Infinity Generation vs SimpleXTerrain

Infinity Generation's Infinity Engine supports runtime procedural generation of worlds, terrain, vegetation, planets, and other content for games and applications. Infinity Creator is a visual development application with a node graph and 3D scene viewer. Its noise tools are based on FastNoise2 and include Perlin, Simplex, Cellular, and other types. Generated scenes, models, and textures can be exported for use as assets.

The engine is described as compatible with Unity, Unreal, Godot, or custom game engines. Its C++ SDK and API support integration into existing projects, and developers can build custom procedural components for node graphs. Those components can call AI models to enhance dynamic content generation. The Free Alpha plan costs nothing and provides full software use during the Alpha period. Products using Infinity that make over $100,000 in annual gross revenue are subject to a 1% royalty. Creator lists Windows 10 and 11 (64-bit) and requires a Vulkan 1.1-capable graphics card; macOS and Linux are described as coming soon. Free Alpha support is best-effort through community and email. Enterprise includes priority direct support, with price not listed.

SimpleXTerrain is a free, MIT-licensed addon for procedural terrain generation in Godot 4 .NET using C#. Its node graph editor defines heightmaps, biomes, splatmaps, and scattered instances. Heightmap sources include Perlin, fractal, and Voronoi noise, radial shapes, splines, and images. Modifiers include levels, curves, slope masks, hydraulic and thermal erosion, terraces, beaches, ledges, and blur.

At runtime, the addon evaluates terrain chunks asynchronously on .NET background tasks around a moving camera, then streams heightmaps and control maps into Terrain3D regions. The documented workflow uses a Terrain3D node with a camera or character attached to a terrain streamer to build Godot scenes. Requirements are Godot Engine 4.6 or later in its .NET or Mono edition, .NET SDK 8.0 or later, and the Terrain3D plugin. Setup involves copying the addon into the project’s addons directory, rebuilding the C# solution, and enabling the plugin in Project Settings. Foliage and object scattering can generate placement data, but the feature is experimental. Some GPU-capable work has RenderingDevice compute helpers; the documentation identifies CPU evaluation as the reliable path.
