Infinity Generation vs Ymir

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.

Ymir is a node-based procedural terrain generator for Linux and Windows, with a graph workflow for constructing and exporting terrain. Nodes cover noise and shape generation, sculpting, filters, and thermal, hydraulic, and stream erosion. Erosion can use a mask and produce flow, wear, and deposition layers for later terrain work. Projects are stored as readable JSON in .ymir files, and node networks can be saved for reuse as .ymirsub subgraphs. Heightmaps export as 16-bit grayscale PNG, raw 16-bit R16, or 32-bit float EXR. The headless ymir-cli can build saved projects and export results; erosion runs on a GPU when available and otherwise falls back to the CPU. The editor requires a GPU with working Vulkan drivers on Linux, or Vulkan or DX12 drivers on Windows. Ymir is free software under GPL-3.0. Windows binaries are unsigned and prompt a first-run SmartScreen warning.
