SplineLand is a professional, commercial plugin from iCube R&D Group designed for creating topographically accurate terrains and roads from splines within Autodesk 3ds Max. It is recommended to acquire the software directly from the developer, rather than through unofficial blog posts, to ensure security and compatibility with 3ds Max, which extends to version 2026.
