ROVSCAT is a Blender add-on that allows users to scatter objects across mesh surfaces with random variation.
It is designed to help artists quickly populate environments with natural-looking distributions of assets such as rocks, foliage, debris, or props.
ROVSCAT distributes objects randomly across a selected surface mesh.
Example workflow:
Select objects to scatter
Shift-select surface mesh
Click "Scatter Objects"
Objects are automatically placed across the mesh surface.
ROVSCAT supports variation in:
- Position X / Y / Z
- Rotation X / Y / Z
- Scale Min / Max
This helps generate more natural-looking scenes.
Example configuration:
Rotation Z = 360°
Scale = 0.8 – 1.2
ROVSCAT prevents objects from overlapping using a minimum spacing parameter.
Example:
Scatter Count = 150
Minimum Distance = 0.7
For better performance, ROVSCAT can create linked mesh instances instead of duplicating geometry.
Example:
1 mesh
1000 instances
This allows large scatter scenes while keeping memory usage low.
ROVSCAT includes a Random Seed parameter to reproduce or regenerate scatter layouts.
Example:
Seed = 5
Using the same seed produces the same scatter pattern.
- Download the add-on
.pyfile. - Open Blender.
- Go to:
Edit → Preferences → Add-ons
- Click Install
- Select the
rovscat_surface_scatter.pyfile - Enable the add-on.
- Select objects to scatter.
- Shift-select the surface mesh last (active object).
- Open the ROVSCAT panel in the 3D View sidebar.
- Adjust scatter settings.
- Click Scatter Objects.
Terrain environment setup.
Input:
Rock asset
Scatter Count = 200
Scale = 0.7 – 1.3
Rotation Z = 360°
Output:
200 rocks scattered across terrain
