Scattering, but smarter. 🚀
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 within non-destructive workflows that integrate seamlessly with World Partition and existing biomes. It supports realistic, stylized, and low-poly environments.
Why Smart Scatter?
- Speed: Choose to spawn meshes on the CPU or GPU.
- Control: Define rules for slope, height, angle bands (roof/wall/floor), and no-spawn zones or tags.
- Quality: Features natural-looking cluster noise, per-group scale and rotation, and normal-aligned placement with "force look-up" options.
- Scalability: Non-destructive PCG graphs and data-driven presets enable iteration without re-authoring content.
Compatible with Calysto World, Calysto Dungeon, and Calysto Village.
Key Features:
- PCG-First Workflow: Built 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: Aligns 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 floor, wall, and ceiling spawning (−180° to 180° or −90° to 90° modes).
- Row/Spline Generators: Automatically generate even rows (farm/crop style) within 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.
The plugin requires the following Unreal Engine components:
- Procedural Content Generation Framework (PCG)
- Procedural Content Generation Framework (PCG) Geometry Script Interlop
- Scriptable Tools Editor Mode
- Scriptable Tools Framework
PCG is frequently updated across Unreal Engine versions. To fully benefit from Calysto Smart Scatter, it is recommended to use the latest version of Unreal Engine.
