A set of three Roman curtains of a general style which have a width of 800-1200-1600 mm.
There are only 3 curtains in the archive each curtain has a mechanism beam cargo lace. Each model of curtains with a mechanism is one object with multi-material. To change the color you can use the library of materials but it is for the 2014 version so you can just change the texture the material is the same for all colors.
Each element has a scan a grid of quads (almost) bounding edges are everywhere the model is optimized for smoothing the grid is pretty dense so you can use it without smoothing.

For the whole set: peaks – 310000 polygons – 310000.

On the model there are 6 materials I made them myself there are several textures that I also made on my own specifically for this model. Textures of real fabrics from http://masterfabrics.com/.  The names of the materials are written in English and correspond to the meaning.

There are no materials in the OBJ file only geometry.

Who works in the 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 then the BRDF field will be empty. Choose Blinn Phong or Ward – which is preferable for you.
