A library named Terrain Pro meant to run in a Game context, but this build ships with no gameplay or runtime code. It compiles with the auto-generated assembly metadata and two empty source files. There are no systems, assets, or entry points.
Terrain Pro is an editor-only terrain generation and sculpting library. It adds procedural shape functions, noise utilities, a river/stream carver, extra terrain brushes, and a preview/export window that can apply or export heightmaps and splatmaps. It is built around OpenSimplex2S and value-noise helpers and integrates with the terrain editor UI and file export.
