Texture size: 8192 x 8192 px

Character: black, graphite, anthracite, dark gray, dark grey, natural, stone

The textures are seamless, and the tiling is unobtrusive even over large areas. All textures, maps, and materials have logical names in English. Texture paths have been removed. The Displacement slot is disabled—enable it if needed, remembering to set the Normal slot within the Normal map to 0.0. All my materials (of the same type) are standardized: you can replace or complement one material with another, confident that the color and texture will match exactly. You can find other exterior materials in my profile:

ATTENTION!

In .max files there is a simple Plane with material overlaid on it.

If you're using a V-Ray version earlier than 3.1, please note that the BRDF section of the materials is set to Microfaset GTR (GGX). If your version is older than 3.1, the BRDF field will be empty. Select Blinn, Phong, or Ward, depending on your preference. For Corona Render, it's recommended to use version 1.5 or higher, as the glossiness of the materials is configured with PBR in mind.

Creative success!
