The material of the slate shingles is suitable for both roofs and facades.

The textures are seamless, the tiling does not catch the eye even on large areas. All materials, layers, maps, and textures have logical names in English. Texture paths have been deleted. The Displacement slot is turned off – turn it on if necessary, while not forgetting to set the value to 0.0 for the Normal card in the Bump slot. All my materials (of the same type) are unified with each other - you can replace or complement one material with another, being sure that the color and texture exactly match. You can find other roof tiles and materials for the exterior in my profile.:

ATTENTION!

The author does not give his consent to the use of this material in his models uploaded to the drains, including 3ddd / 3dsky.

There is no tile geometry in the archive: you purchase a set of textures and customized materials. In the files .max is a simple Plane, with a material superimposed on it.

For Corona Render, it is recommended to install a version not lower than 1.5, since the Glossiness of the materials is adjusted with PBR in mind. The materials are configured in Corona 4.1, keep this in mind, as some maps or parameters may be missing in older versions.

Creative success!
