About Terrain Mixer

Terrain Mixer is a shader‑based terrain generator for Blender developed by zets. It operates through a node‑based system that leverages both Cycles and Geometry Nodes, enabling artists, game developers, matte painters, and illustrators to create realistic or abstract terrains directly in the 3D Viewport. The add‑on can mix up to nine height inputs using custom node groups, and its Erosion Mixer simulates erosion by blending multiple heightmaps. Users can fine‑tune terrain features with image masks and node rotations, and a bake‑to‑texture workflow lets heights and diffuse textures be exported for game engines or other applications. High‑resolution assets are available as a free download from Blender’s N‑panel. Terrain Mixer is compatible with Blender 4.2 LTS and newer and is released under the GNU GPL v3.0 or later.
