PileGen — Procedural pile & clutter generator for URP. 30+ presets, 13 materials, physics settling, procedural fracture, texture baking. No models needed.PileGen — Procedural Pile & Clutter Generator (URP)Create fully procedural piles of rocks, books, bottles, crates, debris, and more — directly inside the Unity Editor.No models. No textures. No external assets.Every shape, surface, and normal is generated procedurally.⚠ Early Adopter Pricing Price will increase as new features are added. PileGen is currently offered at a discounted early-supporter price. Our target price is $29.99, and it will gradually increase as major features are released.✦ Fully Procedural — Zero External Assets Required All geometry is generated via CPU mesh generation. All surfaces use procedural shaders. Every pile is completely unique. No textures. No third‑party assets. No modeling required.✦ 30+ Ready‑to‑Use Presets Instantly generate:Rock pilesBook stacksBottle collectionsWooden cratesMetal pipesAlchemy potionsKitchen clutterSoda cansTin cansBarrelsWood planksDebrisAnd moreDrag. Drop. Generate.✦ Procedural Fracture System (New in 1.1.1)Shatter any generated shape into realistic shards — no physics engine required.Fracture Shape Modifier Add fracture directly to any shape rule. Composes naturally with the modifier stack — Scatter(5) + Fracture(8) = 40 independent shards per placement.Fracture Pile Action One-click shattering of your entire generated pile in-editor. Shards become independent GameObjects with convex colliders, ready for physics or baking.5 Fracture Styles:Uniform — natural irregular chunks (rocks, concrete)Splinter — long-axis bias (planks, bones)Grid — world-aligned cuts (tiles, masonry)Radial — pie-wedge slices (columns, wheels)Glass — radial + concentric rings (hollow bottles, glassware)Full control per style: Cap Mode (Solid fill or open cuts), Shard Gap, Hide Probability (ruined/damaged looks), Inner Material slot, seed override.✦ 13 Procedural Material Types Each material includes unique surface patterns, procedural normals, and per‑instance color variation (no flickering).
