Ymir

Ymir is a node-based procedural terrain generator for Linux and Windows, written in Rust. You build terrain by wiring a graph of small, single-purpose nodes: generators lay down base shapes and noise, modifiers sculpt and erode them, selectors and masks scope where effects apply, and endpoints export heightmaps. One data type flows on every edge, so a node drops in anywhere and there is no fixed build order.

Get started

• Install. Build Ymir from source.
• Tutorial. Make your first terrain, start to finish.
• Reference. Every node, world setting, export format, and keyboard shortcut.
• Concepts. The ideas behind the tool: fields, masks, erosion, preview versus build.
