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

Wall Panel Japandi:

– illuminated mirror – 1800*1800 mm
– wall panel fabric material with a printed pattern (2 options)
– wooden slats (2 color variations)

Objects are partially attached textures and materials have logical names
Texturing UnwrapUVW

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
