 |
|
 |
User Seed |
This parameter controls the seed for the whole pattern. By changing its value different patterns can be created.
|
 |
|
 |
Leather Levels |
This parameter controls the number of leather grain patterns there are. The bigger this value the
denser the leather pattern.
|
 |
 |
 |
Lower Limit |
This parameter controls where the valleys of the leather grain pattern start. By adjusting
this value, in conjunction with the upper limit, different grain patterns can be created.
|
 |
 |
 |
Upper Limit |
This parameter controls where the valleys of the leather grain pattern finishes. By adjusting
this value, in conjunction with the lower limit, different grain patterns can be created
|
| Common Parameters |
 |
|
 |
Noise Magnitude
 |
The Noise Magnitude controls the size of the Turbulence that is used to "stir" up the texture.
As the Magnitude value is increased the amount by which the pattern is disturbed is increased.
|
 |
|
 |
Noise Scale
 |
The Noise Scale parameter controls the frequency of the turbulence, that is the periodic frequency.
When the scale is at a high value the turbulence will be tight and crinkled and will become increasingly
smoother as this parameter is decreased.
|
 |
|
 |
Noise Octaves
 |
The Noise Octaves parameter controls the number of times noise is summed in order to generate the turbulence.
Turbulence is generated by summing noise with each summed noise being half the magnitude of the previously summed
noise. The number of times the noise is summed is determined by octaves. So, at low values the turbulence will
be smoother and will increase in detail (due to the fact that the summed noise is getting smaller) as the
number of octaves is increased. All this basically means is that the turbulence becomes more "crinkled"
as the number of octaves is increased.
|
 |
 |
 |
Noise Omega
 |
The Noise Omega parameter controls the granularity of the turbulence and is only used when it is non-zero. The higher
the value the more granular the turbulence.
|
 |
|
 |
Noise Velocity
 |
The Noise Advection parameter controls the speed of the noise over the whole animation cycle.
Basically, the higher this value the more active the noise is.
|
 |
 |
 |
Noise Time
 |
The flow noise can be animated by morphing the Time parameter.
|
 |
 |
 |
Brightness
 |
This parameter controls the overall brightness of the pattern in much the same way
as the brightness control on a television.
|
 |
 |
|
Contrast
 |
This parameter controls the overall contrast of the pattern in much the same way
as the contrast control on a television.
|
 |
 |
 |
Lower Clip |
This parameter sets the lower limit for the actual texture function. This allows the function to be clipped or parts of it expanded.
|
 |
 |
 |
Upper Clip |
This parameter sets the upper limit for the actual texture function. This allows the function to be clipped or parts of it expanded.
|
 |
 |
|
Blend Function |
This link only parameter controls the blend function used by the texture. By linking it
to say a generator the profile of the blend can be altered.
|
| Color Only Parameters |
 |
 |
 |
Low Color |
This parameter sets the start color for the texture pattern.
|
 |
 |
 |
Leather Color |
This parameter sets the leather color for the texture pattern.
|
| Percentage Only Parameters |
 |
 |
 |
Low Percentage |
This parameter sets the start percentage for the texture pattern.
|
 |
 |
 |
Leather Percentage |
This parameter sets the leather percentage for the texture pattern.
|
| Bump Only Parameters |
 |
 |
 |
Low Bump |
This parameter sets the start bump height for the texture pattern.
|
 |
 |
 |
Leather Bump |
This parameter sets the leather bump height for the texture pattern.
|
 |
 |
 |
Bump Scale |
This parameter controls the overall scaling of the bump height. When it is positive it
controls the height of the bumps and when negative it controls the depth of the pits.
