System requirements
Creator is a Windows application that reads your own installed copy of Rust.
What you need
Section titled “What you need”| Operating system | Windows 10 or 11, 64-bit. Creator is built and tested on Windows 11; Windows 10 is expected to work and has not been tested here. |
| Rust | Installed through Steam (app 252490) and finished installing, not mid-update. |
| Disk | The app itself. Creator reads your Rust install, so Rust’s files take no extra room. An optional private copy is about 50 GB per Rust build you copy. |
| RAM | 32 GB recommended if you intend to generate maps at 4000 or larger. 16 GB is not enough for those sizes. See below for each map size. |
| CPU | No minimum is published. |
| GPU | No minimum is published. A machine that runs Rust is the sensible starting point. |
Creator does not ship Rust’s art. It reads your Rust install, which is why Rust has to be installed. It never changes your Rust install.
Disk, in more detail
Section titled “Disk, in more detail”By default Creator needs no disk for Rust’s files. A private copy is optional (it keeps Creator on
one Rust build while Rust updates), lives at %LOCALAPPDATA%\Rook\Creator\content\<buildid>\ and is
roughly 50 GB. Creator keeps one per Rust build you have copied, so two or three of them add up
quickly. Removing one you are not using is safe. See
Reclaiming disk space.
Memory needed by map size:
| Map size | Peak memory |
|---|---|
| 6000 | 20.3 GB |
| 5000 | 15.3 to 19.9 GB |
| 4500 | 14.6 to 14.9 GB |
| 4000 | 13.5 to 16.3 GB |
| 3500 | 12.9 GB |
| 3000 | 10.6 GB |
| 1000 | 7.9 GB |
Plan around the high end of the range.
Windows itself usually wants another 2 to 4 GB. So on a 16 GB machine even a 4000 map can run out of room, and a 5000 map does not fit: it pages to disk, which makes generation far slower, and Creator can be killed outright. 32 GB clears every size in the table with headroom.
Restart Creator between large generations if memory is tight.
No CPU minimum is published. Treat generating a large map as something you start and walk away from, and watch the progress rather than a clock: It looks frozen explains what progress looks like.
