## Ambient

### Color

Parameter ID: `SLA_CHEEN_AMBIENT_COLOR`

Defines the base ambient color used to attenuate (multiply by) the scene ambient color provided by CINEMA 4D. You must have an **Environment object** active in your scene for this to effect your surface at all.

### Intensity

Parameter ID: `SLA_CHEEN_AMBIENT_INTENSITY` · Range: [0..1000%]

Scales the **Color** before it is mixed with the **Edge Intensity** result to create the final ambient color sample that will be used to attenuate the ambient sample taken by CINEMA 4D internally. Appropriate values are 0% - 100%.

### Edge Intensity

Parameter ID: `SLA_CHEEN_AMBIENT_EDGE_INTENSITY` · Range: [0..1000%]

Mixes with Intensity to scale the **Color** to create the final ambient color sample that will be used to attenuate the ambient sample taken by CINEMA 4D internally. Appropriate values are 0% - 100%.

### Falloff

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

Mixes **Intensity** and **Edge Intensity** to attenuate the **Color**. Smaller values provide for more Intensity while larger values provide more **Edge Intensity**. The appropriate range is 0% - 500%.
