RealWorld Ultimate Terrain Builder

Pipeline: Built exclusively for URP.

Dependencies: No external plugins required.

RealWorld: Procedural Ecosystem Builder

Build lush, dynamic, and highly optimized environments directly in the Unity Editor. Designed specifically for the Universal Render Pipeline (URP), RealWorld is a modular ecosystem generation suite that empowers you to sculpt terrain, paint intelligent flora, and generate procedural details with absolute precision.

Whether you are designing a cozy shop simulator or a sprawling open-world MMO, RealWorld delivers AAA-quality environments without destroying your framerate.

🛠️ Core Modules

• Terrain Sculptor: Sculpt volumetric plateaus, cliffs, and valleys using spline-based pathing. Instantly adjust cliff steepness, inner-deformation, and blending, then paint up to 4 layers of textures with a custom Splatmap system.
• GPU Flora Painter: Paint dense forests and grasslands using intelligent placement rules that respect terrain slopes and minimum spacing to prevent overlapping.
• Dynamic Density Scaling: Flora automatically adapts to its environment. Plants shrink into small bushes on the edges of paths, but automatically scale up into massive trees when surrounded by neighbors.
• Procedural Rock Scatterer: Automatically detect cliff faces to generate combined procedural rock formations, or manually paint custom rock prefabs directly onto the terrain.
• Spline River Builder: Draw seamless, flowing rivers with adjustable width, depth, and subdivision settings that automatically snap into continuous loops.
• RealSun Day/Night Cycle: A complete 24-hour time-of-day system with adjustable orbit tilts, dynamic gradients, and smooth blending between sun and moon light sources.
• Interactive Wall Builder: Click and drag to construct, resize, and shape structural walls natively in the Scene View.

⚡ Extreme Optimization

• Zero-GameObject Instancing: With a single click, convert tens of thousands of painted flora GameObjects into highly performant GPU instances using Graphics.DrawMeshInstanced, keeping your hierarchy perfectly clean.
• Custom Distance Culling: Bypasses Unity's standard LODGroup system for a heavily optimized, absolute-distance mesh swapper that culls chunks and seamlessly scales down distant geometry to zero.
• Advanced URP Shaders: Includes a custom vegetation shader featuring multi-axis organic wind flutter, random position-based color variation, and math-driven Subsurface Scattering (SSS) translucency that correctly reacts to shadows.
