Curtains set

Curtains are separate. No need to isolate from one mesh.
All materials are separate.

Texture resolution 4096×4096

High quality material and textures. Detailed enough for close-up rendering.
For distant angles you can turn off turbosmus.

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

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

Enjoy using and successful projects =)
