Since there are materials with Displacement in the scene, it is better to use millimeters as units of measurement.
If you use other units of measurement, you will need to adjust the Displacement size in the material settings.
Materials from Displacement:
chalet_rooftile
chalet_wood_siding
chalet_stone
chalet_brick

You may need to adjust the light material value in the settings.
Light material:
chalet_handle_light

The archive contains FBX and OBJ files and libraries of corona and vray scene materials

If you are working in V-Ray version 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, the BRDF field will be empty. Select Blinn, Phong or Ward - whichever is more preferable for you.

For Corona render, it is recommended to install version no lower than 1.5, since the glossiness of materials is configured taking into account PBR.
