Looking for a SUPER-FAST solution for Blender to build your next terrain? Look no further. This is a perfect tool for Environment Artists, Game Artists, Matte Painters, Concept Artists, and Illustrators. ‘Terrain Mixer’ will give you the ultimate power and speed to create all sorts of terrains for your next project. You won’t believe your eyes when you start moving material sliders left and right.

QUADSPINNER ‘GAEA’ AS AN INSPIRATION
We’re huge fans of the ‘Gaea’ terrain generator. It is a professional tool used by hundreds of top artists around the globe. Since there isn’t any Gaea-to-Blender the bridge available, and tools like Quixel Mixer and Substance Painter (or Designer) only bring unnecessary headaches to the process, we decided to create a ‘Cycles’ material setup that would help us mix heightmaps and diffuse maps fast and easy. If you are serious about terrains you can get your copy of ‘Gaea’ HERE.

HIGH-QUALITY MAPS
We’ll be adding new 8K (16K in the future) height and color maps almost every week. You can also use your own maps.
