Simple procedural map generator lets you design terrain by drawing key areas while procedurally generating the rest, combining manual tile placement with Perlin Noise.6000.0.23f1 test completeWhen I first started using Unity, I found it challenging to create terrains in a 3D environment. I wanted a tool that would make terrain generation simple and intuitive. This led me to develop this asset, enabling anyone to easily create beautiful landscapes.Simple Procedural Map Generator is a Perlin Noise-based procedural terrain and tile generator designed as a Unity Editor extension. It allows users to manually draw key areas of the map, while the rest of the terrain is automatically generated using procedural techniques.Key Features:• Drawing-based Tile Placement – Define essential terrain features by directly painting on the grid.• Procedural Terrain Generation – Automatically fills in the map based on user-defined tiles and Perlin Noise.• Terrain & Cube Mode Support – Choose between Unity’s Terrain system for natural landscapes or a grid-based tile approach.• Highly Customizable – Utilize TileTypeData to apply different properties to tiles.• Real-time Editor Preview – Instantly visualize and tweak terrain generation within the Unity Editor.• Procedural Prefab Brush – Automatically place objects and details for richer environments.This tool is perfect for open-world games, sandbox environments, and strategy games, offering a balance between manual control and procedural automation.Detailed Options:1) Map Generator Settings• Width, Height – Set the size of the terrain to be generated.• Map Mode – Select between Terrain and Tile modes.2) Tile Type Container - A container that holds information about tile types.• Includes Terrain Layer• Default terrain height settings• Weight settings – Determines the influence of different tile types within the container.• Prefab Settings:• Is Using Prefab – Toggle whether to use prefabs for this tile type.• Tile Prefab – Assign the prefab to be used for this tile.• Prefab Base Size – Used to properly map larger meshes if they exceed 1x1x1 in size.• Is Groupable – Allows prefabs to merge into larger groups if placed adjacent to each other.• Prefab Base Height – Adjusts the base height of prefabs to align correctly with the terrain.3) Draw Map• Draw Map Size – Adjusts the size of the drawing canvas.• Clear Painted Map – Clears the drawn map.• Selected Draw Tile – Choose the tile type to draw. (Click the tile preview above to select it directly.)• Canvas (Drawing Area):• Left Mouse Click – Paint the selected tile.• Right Mouse Click – Erase the tile.4) Perlin Noise Generator Settings• Random Seed – Generate a new random seed.• Seed – Manually set a fixed seed for map generation.5) Terrain Texture Painter Settings• Blend Radius – Defines how smoothly terrain layers blend (higher values result in more mixing).• Edge Blend Factor – Applies global noise to the entire map (higher values increase randomness).6) Tile Placer Settings• Center Weight – Adjusts the weight of the center tile when blending heights.• Is Flat Height – Debug feature to remove height variations.• Slope Range – Defines the tile range for height blending.• Height Random Scale – Adds random variations to height values.7) Procedural Prefab Brush Container• Name Settings – Assign a name to the container.• Placement System – Choose the placement method:1. INSTANTIATE – Generates objects as GameObjects.2. TREE – Uses Unity’s terrain tree system (for trees).3. DETAIL – Uses Unity’s terrain detail system (for grass and small decorations).• Density – Adjust the placement density.• Object Spacing X, Y – Set the minimum spacing between objects.• Allowed Tiles – Define which tile types allow the placement of this prefab.• Prefabs – List of prefabs to be randomly selected for placement.• Placement System – DETAIL (Grass, Flowers) Only• Textures – Assign texture images for the Unity terrain detail system.• Placement System – INSTANTIATE Only• Use Slope – Applies terrain slope to placed objects.• Editor Extension: Utilizes Unity’s EditorWindow for a seamless workflow• Terrain Generation Methods:-Perlin Noise-based procedural generation- User-defined drawing data for custom terrain shaping• Additional Features:- ScriptableObject-based TileTypeData for managing tile attributes- Integration with Unity’s Terrain Texture & Detail System- Brush tools and prefab auto-placement for detailed environments
