Questions

Read the docs Ask on Discord
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.
