Brush Settings define the shape and behavior of scene-view brush interaction in MegaWorld. Different tools use different brush variants, but they all build on the same core idea: brush size, spacing, and a mask that defines the affected area.

​
Core settings

  • Brush Size — the diameter of the brush area in the scene view. Default is 100.
  • Spacing — the distance between consecutive brush marks while dragging.
Resize the brush with Shift + Mouse Wheel.

​
Brush Spacing

Controls how frequently brush marks are applied as you drag the mouse.
  • Brush Spacing Equals Type — determines how the spacing distance is calculated:
    • Half Brush Size — spacing equals half the current brush size. This is the default.
    • Brush Size — spacing equals the full brush size.
    • Custom — uses the Brush Spacing value below.
  • Brush Spacing — the custom spacing distance used when Brush Spacing Equals Type is set to Custom. Default is 30.

​
Mask Types

Determines the shape of the brush mask applied to the painted area. Custom Brushes — use a custom texture as the brush mask. Right-click in the mask picker to access brushes bundled with MegaWorld, or import your own textures. Procedural Brush — generate a mask from mathematical parameters instead of a texture:
  • Shape — the geometric form of the mask (circle, square, diamond, etc.).
  • Brush Falloff (%) — controls the gradient falloff from the center to the edge of the brush.
  • Brush Strength (%) — the maximum influence value at the center. Lower values produce softer marks.
  • Fractal Noise — adds procedurally generated noise to the mask for an organic, irregular edge.

​
Brush Jitter

Controls scatter and randomness of the brush stroke itself. All values are clamped to 0–1.
  • Brush Size Jitter — reduces the effective brush radius by a random amount each stroke. At 0 the radius is unchanged. At 1 the radius can be reduced by up to the full brush radius.
  • Brush Scatter — offsets the brush center position by a random direction. The offset distance is BrushRadius × Brush Scatter. At 0 there is no offset.
  • Brush Scatter Jitter — adds variability to the Brush Scatter amount. Reduces the scatter distance by a random fraction each stroke.
  • Brush Rotation Jitter — randomizes the rotation of the brush mask each stroke. At 0 the rotation is fixed. At 1 the rotation varies by the full brush rotation value.

Preferences

The brush system also has preference-level settings:

Where Brush Settings are used

If a brush tool feels too dense or too sparse, check Brush Size and Brush Spacing Equals Type before changing the deeper placement logic.
