Geology Map is a Vintage Story mod by cooli2. Geology Map adds a client-side map layer that reveals the first visible rock and shows its name when you hover over it.
Why this mod is worth installing
Useful for locating specific stone types, planning mining trips, and finding suitable areas for farming non-economic rocks. Since it runs client-side, it can be used on multiplayer servers without server installation.
What Geology Map adds
Geology Map adds a separate layer below the terrain layer. Once enabled, it colors the map according to the first stone block visible at the surface, making broad geological patterns much easier to recognize than by exploring blindly.
Hovering over a colored area displays the corresponding rock name. An opacity control lets you blend the geology overlay with the normal terrain map, so landmarks and geological information can remain visible together.
The layer is disabled by default and can be adjusted when needed. Suevite is hidden by default because its presence is closely associated with meteoric iron, but this behavior can be changed in the configuration.
The mod renders geology data on the client and stores information for processed chunks. In an existing world, coverage grows only as chunks are viewed after installation, so the complete geology map will not appear immediately.
