Terrain Mixer earns its place in the blender_extensions library for pairing a Cycles shader workflow with Geometry Nodes, including a dedicated Erosion Mixer and a bake-to-texture path.
Terrain Mixer is a terrain generation system for Blender built by zets, working through a node-based workflow that draws on both Cycles and Geometry Nodes. It is aimed at artists, game developers, matte painters, and illustrators, and lets you create realistic and abstract terrains directly from the 3D Viewport.
The add-on can combine up to nine height inputs using custom node groups. Its Erosion Mixer, a Geometry Nodes setup, simulates erosion effects by blending multiple heightmaps. Image masks and node rotations allow you to fine-tune individual terrain features, and a bake-to-texture workflow lets you render terrains and bake heightmaps and diffuse textures for use in game engines or other applications.
High-resolution assets are available as a free download from inside Blender's N-panel. Terrain Mixer is compatible with Blender 4.2 LTS and newer and is distributed under the GNU General Public License v3.0 or later. Version 3.1.3 replaced the default heightmaps with new ones, keeping the old ones in the same directory, and adjusted the height input Scale sliders.
Terrain Mixer is best for artists, game developers, matte painters, and illustrators building realistic or abstract terrains in Blender.
Terrain Mixer is completely free to download and use.
Terrain Mixer is compatible with Blender 4.2 LTS and newer, so version 4.2 is supported along with later releases. The current version is 3.1.3. If you are on a version older than 4.2 LTS, you would need to update Blender before installing. You can add the extension by dragging and dropping it into Blender or by downloading it and installing from disk. For details on newer builds, check the developer's page.
Terrain Mixer is a shader-based terrain generator built for Cycles, and it uses a node-based workflow that draws on both Cycles and Geometry Nodes. The Erosion Mixer in particular is a Geometry Nodes setup that blends multiple heightmaps. Because the system is centred on these tools, you work with Cycles and Geometry Nodes to build and refine terrains. For specifics on render settings, see the documentation and tutorials linked on the developer's page.
Terrain Mixer can combine up to nine height inputs using custom node groups, which lets you build layered terrain compositions. It also includes an Erosion Mixer, a Geometry Nodes setup that simulates erosion by blending multiple heightmaps. You can fine-tune the result with image masks and node rotations to control individual terrain features. Version 3.1.3 replaced the default heightmaps with new ones and adjusted the height input Scale sliders.
Terrain Mixer offers high-resolution assets as a free download from inside Blender's N-panel. There are also separate high-res height inputs available as heavy 8K EXR files, which are distributed outside the main package because of their size; the file names match those inside the package, so you can replace the defaults with them. For links and help, refer to the developer's page and documentation.
Terrain Mixer is listed as free here and is distributed under the GNU General Public License v3.0 or later. You can obtain it by dragging and dropping it into Blender or by downloading it and installing from disk. For the current licensing terms, additional downloads, and any support options, check the developer's page. If you need help replacing the default image files with your own, the developer invites you to get in touch.
