Texture size: 4096 x 4096 px
Actual size: 3000 x 3000 mm

The material of the rubber coating has advanced functionality, you can:
Set any color to the coating
Set any different colors by ID
To paint a part of the inclusions in any two colors through two masks
Create markup using Corona Distance and set it any color
Adjust brightness randomization through a mask

The textures are seamless, the tiling is not noticeable even on large areas. All textures, maps and materials have logical names in English. Texture paths are removed. The Displacement slot is off - if necessary, turn it on, not forgetting to set 0.0 for the Normal slot. All my materials (of the same type) are unified with each other: you can replace or supplement one material with another, being sure that the color and texture will match exactly. You can find other materials for the exterior in my profile:

If you have any difficulties, write me a private message, I will be glad to help you!

ATTENTION!

The .max file has a simple Plane with a material applied to it.

For Corona Render, it is recommended to install version not lower than 1.5, since the Glossiness of materials is configured taking into account PBR.

Creative success!
