WorldBrush

WorldBrush — Large-World Object Placement, GPU Rendering & Runtime Streaming Beta Version: WorldBrush is currently in active development. Features, APIs, workflows, and data formats may change in future updates. WorldBrush is a Unity toolkit for placing, generating, baking, streaming, and rendering large numbers of prefab-based objects across large worlds. Key Features - Brush Placement — Paint, erase, and edit prefab instances directly in the Scene View using reusable brushes. - Object Palette — Manage prefabs, materials, LODs, impostors, colliders, categories, and placement settings. - Terrain & GameObject Surfaces — Work with Unity Terrain and collider-backed surfaces divided into manageable chunks. - Procedural Generation — Populate worlds using Jittered Grid, Random, Poisson Disk, Brush Pattern, and Noise Field algorithms. - World Baking — Convert authoring data into binary runtime tiles, manifests, and streaming catalogs. - Runtime Streaming — Load and unload tiles around the player using configurable distance, memory, CPU, and I/O budgets. - GPU Rendering — Supports RenderMeshIndirect, GPU Instancing, and MeshRenderer fallbacks with multi-material and submesh support. - LOD & Impostors — Reduce distant rendering cost with mesh LODs, GPU LOD selection, and camera-facing impostors. - GPU Occlusion — Hi-Z based instance culling without requiring dedicated Unity layers.
