Maps

Multiplies the surface offset using a grayscale texture map. Useful for matching objects that require displacement.

Surface Offset Map: Linear Gradient

Multiplies the density using a grayscale texture map, this can be used to vary the density based on a texture. Black completely masks away fur, grey areas reduce the density, and white results in full density.

Density Map: Linear Gradient

Multiplies the length using a grayscale texture map. Black completely masks away fur by giving it a strand length of 0, grey areas reduce the length, and white results in full strand length.

Length Map: Linear Gradient

Multiplies the thickness using a grayscale texture map. Black completely masks away fur by giving it a strand thickness of 0, grey areas reduce the thickness, and white results in full strand thickness.

Thickness Map: Linear Gradient

Overrides the initial growth direction for each strand using a color texture. By default a strand grows out along the surface normal but this map overrides that by setting the growth direction explicitly.

Each color channel of the texture controls a different aspect of the growth direction, exactly like a normal map. A color value of (0.5, 0.5, 1) results in the default direction straight out along the surface normal.

• The Red channel controls the direction along the mesh's U-tangent direction.
  • 0 = fully negative, 0.5 = neutral, 1 = fully positive
• The Green channel controls the direction along the mesh's V-bitangent direction.
  • 0 = fully negative, 0.5 = neutral, 1 = fully positive
• The Blue channel controls the direction along the mesh's surface normal in a binary way.
  • 0 = strand grows along the surface (laying down)
  • 1 = strand grows straight out of the surface

Controls how much strands bend along the Bend Direction Map using a grayscale texture map to control . Black removes the bend direction effect entirely, grey areas reduce the bend direction, and white results in full bend strength.

In the examples below, note how in the areas where the Bend Map is black the Bend Direction has no effect and the strands are only affected by the normal bend due to gravity. In the areas where the Bend Map is lighter the Bend Direction can take effect.

Multiplies the curl amount using a grayscale texture map. Black removes the curl effect entirely, grey areas reduces the curl, and white results in full curl strength.

Multiplies the gravity strength using a grayscale texture map. Black removes the gravity effect entirely, grey areas reduces gravity, and white results in full gravity strength.
