| Command line | The command-line interpreter can load project and terrain files, convert more than 65 formats, and run through batch files. | The headless ymir-cli can build saved projects and export results; erosion uses the GPU when available and otherwise falls back to the CPU. |
| Platforms | The maker says TerreSculptor is available for Windows only; it reports testing it on Mac using Parallels Desktop with a Windows virtual machine. | Ymir runs on x86_64 Linux with Wayland or X11 and Windows 10 or later. |
| Purpose | TerreSculptor is terrain software for creating and editing heightmaps, weightmaps, splatmaps, masks, digital elevation models, and more. | Ymir is a node-based procedural terrain generator written in Rust. |
| Support | The maker offers support through Discord, a Facebook group, and support email. | The maker directs users whose Linux builds fail on missing system libraries to open an issue with the error, distribution and Vulkan driver details. |

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.
