Synopsis Approximation of woven materials such as satin cloth.
Arguments

"ambient factor" Description: The amount of ambient reflection.
Default:0.1
Hint:[ 0, 1 ]
"diffuse factor" Description: The amount of diffuse reflection.
Default:0.1
Hint:[ 0, 1 ]
"specular factor" Description: The amount of mirror reflection.
Default:0.8
Hint:[ 0, 1 ]
"specular colour" Description: The colour of the specular highlights.
Default:[1.0, 1.0, 1.0]
Hint: [ 0, 1 ], [ 0, 1 ], [ 0, 1 ]
"roughness" Description: The sharpness of specular reflection highlights. The reflection is made sharper with small values for the roughness, such as 0.1. Larger values, such as 1.0, decrease the specular fall-off.
Default:0.1
Hint:[ 0.001, 1 ]
"cylinder distance" Description: The degree of anisotropy of the surface can be controlled by varying the distance between the cylinders. A distance of 0.0 gives isotropic (i.e., the same in all directions) reflectivity, and distance of 2.0 gives maximum anisotropy (i.e., the most directional reflectivity). A distance of greater than 2.0 gives a flat floor between cylinders which reflects light isotropically (evenly).
Default:1.0
Hint:-
"floor height" Description: The height of the floor across the cylinders. A value of 0.0 gives no floor, a value of 1.0 gives a completely flat, isotropic surface (i.e., one that reflects evenly in all directions).
Default:0.0
Hint:-
"bias" Description: Controls the relative contribution of the two directions of threads. For example, cotton is typically woven from two threads, the warp and the weft. These threads are alternated evenly giving equal surface coverage and hence a bias of 0.5. Satin is woven such that either the warp threads pass over more weft threads than they pass under, or vice versa. For a satin weave the ratio of surface coverage between the two sets of threads is 2:1 hence a bias of 0.66 is specified, etc. A bias of 0.0 causes all reflectance to be provided by threads aligned with the s-axis, a bias of 1.0 causes all of the reflectance to be generated by threads aligned with the t-axis.
Default:0.5
Hint:-
"threads" Description: Specifies whether lines representing threads of a material should appear on a surface. 0.0 means that there are no threads while 1.0 means that they are clearly visible.
Default:0.3
Hint:-
"threads thickness" Description: Specifies the thickness of the scratches. The lower the value set, the thinner the scratches will be.
Default:0.006
Hint:[LI_SMALL_06, 0.05]
"threads variation" Description: Controls whether the threads are uniform (0.0) or there is colour variation along lines (1.0 gives the strongest variation).
Default:0.15
Hint:-
"threads variation scale" Description: Specifies the frequency of the variation along the threads. Small values create a grainy effect while higher values create visible lines.
Default:0.2
Hint:[0.05, inf]
