Texture Brush is an interactive painting tool dedicated to Unity Terrain texture layers. You paint textures directly in the scene view with mask filter support and per-stroke strength control.

​
Supported resource types

Texture Brush supports:
For stamping terrain textures over a large area procedurally, use Texture Stamper. For painting GameObjects, use Object Brush. For painting grass, use Grass Brush.

​
How it works

  1. Move the cursor over the scene view. The brush circle shows the area that will be affected.
  2. Click to paint once at the cursor position.
  3. Click and drag to paint continuously, spaced according to Spacing in Brush Settings.
Each stroke evaluates the active Terrain Texture prototypes in the selected Group against the current brush area and blends texture strength up to the configured Target Strength.

Features

​
Live visualization

Texture Brush draws a preview in the scene view while you hover:
  • With a single prototype selected and a Mask Filter active, the filter output is overlaid on the terrain inside the brush circle.
  • Otherwise, a simple area preview is drawn.

​
Tool-level controls

​
Texture Brush Tool Settings

  • Target Strength — controls how strongly the texture is painted per stroke, from 0 to 1. Default is 1. Lower values let you build up texture gradually over multiple strokes.

​
Brush Settings

See Brush Settings for brush size, spacing, jitter, and mask type settings.

​
Group-level controls

All active Terrain Texture prototypes in the selected Group are painted on each stroke.

​
Prototype-level controls

  • Mask Filters — restricts painting by height, slope, or terrain texture.

​
When to use Texture Brush

Texture Brush is best when you want:
  • interactive, brush-driven terrain texture painting with precise control over each stroke;
  • building up texture layers gradually with a low Target Strength;
  • adding detail texture work on top of a Texture Stamper pass.
