There are eight materials and six textures inside the pack:

-Black marble with polished / leather (matte) / rocky finish.
-White marble with polished / leather (matte) / rocky finish.
-Concrete floor
-Light material

All textures are totally seamless.

The diffuse texture resolution for the black marble is 3000×3000 pixels and for the white marble 2400×2400 pixels.

All the textures (except the displacement) are square.

There are reflection bump and displacement textures for both the black and the white marble.

VERY IMPORTANT:
Even though the displacement map is active for the rocky stones I recommend deactivating it and instead of the following:
Select the object (s) to which you want to apply the displacement. Go to modify the tab and select the V-ray displacement modifier. In the properties for that modifier copy your desired displacement map in the texture part. Set the max subdivs to 64 and check Keep continuity.
