QuadSpinner Gaea is a powerful terrain generator that specializes in creating realistic and natural-looking landscapes. With its focus on real-world concepts rather than CG constructs, Gaea allows users to work with mountains, canyons, and craters in a way that is both intuitive and artist-friendly. Gaea’s non-destructive graph workflow enables quick turnarounds and easy minute changes while still maintaining an art-directed look. This procedural terrain workflow is based on natural analogs and is exposed through geo-centric nodes, processors, and simulations.

One of Gaea’s strengths is its flexibility. The procedural nature of Gaea, combined with both high and low-level nodes, ensures that users can always build creative solutions of their own. Gaea allows users to export their terrains as heightfields, using standard ^2 sizes such as 4096 x 4096 and 8192 x 8192. Additionally, for those using Unreal or Unity, Gaea offers options to export to resolutions specific to those engines. Users can also export their terrains as meshes, using either highly optimized decimation or lossless uniform grids. Overall, QuadSpinner Gaea is a versatile and powerful tool for creating realistic and stunning landscapes.

Blender is a versatile open-source 3D modeling and animation software that includes a robust geometry node system. While not specifically designed for terrain generation, Blender’s vast capabilities make it an excellent option for creating all sorts of landscapes, including terrain. To create terrain in Blender’s geometry node system, users can start by adding a subdivide node and then a “set position” node. From there, users can add in Blender’s built-in textures to the “set position” node’s offset input and then multiply the texture with a normal node to achieve the desired terrain effect. Additionally, Blender has a wealth of plugins specifically designed for terrain generation, expanding the possibilities even further. With Blender, the potential for creating unique and intricate terrain is virtually limitless.
