How do I get Creator?

Download Crucible, subscribe to Creator in its Shop, then install Creator from your Apps and press Play.

Can I use it on more than one PC?

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

Is Crucible Heightmap included?

Yes. A Creator plan unlocks Crucible Heightmap too, so one plan covers shaping the land and finishing the map.

What is Creator Mode?

Creator's own custom proc gen, beyond vanilla Rust: it builds on your own land, with the monuments, island pins, bridges and roads you pick. Standard Mode is Rust's own proc gen and builds what a Rust server would from a size and a seed.

Who makes Creator?

Rook makes Creator. You install and update it from Crucible, next to Drizzza's apps.

Does it need Rust installed?

Yes, through Steam. Creator reads the game's art straight from your Rust install.

What PC do I need?

Windows 10 or 11, 64-bit, and a PC that runs Rust. For maps at 4000 or larger, 32 GB of RAM is recommended.

Will the maps work on a normal server?

Yes. Creator saves standard .map files a stock server reads. Volumes, IO wiring, spawn points, loot, vending and NPC profiles, and ziplines need the Creator server extension, which comes with it.

What is the server extension?

An add-on you install on your Oxide or Carbon server. It adds the extras: trigger volumes, IO wiring, spawn points, loot, vending and NPC profiles, ziplines and Deep Sea settings. The rest of your map runs without it. It comes with Creator: press the button next to "Servers need the Creator extension" on Creator's start screen to find it.

Who owns the maps I make?

You do, even after your plan ends. Run them, share them or sell them.
