Rekall Terrain Graph plugin is an advanced graphing system for authoring node-based terrains right inside Unreal Editor. It runs on exactly the same internal architecture as the Rekall MCP Tools plugin, but it gives you not only the whole Rekall terrain framework, but it does so by adding a dedicated graph, allowing you to author terrains of arbitrary complexity using an intuitive node-based system. It is like Blueprints, but for advanced terrains.

Requires Unreal Engine's built-in ProceduralMeshComponent plugin, which is enabled automatically and used only for the in-editor 3D terrain preview.
