I want to present to you a texture that I made by hand from a small sample from the manufacturer's website and made it SEAMLESS. The texture is in 3K format and good quality (unfortunately there are no better quality samples). The work was done in Photoshop. To demonstrate the material, I made a render scene in which you can evaluate the property of the material for a glare, for bright lighting, from different angles.

In the scene you will find a tile of formats:
- TILE - 2780 x 1200 mm
- TILES - 2400 x 1200 mm
- TILES - 1200 x 1200 mm
- TILE - 800 x 1600 mm
- TILE - 800 x 800 mm
and a mosaic canvas without texture tiling:
- MOSAICO 36T - 3600 x 1200 mm
- MOSAICO 144T - 3600 x 1200 mm

All objects and materials have unique and correct names. The materials are simplified as much as possible, I converted the Corona Render materials and did NOT check them in the scene for rendering, check the model in a separate scene.

There are no materials in the OBJ and the file, just geometry.

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