Set for arched window 2000-2200 mm.
Arched curtains with goblet pleats with a tieback on one side and tulle on the curtain rod. The curtains are framed with a 15 cm border on the inside of the fabric.
The scene features a simplified model of an arched window in the wall and a simplified model of the cornice to display the mounting.
The curtain set is grouped for convenience. In the export file, all objects are ungrouped.
The colors of the model can be easily changed in the material settings.

For Corona render, it is recommended to use version 1.5 or higher, as the glossiness of the materials is set with PBR in mind.

If you are working in V-Ray version lower than 3.1, please note that the materials in the BRDF section are set to Microfaset GTR (GGX); if your version is older, the BRDF field will be empty. Choose Blinn, Phong, or Ward – whichever is preferable for you.
