Ymir
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.
