Object Brush is the primary interactive painting tool for GameObjects and Terrain Objects in MegaWorld. You paint directly in the scene view while the same shared systems — filters, transforms, scatter, and overlap checks — that power the procedural tools run on every stroke.

​
The most realistic spawn

Object Brush combines manual painting with the full MegaWorld placement stack — filters, transforms, overlap checks, and scatter. Every stroke respects the same rules as procedural passes, so hand-painted areas blend naturally with stamper-generated results. Object Brush painting objects with realistic filter-driven placement.

​
Shared settings with Object Stamper

Types in MegaWorld are reusable presets. A Type configured in Object Stamper can be used directly in Object Brush with no extra setup. Build your rules once in the stamper, then hand-paint with the same rules in the brush. MegaWorld Type preset shared between Object Stamper and Object Brush.

​
Live visualization

Object Brush draws a preview in the scene view while you hover:
  • With a Mask Filter active, the filter output is overlaid on the terrain inside the brush circle.
  • With Simple Filter selected, a handle-based preview of the placement area is shown.
Visualization settings are configured globally in Preferences. Object Brush mask filter visualization in the scene view. Object Brush simple filter visualization in the scene view.

​
Spherical spawn support

Enable Spherical mode to paint on non-terrain surfaces such as sphere geometry or curved meshes. In spherical mode, Mask Filters are replaced by Simple Filter, and only compatible scatter algorithms are available. Object Brush spherical spawn mode painting on curved surfaces. Object Brush spherical mode settings.

​
Cell support

Placed objects are stored in spatial cells. This enables Overlap Check Settings, and makes tools like Brush Erase and Edit aware of exactly where each object was placed. Object Brush cell support overview.

Overlap Check Settings visualization

MegaWorld can draw Overlap Check shapes directly in the scene view. To enable the preview, turn on Visualize Overlap Check Settings inside Precise Place. Overlap Check Settings visualization in Object Brush.
