Scene Architect: Procedural Terrain Generator and Spawner Tool

Scene Architect – Procedural Terrain Generator and Spawner Tool

Now generates Terrain in the editor and at runtime if you want.

This is easily the best deal for a terrain generator at $4.99 but that's not all it offers. Scene Architect can also work as a procedural spawning system. You can spawn on a path for your fences to automatically be aligned and spawned properly for example. You can automatically flatten the terrain under the spawned in gameobject to have it sit properly with no effort required on your part. Just point and click. Hold ctrl + alt and left click to instantly spawn a gameobject. Watch the video to see how the spawning works.

Also here is a playable build that shows the terrain generating at runtime and working with Urban Architect Pro V 2.4.

Works with or without terrain.

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?

Scene Architect focuses on fast iteration, practical placement control, and simplicity. It’s built to reduce repetitive manual placement while still giving developers creative control over their scenes.

Typical Uses
