Calysto Smart Scatter - PCG Scattering for Unreal Engine

Calysto Smart Scatter is a powerful PCG‑native scattering tool for Unreal Engine that replaces manual placement with customizable spawning rules (angle, noise, density etc...).

All with non‑destructive workflows that play perfectly with World Partition and your existing biomes.

Works for: realistic, stylized, and low‑poly environments.

Why Smart Scatter?

• Speed: Select if you want to spawn your meshes on the CPU or GPU.

• Control: Rules for slope, height, angle bands (roof/wall/floor), and no spawning zone/tag.

• Quality: Natural‑looking cluster noise, per‑group scale/rotation, and normal‑aligned placement with “force look‑up” options.

• Scalability: Non‑destructive PCG graphs + data‑driven presets let you iterate without re‑authoring content.

Compatible with all the other Calysto tools: Calysto World, Calysto Dungeon, and Calysto Village.

Key Features

• PCG‑First Workflow
  Build with PCG graphs and modular kernels. Non‑destructive, order‑independent, and easy to refactor.

• Smart Cluster System
  Procedural patch/cluster masks with thresholds for natural variation.

• Surface‑Aware Placement
  Align to normals with multiple rotation modes (AlignToNormal, RandomYaw, WorldUp) and a Force Look‑Up option for attached meshes.

• Angle Bands & Slope Filters
  Artist‑friendly world‑space controls for what spawns on floors, walls, and ceilings (−180° to 180° or −90° to 90° modes).

• Row/Spline Generators
  Auto‑generate even rows (farm/crop style) inside a volume with parity offsets (left/right staggering) and density controls.

• Data‑Driven Presets
  Define Groups (flowers, moss, rocks, grass, etc.) with per‑group scale ranges, density, slope max, and noise settings.

• Amazing support

  Be part of a growing Discord community with more than a thousand users and quick support for all my tools.

• Include some realistic nanite vegetation

  Contain a sample of Calysto World 2.0's nanite vegetation collection.
