Fur Materials - Complex

This master material utilizes Unreal 4.11's Hair Shading model, which requires dynamic lighting & shadows in order to visually look correct. Best For projects with:

• Dynamic Lighting & Shadows
• Flexible performance requirements
• Modern hardware

Undercoat Color

• b Color Map UND
  • Enable Control of Undercoat color via a texture
  • If disabled, pure color controls will be utilized
• b Gradient Map UND
  • Enable override of color for Undercoat via a Gradient Map
• Color Map UND
  • Undercoat texture to apply to strands
• Color Map UV Scale UND
  • Amount of UV Scaling to apply to Undercoat color map
  • Default: 1
  • Min: 0.1
  • Max: 24
• Hue Variation UND
  • Amount of Hue Variation to apply per-strand
• Value Variation UND
  • Amount of Value variation to apply per-strand

Undercoat Volume

• b Density Map UND
  • control Undercoat density via a texture.
• b Heightmap UND
  • Enable the use of a heightmap to augment the length of the strands
• b Opaque Base
  • Enable the lowest undercoat layer to be opaque
  • This would prevent "skin" from being visible beneath fur layers
• Density Map UND
  • This texture controls the density of the Undercoat strands
  • Black = No strands
  • White = Maximum strands
• Density Map UV Scale UND
  • Amount of UV Scaling to apply to Undercoat density map
  • Default: 1
  • Min: 0.1
  • Max: 24
• HMP Depth
  • "Depth" of heightmap
  • Lower values = more depth
  • Default: 1
  • Min: 0
  • Max: 1
• HMP Map
  • Heightmap texture augments length of Undercoat fur strands
• HMP UV Scale
  • Amount of UV Scaling to apply to heightmap
  • Larger value = more tiling
  • Default: 1
  • Min: 0.1
  • Max: 24
• Strand Length Max UND
  • Maximum range of Undercoat Strand Length (Default: 0.75 - Min: 0 - Max: 1)
• Strand Length Min UND
  • Minimum range of Undercoat Strand Length (Default: 1 - Min: 0 - Max: 1)
• Strand UV Scale UND
  • Amount of UV Scaling to apply to Strand Map
  • Larger value = Smaller strands
  • Default: 12
  • Min: 1
  • Max: 24

Undercoat Lighting

• b Dither Animated
  • Enable animated dithering effect. Can help edges appear softer and semi-translucent
• Dither Amount
  • Amount of Animated Dither to blend into alpha.
  • Default: 0.25
  • Min: 0
  • Max: 1
• Gradient Map Scatter
  • Gradient texture that gets sampled for random per-strand scattering.
• Roughness UND
  • Roughness value for Undercoat strands.
  • Smaller value = smoother/shinier look.
  • Default: 0.4
  • Min: 0.1
  • Max: 0.9
• Specular Breakup UND
  • Used to "break up" specular reflections - this option adds variance to the tangent output per-strand.
  • Larger value = more breakup
  • Default: 0.4
  • Min: 0
  • Max: 1

Overcoat

• b OVR
  • Enable Overcoat strands and related options

Overcoat Color

• b Color Enable OVR
  • Enable unique coloring control for the overcoat strands.
• b Color Map OVR
  • Enable control of Overcoat color via a texture.
• Color Root OVR
  • Color value to apply to root of Overcoat strands
• Color Tip OVR
  • Color value to apply to Overcoat strands.

Overcoat Volume

• b Density Map OVR
  • control Overcoat density via a texture
• b Heightmap OVR
  • Enable heightmap to affect overcoat in addition to undercoat
  • (Undercoat heightmap must be enabled)
• Density OVR
  • Density of Undercoat strands to draw.
  • Default: 1
  • Min: 0
  • Max: 1
• Strand Length Max OVR
  • Maximum range of Overcoat strand length.
  • Default: 0.75
  • Min: 0
  • Max: 1
• Strand Length Min OVR
  • Minimum range of Overcoat strand length. Defines smallest possible overcoat strands.
  • Default: 1
  • Min: 0
  • Max: 1
• Strand UV Scale OVR
  • Amount of UV scaling to apply to Strand map.
  • Larger value = smaller strands
  • Default: 8
  • Min: 1
  • Max: 24

Overcoat Lighting

• Roughness OVR
  • Roughness value for Overcoat strands.
  • Smaller value = Smoother/shinier look
  • Default 0.3
  • Min 0.1
  • Max 0.9
• Scatter OVR
  • Amount of light scattering for Overcoat strands. Intended to mimic light passing through strands.
  • Default 0.5
  • Min: 0
  • Max: 1
• Specular Breakup OVR
  • Used to "break up" specular reflections - this option adds variance to the tangent output per-strand.
  • larger value = more break
  • Default: 0.4
  • Min: 0
  • Max: 1
