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.Annotation 2019-11-22 185652.jpg

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.

V-Ray for 3ds max Wood Floor Material

An example of varnished wood floor material in V-Ray and 3ds max.
The material uses a VRayBlendMtl with 2 connected VRayMtl sub materials to simulate a natural wood base layer coated by a glossy varnish layer.

Explanation of the material node graph:50770279_2476404922388832_853261524695777280_o.jpg

  1. The wood color (Diffuse texture)
  2. The wood black and white detail texture (used to add reflection detail)
  3. The wood bump texture (actually the same as the reflection texture just color corrected to whiten most details except the lines separating the wood planks)
  4. The reflection texture is color corrected to to intensify it prior to it being connected to the base wood layer material:

  5. The reflection texture is color corrected to to decrease its intensity prior to it being connected to the varnish coat blend:

  6. The base layer natural wood material with the Diffuse, Reflect and Bump textures connected to it:

  7. The varnish coat material with the Bump texture connected to it:
    * Note the Fresnel Reflections is turned off because the Fresnel reflection is calculated by the Falloff map (8)

Simple Snow Material in VRay for 3ds max

Software:
3ds max 2019 | V-Ray Next

A simple way to create a snow material in V-Ray for 3ds max is to combine a VRayFastSSS2 material with a VRayFlakesMtl using a VRayBlendMtl.
The VRayFastSSS2 creates the soft translucent shading for the snow, and the VRayFlakesMtls adds sparkling highlights.

  • Note that depending on the scene and view scale,
    The VRayFlakesMtls ‘flake glossiness’, ‘flake density’ and ‘flake size’ have to be tweaked to achieve the wanted result.
