A simple example of using VRayFur in 3ds max to create a furry carpet.

The VRayFur is grown on a beveled surface, that has no bottom side surface to avoid growing fur at the bottom, and also because it’s unneeded.
The surface is beveled at the edges so that the fur there will grow to the sides,
And a noise modifier is applied to the surface to break its uniformity and give it a more organic shape.
* You could have a bottom surface set the fur not to grow on the bottom polys.
A combination of 3 procedural Noise maps (for each of the RGB channels) is used to create a direction map for the fur threads. the maps are added together using a VRayCompTex map.
The reason the pattern is separated to it’s RGB channels is that it allows more control.
A VRayFur direction map works like a normal map in tangent-space and this means we can’t have the blue channel be less than a value of 0.5 because that would cause the fur to grow down into the surface.
For the fur material, a VRayFastSSS2 is used to achieve a ‘fluffy’ organic look combined with a VRayDirt map to accentuate the shadows between the fur threads.

In V-Ray Next (4) for 3ds max, a new Metalness parameter has been added to the Reflect parameters of the VRayMtl material.
This allows for easy creation of realistic metal materials and also effectively enables a PBR workflow with V-Ray.
When the Metalness parameter is set to 1.0, the material becomes completely reflective, the Diffuse color controls the general reflection color, and the Reflect color (which should generally be set to white) controls the reflection color at grazing incidence angle.
The IOR parameter still controls how fast will the main reflection color (set by the Diffuse color) blend into the Reflection color, and I don’t know whether some form of complex Fresnel has been implemented or if it’s just a dielectric simple Fresnel blended over a reflective surface.
