Installing GravityCore

Install from Fab

1. Buy or claim GravityCore on its Fab listing.

2. Open the Epic Games Launcher and go to Unreal Engine → Library. Find GravityCore in your Fab Library (called the Vault in older launcher versions).

3. Click Install to Engine and pick your engine version (5.4 to 5.8).

4. Open your project, go to Edit → Plugins, search for GravityCore and enable it.

5. Restart the editor when prompted.

Check that it works

Open the included demo level and press Play. It has a planet, a ring world and a flip-gravity box already set up, and works in single-player and in PIE multiplayer.

The physics demo level shows a planet ringed with props that fall and settle all over its surface.

Test multiplayer in the editor

Set the number of players above 1 in the Play options and run as a listen server. Watch your character from a client: it stays surface-aligned and smooth.

Next: Quick start.
