommended to install a version not lower than 1.5 since the glossiness of materials is configured with PBR in mind.

Who works in a V-Ray version 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 then the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable for you
