Scene Architect: Procedural Spawner Tool

Scene Architect – Procedural Scene Spawning Tool for Unity

Scene Architect is an editor-focused spawning system designed to quickly populate Unity scenes with props, buildings, vegetation, and environmental details. It helps you place objects faster while maintaining full artistic control, making it ideal for environment design, prototyping, and procedural workflows.

It combines manual placement, path-based spawning, terrain interaction, and rule-based constraints into a streamlined Unity workflow.

Key Features

Fast Scene Population

• One-click prefab spawning directly in the Scene view
• Randomized placement with probability control
• Automatic terrain snapping
• Built-in collision checks to prevent overlaps

Populate environments in seconds instead of hours.

Path-Based Object Placement

• Create curved placement paths visually in the editor
• Spawn objects along paths for organized layouts
• Automatic spacing and orientation alignment
• Ideal for environmental props, buildings, vegetation rows, or decorative elements

Note: Scene Architect does not generate roads or geometry — it places objects along defined paths.

Flexible Spawn Rules

Control exactly where and how objects spawn:

• Spawn probability settings
• Collider-based overlap detection
• Distance-from-path offset placement
• Ground and terrain layer filtering (integer-based setup)
• Random or fixed rotation options

This keeps placements natural and prevents unrealistic overlap.

Terrain Interaction

Optional terrain modification at spawn locations:

• Terrain flattening under spawned objects
• Edge smoothing for better blending
• Vegetation clearing
• Adjustable terrain modification area per object

Useful for placing buildings, props, and structured elements on uneven terrain.

Runtime Spawning Support

Scene Architect is primarily an editor tool but also supports:

• Manual runtime spawning via script
• Collision-aware placement
• Procedural or gameplay-driven spawning setups

Bonus Terrain Texturing Tool

Includes a simple automatic terrain texturer:

• Sand below sea level
• Grass above sea level
• Rock on steep slopes

Quick way to texture terrains for prototypes or base environments.

Designed For

• Solo developers
• Environment artists
• Level designers
• Procedural generation workflows
• Rapid prototyping projects

Why Scene Architect?
