How a heightmap becomes a full map
  1. Crucible Heightmap


    Conjure the land, generate everything Rust needs on top, and export one .map for Creator.

  2. A heightmap

    Every Rust map starts as a grayscale image. Brightness is height.

  3. Becomes terrain

    Beaches, slopes, cliffs and ridges, all from its own custom generator.

  4. Becomes a map

    Biomes, topology, ground textures, lakes and custom-generated cliffs.

  5. Ready to finish

    Add monuments and roads in Creator.


Go back and change any step.

  1. Conjure

    Press Conjure and a whole new map appears. Keep pressing until one fits.

  2. Shape

    Place islands by hand: drag them together, then size and turn each one.

  3. Generate the world

    One button builds the whole map on top of your land.

  4. Export

    One .map that opens in Creator, every layer in place.


Drag the slider. Heightmap on the left, the finished map on the right.

Live 3D view

Rust's ground textures, water and sky, live in 3D. Fly around, paint and sculpt as you go.

Draw your own island

Draw an outline or bring in a picture, and get a whole map in that shape.

Tutorials

What is Crucible Heightmap?

A Windows app for making Rust maps. Generate the land, shape it by hand, then generate the rest on top: biomes, topology, ground textures, forests, lakes, lava and custom-generated cliffs. It all exports as one .map, so Creator opens a finished map instead of a bare heightmap.

How do I add monuments and roads?

Open your .map in Creator. Place monuments, roads and prefabs yourself, or let Creator Mode, Creator's own custom proc gen, place them on your land. Everything you made in Crucible Heightmap comes with it.

What map sizes does it make?

Heightmaps at 513, 1025, 2049 and 4097, the standard Rust sizes. The map size you pick decides which one, and the .map, .raw and .png exports all match it.

What do I need to run it?

A Windows 10 or 11 PC. Download Crucible, open Crucible Heightmap from it, and subscribe in the Shop. Mac and Linux are both planned.

Can I use it on more than one PC?

Up to 2 Windows PCs on one plan. To move to a new PC, deactivate the old one in Crucible first.

Can I sell or share the maps I make?

Yes. The maps are yours, even after your plan ends. Run them on your servers, share them or sell them.

How do I test a map in game?

Load it on your own server with Crucible Local Server, which is free, then join and walk it.
