The Opacity property of the BrushSettings class in the Editor.TerrainEditor namespace represents the transparency level of the brush used in terrain editing. This property is a float value that determines how opaque or transparent the brush effect will be when applied to the terrain.
To adjust the opacity of the brush, set the Opacity property to a value between 0 and 1. A value of 0 means the brush is fully transparent, while a value of 1 means it is fully opaque. The property supports incremental adjustments with a step of 0.01.
// Example of setting the Opacity property
BrushSettings brushSettings = new BrushSettings();
// Set the brush opacity to 50%
brushSettings.Opacity = 0.5f;
// Ensure the opacity is within the valid range
if (brushSettings.Opacity < 0 || brushSettings.Opacity > 1)
{
throw new ArgumentOutOfRangeException("Opacity must be between 0 and 1.");
