Curtains set

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

Texture resolution 4096x4096

High quality material and textures. Detailed enough for close-up rendering.
For close angles, you can turn on 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 =)
