Installing PlanetGen

Install from Fab

1. Buy or claim PlanetGen on its Fab listing.

2. Open the Epic Games Launcher and go to Unreal Engine → Library. Find PlanetGen 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 PlanetGen and enable it.

5. Restart the editor when prompted.

Check the engine plugins

PlanetGen depends on ProceduralMeshComponent and EnhancedInput. Both ship with Unreal Engine 5 and are enabled by default. If you have turned either off in your project, turn it back on under Edit → Plugins.

Check that it works

Open one of the demo levels and press Play:

Level	Shows
PlanetMap	A fully configured planet
PlanetMap_Atmos	A planet with atmosphere and volumetric clouds
PlanetsMap / MultiPlanetsMap	Several planets with LOD handoff and per-planet atmospheres
RingMap	A ring world

Using other CodeLikeMe plugins?

PlanetGen installs cleanly in the same project as WorldGen and CityGen. Every PlanetGen class, struct, enum and header is uniquely prefixed (PlanetGen…, CLMPlanet…), so nothing collides.
