Features
Drag & Drop — add actors to your scene that auto-generate PCG-driven geometry on placement. Terrain-Conforming Geometry — decals snap to the underlying landscape. High-Resolution Displacement — sculpt layered surface detail using real heightmap-driven geometry. Full Artistic Control — customize material, displacement, falloff, radius, UVs, and resolution—directly from the Details panel. Nanite Baking — convert decals to optimized Nanite-ready static meshes for runtime use. Lightweight & Fast — async PCG means instant feedback and non-blocking edits. Ready-to-Use Examples — includes master material and preconfigured child blueprints for fast iteration.Use Cases
Photoreal terrain stamping — add cliffs, soil, or gravel with full geometric depth.Stylized environments — create layered terrain elements with clean artistic direction.
Lookdev and kitbashing — iterate terrain compositions quickly and visually.
Games and cinematics — add micro-terrain variation without touching the landscape material.
Quickstart
- Make sure to go to Edit->Plugins and enable:
- GeometryScripting
- PCG
- PCGGeometryScriptInterop
- ModelingToolsEditorMode
- Restart your project
- Drag a BP_GeometryDecal_* actor from /Game/PCGGeometryDecals/Demo/Examples/ into your level (these are ready-made variants with materials and textures preassigned) -or- Subclass BP_GeometryDecal and assign your own material + height texture.
- Adjust radius, height intensity, falloff, UV tiling, resolution, etc.
- Select one or more decals and right-click → Scripted Actor Actions → Bake to Static Meshes.
- Enable Nanite on the resulting mesh if needed in the popup window settings.
