Facts

Purpose: Ymir is a node-based procedural terrain generator written in Rust.liminalfield.github.io · 30 Sept 2026
Workflow: Its graph uses generators, modifiers, selectors, masks and export nodes, with one data type flowing along every edge.liminalfield.github.io · 30 Sept 2026
Terrain features: The node reference includes noise and shape generators, terrain sculpting and filters, and thermal, hydraulic and stream erosion nodes.liminalfield.github.io · 30 Sept 2026
Erosion: Erosion nodes can read a mask and write flow, wear and deposition layers for later texturing or shaping.liminalfield.github.io · 30 Sept 2026
Exports: Ymir exports heightmaps as 16-bit grayscale PNG, raw 16-bit R16 or 32-bit float EXR.liminalfield.github.io · 30 Sept 2026
Command line: The headless ymir-cli can build saved projects and export results; erosion uses the GPU when available and otherwise falls back to the CPU.liminalfield.github.io · 30 Sept 2026
Project files: Projects use readable JSON in .ymir files, and reusable node networks can be saved as .ymirsub subgraphs.liminalfield.github.io · 30 Sept 2026
Platforms: Ymir runs on x86_64 Linux with Wayland or X11 and Windows 10 or later.liminalfield.github.io · 30 Sept 2026
GPU requirement: The editor requires a GPU with working Vulkan drivers on Linux or Vulkan or DX12 drivers on Windows.liminalfield.github.io · 30 Sept 2026
Windows signing: The distributed Windows binaries are unsigned and trigger a first-run SmartScreen warning.liminalfield.github.io · 30 Sept 2026
Integrity: Linux releases include a SHA256SUMS file covering every release asset.liminalfield.github.io · 30 Sept 2026
License: Ymir is free software under the GPL-3.0.liminalfield.github.io · 30 Sept 2026
Support: The maker directs users whose Linux builds fail on missing system libraries to open an issue with the error, distribution and Vulkan driver details.liminalfield.github.io · 30 Sept 2026
Documentation status: The maker says a guided start-to-finish tutorial is coming and task-focused how-to guides will be added as workflows settle.liminalfield.github.io · 30 Sept 2026
