Empyrion Custom Scenario Server Guide
Empyrion scenarios are server content, not just a client subscription. The server must have the scenario folder, the YAML must point at it, and the save must be created against the same scenario version.
Install in the right order
- Download or export the scenario from its trusted Workshop or project source.
- Place the complete scenario folder under the server's
Content/Scenariostree. - Keep the folder name stable; do not rename it casually after a galaxy exists.
- Set the scenario reference in
dedicated.yaml. - Create or restore the save only after the server log confirms the scenario was found.
Scenario versus save
| Change | Usually safe? | Why |
|---|---|---|
| Change server name | Yes | Does not rewrite the galaxy identity. |
| Update a scenario before a new world | Usually | No old save has to interpret the changed content. |
| Change scenario version mid-playthrough | Risky | Existing save data and scenario content can diverge. |
| Rename the active scenario folder | Risky | The save and YAML may no longer resolve the same content. |
For Reforged Eden 2, keep the exact scenario folder identity and version associated with the save. Follow the dedicated Reforged Eden 2 guide for the update path in detail.
Managed Empyrion hosting removes the manual scenario copy step. If a restore is involved, read the save backup guide before starting.
