Overview
The Denoise filter reduces noise in your terrain. Depending on the level step it is working on, this can affect larger or smaller-scale noise.
Parameters
- Deviation
The deviation controls the scale for the detection of noise.
- Threshold
Everything detected noise under the threshold parameter will be smoothed, allowing you to control the amount of noise that will be smoothed.
- Radius
The amount of pixels taken into the smoothing operation.
Results
 small scale denoise effect |  stronger smoothing |
