leather

Go to: Related nodes. Attributes.

The Leather texture can be used to simulate a wide range of reptile and animal hides. Used as a bump map it can simulate anything from fine-grained concrete to cobblestones. The texture itself consists of a collection of spheres (also called cells) suspended in a medium.

You get the best animal-skin effect by using Leather both as a color and a bump map.

Aside from the attributes listed here, Leather inherits many attributes from Texture3d.

In the table below, important attributes have their names shown in bold in the Description column.

Long name (short name)	Type	Default	Flags
refPointObj (rpo)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointObjX (rox) float 0.0 The x component of the current reference sample position
refPointObjY (roy) float 0.0 The y component of the current reference sample position
refPointObjZ (roz) float 0.0 The z component of the current reference sample position
refPointCamera (rpc)	float3	0.0, 0.0, 0.0
The current reference sample point that has to be shaded
refPointCameraX (rcx) float 0.0 The x component of the current sample position
refPointCameraY (rcy) float 0.0 The y component of the current sample position
refPointCameraZ (rcz) float 0.0 The z component of the current sample position
cellColor (ce)	float3	0.373, 0.157, 0.059
Cell Color controls the colors of the cells in the leather texture. The texture consists uf a series of spheres (cells) imbedded in a medium.
cellColorR (cer) float 0.0 The red value of Cell Color
cellColorG (ceg) float 0.0 The green value of Cell Color
cellColorB (ceb) float 0.0 The blue value of Cell Color
creaseColor (cr)	float3	0.235, 0.118, 0.0
Crease Color controls the color of the space between the cells in the leather texture.
creaseColorR (crr) float 0.0 The red value of Crease Color
creaseColorG (crg) float 0.0 The green value of Crease Color
creaseColorB (crb) float 0.0 The blue value of Crease Color
cellSize (cs)	float	0.5
Cell Size controls the size of the color cells in the leather texture. Increase this to make the cells bigger. If the Leather texture is being used as a bump map, larger values for Cell Size can make it look like cobblestones. Smaller values make it look more like sandpaper.
density (d)	float	1.0
Density controls how many cells there are imbedded in the medium. At 1.0, the medium is completely packed with cells. Reduce this value to make the cells more sparse. If the Leather texture is being used as a bump map, then low values for Density will make it look likea smooth surface with occasional bumps on it.
spottyness (s)	float	0.1
Spottyness controls the randomization of the color of the individual cells. When Spottyness is close to 0, all the cells will be the same color. As you increase Spottyness, some cells will be brighter or darker than others, in a random fashion.
randomness (r)	float	0.5
Randomness controls how the cells are arranged relative to one another. Set randomness to 1.0 to get a realistic random distribution of cells, as would be found in nature. If you set Randomness to 0, all the spots are laid out in a completely regular pattern. This can provide interesting effects when used as a bump map; you can make things like insect eyes, or machine-tooled raspy surfaces.
threshold (th)	float	0.83
Threshold controls the amount that the two colors used in the texture mix into each other. Use low values of Threshold to make the colors blend more smoothly into one another. Use high values to sharply separate the colors into solid dots.
creases (c)	bool	true
Creases. Turn this on to prevent overlapping cells from blending into one another. If this is on there will always be a sharp separation between cells.
