# Licensing
|
|
|
|
Licensing is tracked in four separate layers. Do not merge them; each has different obligations.
|
|
|
|
| Layer | What it covers | Status |
|
|
| --- | --- | --- |
|
|
| Project code | Project-owned code in `Game/Source`, `Tools/`, and `Geo/` scripts | [CC0 1.0](../LICENSE), chosen by the project owner. |
|
|
| Project art | Blender sources, baked textures, exported meshes | Project-owned art is [CC0 1.0](../LICENSE); third-party contributions retain their own terms. See the asset notices. |
|
|
| Engine | Unreal Engine | Proprietary / source-available. Not redistributable as engine source. Distribution follows Epic's terms. |
|
|
| Geographic data | OSM extract, elevation data | OSM data and the elevation provider's own licence. Used for local, private development only. |
|
|
|
|
Project-owned documentation is also dedicated under [CC0 1.0](../LICENSE). Third-party material retains its own terms.
|
|
|
|
## Rules
|
|
|
|
1. An asset whose licence cannot be verified does not get committed. Record it as unresolved in [THIRD_PARTY_NOTICES.md](../THIRD_PARTY_NOTICES.md) and replace it with a redistributable asset before the release it would ship in.
|
|
2. Reference photography is dev-only material and is **never committed**. It lives in the gitignored `Art/reference/` tree, is used for internal, private development only, and is not shipped or baked into shipped textures. Local reference notes are also excluded from version control.
|
|
3. OSM is layout data only. Do not treat it as authoritative for façades, heights, or pavement detail, and do not import it as a texture or panorama source.
|
|
4. Credentials, licence keys, and account tokens never enter the repository. Engine licence acceptance is recorded by date and account email only.
|
|
|
|
## Open decisions
|
|
|
|
- **Reference photography retention.** Decided 2026-11-06: reference images are **not** committed. Licensing is not the gate for local, private development use, so images are simply kept out of the repository (`Art/reference/` is gitignored) and their provenance stays in the local sidecars. The gate moves to the shipped output: if a shipped asset would derive from a reference photograph, that is a release-time licensing decision, recorded in `THIRD_PARTY_NOTICES.md` before the asset ships.
|
|
- **ODbL posture for OSM-derived geometry.** Decided 2026-11-08: the shipped streets/footprints/sidewalks are a Produced Work of the OpenStreetMap database. Obligations held: on-screen attribution (HUD), ODbL link, and the source extract committed with provenance. Share-alike applies to the data layer only; project code and art stay CC0. Full review in [Docs/odbl-review.md](Docs/odbl-review.md).

|
## Provenance sources
|
|
|
|
Primary record: [THIRD_PARTY_NOTICES.md](../THIRD_PARTY_NOTICES.md) for anything committed or shipped. Evidence notes and per-file provenance for local reference images remain private and untracked.
