- Working with MegaWorld Window — how to navigate the window
Step 1 — Open the MegaWorld Window and select Advanced Brush
Press Alt + Z to open the MegaWorld Window. In the Tools Panel, click the + button and choose Advanced Brush, or click an existing Advanced Brush instance.Step 2 — Add a Group and prototypes
In the Selection Panel, click Add Type. Inside the Group, click Add Resource and choose Unity/GameObject. Drag your Prefabs (trees, rocks, props) into the prototype list.Add several Prefabs to the same Group. Advanced Brush randomly picks among them while you paint, which naturally breaks up visual repetition.
Step 3 — Configure brush settings
In the Settings Panel, adjust:- Brush Size — controls the radius of the painted area.
- Spacing — controls how far the cursor must move before another spawn point fires during a drag stroke.
- Scatter Settings — choose how spawn points are distributed inside the brush area (random, grid, Poisson disc, and others).
Step 4 — Paint in the scene view
Move your cursor into the Scene View. A circular brush preview shows the area that will be affected.- Click to paint once at the cursor position.
- Click and drag to paint continuously across the scene.
What’s next
- Enable Spherical mode in Brush Settings to paint on vertical or curved surfaces.
