TerraForge is a Blender add-on for procedural terrain generation, developed with flexibility and creative freedom in mind. Built in Python, it allows artists to generate diverse, detailed landscapes directly within Blender, from dense wetland environments and desert formations to arctic mountain ranges, without manual sculpting. The add-on exposes a set of intuitive parameters that control terrain topology, biome characteristics, and surface detail, making rapid landscape iteration possible within a standard 3D workflow. TerraForge is planned for release on BlenderKit and Blender Market, making it accessible to a wider community of 3D artists and environment designers. The add-on is available on GitHub.
