Procedural Planet Generator PRO creates customizable planets with terrain, oceans, and vegetation, plus a first-person controller, ideal for sci-fi gamesProcedural Planet Generator PRO is a robust Unity asset for creating dynamic, spherical planets with customizable terrain, oceans, and vegetation. It features a procedural generation system using layered noise functions (Perlin-based FBM) to craft varied landscapes with mountains, valleys, and fine details. The asset includes a dynamic Level of Detail (LOD) system for performance optimization, supporting multiple LOD levels based on player distance. Oceans can be generated with adjustable depth and resolution, while vegetation (trees) can be procedurally spawned with customizable density and slope constraints. A dedicated first-person controller aligns gravity and movement to the planet’s surface, enabling seamless exploration with walking, sprinting, and jumping mechanics tailored for planetary environments. Key Features- Procedural Terrain: Generate planets with customizable radius, height, and noise-based terrain (mountains, valleys, details).- Oceans: Optional procedural oceans with configurable materials and resolution.- Vegetation: Procedural tree spawning with adjustable density and terrain slope limits.- LOD System: Optimizes rendering with dynamic chunk-based LOD, configurable for performance.- First-Person Controller: Planetary movement system with gravity aligned to the planet’s center, supporting multi-planet scenes.- Customization: Extensive Inspector settings for terrain, noise, colors, LOD, and performance.- Scalable Objects: Supports scaling of additional objects (e.g., atmosphere) based on planet radius.- UI Integration: Optional UI panels for underwater effects and loading screens. CustomizationThe asset is highly customizable:- Terrain: Adjust noise scales, octaves, persistence, and lacunarity for varied landscapes. Modify height multipliers and domain warping for organic terrain.- Visuals: Customize colors for water, sand, grass, forest, rock, and snow, with slope-based blending and ambient occlusion.- Oceans: Toggle ocean generation, set depth, and adjust resolution.- Vegetation: Use custom tree prefabs or the default simple tree, with control over spawn probability and slope constraints.- Performance: Tune LOD distances, chunk sizes, and collider usage for optimal performance on different hardware.- Controller: Adjust movement speed, jump height, mouse sensitivity, and gravity settings.Suitable GenresThe asset is ideal for:- Sci-Fi Games: Create explorable planets for space adventures, colonization simulators, or open-world exploration.- Simulation Games: Build realistic planetary environments for scientific or educational simulations.- Adventure Games: Design unique worlds for exploration-focused gameplay.- RPGs: Craft immersive planetary settings for quests or survival mechanics.- Sandbox Games: Enable players to explore procedurally generated worlds with varied terrain and vegetation.Use Cases- Single Planet: Create a single, detailed planet for a focused game setting.- Multi-Planet Systems**: Use auto-detection in the first-person controller for seamless transitions between multiple planets.- VR Experiences: Combine with VR systems for immersive planetary exploration.- Procedural Worlds: Integrate into larger procedural generation systems for diverse game environments.Limitations- Requires a material supporting vertex colors for terrain coloring.- Performance may vary in multi-planet scenes; optimize via LOD and chunk settings.- Custom tree prefabs should be lightweight to maintain performance.Procedural Planet Generator PRO** empowers developers to create expansive, visually stunning planets with minimal setup, making it a versatile tool for sci-fi and exploration-focused projects.**Procedural Planet Generator PRO** - Technical Details### Key Features1. **Procedural Planet Generation**: - Generates spherical planets using Perlin-based Fractional Brownian Motion (FBM) noise. - Configurable planet radius (default: 1000 units) and terrain height multiplier. - Layered noise for base terrain, mountains, mega peaks, valleys, and fine details. - Domain warping for organic terrain distortions (adjustable scale and strength). - Seed-based randomization for reproducible results.2. **Dynamic LOD System**: - Supports 1-4 LOD levels with configurable distance thresholds (e.g., 500m, 1200m, 2500m, 5000m). - Chunks per face (1-64) and max vertices per chunk (2-256) for customizable detail. - Asynchronous chunk generation with adjustable updates per frame (default: 2). - Unloading of distant chunks beyond a configurable distance (default: 6000m).3. **Terrain Customization**: - **Base Noise**: Adjustable scale, octaves (1-8), persistence (0-1), and lacunarity. - **Mountains**: Ridged noise with configurable strength and sharpness. - **Mega Peaks**: Rare, high peaks with adjustable rarity and strength. - **Valleys**: Carved terrain with customizable depth. - **Details**: Fine noise for surface variation. - Slope-based rock blending and ambient occlusion for visual depth.4. **Ocean Generation**: - Optional procedural ocean with configurable resolution (4-128) and depth. - Customizable ocean material and level relative to planet radius. - Spherical mesh generation for seamless ocean rendering.5. **Vegetation System**: - Procedural tree spawning on highest LOD chunks. - Configurable tree probability (0-0.1) and max slope for placement. - Default simple tree prefab (cylinder trunk + spherical foliage) or custom prefab support. - Randomized tree scale and rotation for variety.6. **Planetary First-Person Controller**: - Gravity aligned to planet center with optional inverse-square falloff. - Configurable movement speed, sprint multiplier, jump height, and air control. - Mouse-based camera control with adjustable sensitivity, smoothing, and Y-inversion. - Auto-detection of nearest planet in multi-planet scenes with configurable influence range. - Surface-aligned rotation and spawn resolution to prevent geometry intersection.7. **Biome-Like Coloring**: - Vertex color-based system for terrain coloring. - Customizable colors for deep water, shallow water, sand, grass, forest, rock, and snow. - Altitude and latitude-based color transitions (e.g., snow at high altitudes or poles). - Slope-based rock blending and ambient occlusion for enhanced visuals.8. **Performance Optimization**: - Configurable chunk update interval (default: 0.2s) and max chunks per frame. - Optional mesh colliders with distance-based enabling (default: 800m). - Index format support for large meshes (>65,535 vertices). - Efficient memory management with chunk mesh cleanup on destruction.9. **UI and Visuals**: - Optional UI panels for underwater effects and loading screens. - Gizmo visualization for planet radius, LOD distances, and player orientation. - Scalable objects (e.g., atmosphere) tied to planet radius.10. **Custom Spawn**: - Optional spawning of a custom prefab on the planet’s surface at startup. - Aligned to terrain normal for accurate placement.### Technical Notes- **Dependencies**: Requires Unity’s Standard shader or custom shader with vertex color support.- **Compatibility**: Works with Unity 2019.4+ (tested up to 2025.1).- **Performance**: Optimized for single and multi-planet scenes;
