Tool Settings





Tool Strength

Controls how much smoothing occurs with each brush stroke.

Filter Kernel Scale

Sets the scale multiplier for the smoothing filter kernel for the radius that smoothing will be performed over. Higher values smooth out bigger details, while lower values only smooth out smaller details.

Detail Smooth

If checked, performs a detail-preserving smoothing using the specified detail-smoothing value. Larger-detail smoothing values remove more details, while smaller values preserve more details.
