## Wood

### Color

Parameter ID: `SLA_BANZI_WOOD_GRADIENT`

Colorizes the ring and grain function. Experimentation is required to fully understand and use this control.

### Ring intensity

Parameter ID: `SLA_BANZI_WOOD_RING_INTENSITY` · Range: [-∞..+∞%]

Reduces or increases the prominence of the annual rings. While the parameter can go negative, its useful values are between 50% and 150%.

### Ring Scale

Parameter ID: `SLA_BANZI_WOOD_RING_SCALE` · Range: [0..+∞%]

Scales the rings of the wood before being stirred by the turbulence function.

### Ring Turbulence

Parameter ID: `SLA_BANZI_WOOD_RING_TURBULENCE` · Range: [0..+∞%]

### Turbulence Scale

Parameter ID: `SLA_BANZI_WOOD_TURBULENCE_SCALE` · Range: [0..+∞%]

Stirs the annual rings so they may have a more natural look. Turbulence Scale simply scales the noise used for the ring turbulence.

### Ring Variance

Parameter ID: `SLA_BANZI_WOOD_RING_VARIANCE` · Range: [0..+∞%]

Varies the width of the rings without changing their respective positions.

### Core Variance

Parameter ID: `SLA_BANZI_WOOD_CORE_VARIANCE` · Range: [0..+∞%]

Disturbs the origin of the rings so it looks as if the tree the wood came from did not grow perfectly straight.

### Variance Scale

Parameter ID: `SLA_BANZI_WOOD_VARIANCE_SCALE` · Range: [0..+∞%]

Scale of the noise used to disturb the origin of the rings.

### Radial Variance

Parameter ID: `SLA_BANZI_WOOD_RADIAL_VARIANCE` · Range: [0..+∞%]

Causes the rings to become asymmetrical around their origin. Trees rarely grow perfectly circular rings because they are rarely perfectly round. This parameter allows for the natural deformation of the annual rings.

### Variance Scale

Parameter ID: `SLA_BANZI_WOOD_RADIAL_VARIANCE_SCALE` · Range: [0..+∞%]

Scales the noise used for the Radial Variance.

### Grain Intensity

Parameter ID: `SLA_BANZI_WOOD_GRAIN_INTENSITY` · Range: [-∞..+∞%]

Amplifies the grain pattern within the wood. A percent value of zero removes the grain totally, while a value of 100% gives a very amplified grain pattern (this also affects bump).

### Grain Scale

Parameter ID: `SLA_BANZI_WOOD_GRAIN_SCALE` · Range: [0..+∞%]

Scales the grain.

### Attenuation

Parameter ID: `SLA_BANZI_WOOD_ATTENUATION` · Range: [0..+∞%]

The amount of detail reduction caused by the function becoming smaller (whether being scaled or being further away from the camera) and facing away from the camera. For still imagery, keep this value low (zero is often best), but keep it high for animation (anywhere between 100% to 1,000%+).
