What unity_terrain_export_heightmap does on Unity MCP Server

RISK

Why unity_terrain_export_heightmap is rated Medium

This tool creates or writes files (RAW or PNG) from existing terrain data. While it modifies the filesystem, it is not destructive in nature—the original terrain data in the Unity project remains intact, and the operation is reversible (files can be deleted or re-exported). It has no impact on the project's core assets or buildable state. Low severity due to limited blast radius and reversibility of file output.

From the tool's definition Tool exports terrain heightmap data to RAW or PNG file formats. The word 'export' combined with file output indicates data is written to disk in a new or overwritten file.
