Asset management for hunts
Prepare the banner, map and 3D models a hunt needs, and add the models to your library.
| File | Used by | Needed |
|---|---|---|
| Banner image | The hunt's General tab | Yes |
| Map | The hunt's Treasure Hunt Configuration | Optional |
| 3D model, GLB | Each object, in 3D and AR | Yes |
| 3D model, USDZ | Each object, for AR on iPhone and iPad | Recommended |
| Skybox or environment image | An object's 3D Mode advanced Settings | Optional |
Keep models low-poly and under about 5 MB, so objects open quickly on phones.
