This change adds support for custom background images.
Usage:
- Background images are stored in "backgrounds" folder as with jpg or png.
- Both 360 degree (equirectangular) and 6-side cubemap images are supported. This is automatically detected based on aspect ratio (with cubemap having 4:3 aspect ratio).
- Select the background from Settings.
Changes:
- The selected background image is persisted in config in this format: "background": "backgrounds/my_background.jpg",
- Image is decoded in a background thread (via Android plugin), as Texture2D.LoadImage can cause multi-second freeze on the UI thread. We then compensate for unity (re-ordering coordinate origin and also alpha channel).
- Made ground smaller & semi-transparent
- Added support for downloading assets (including auto-update)
- By default, auto-update is turned off. Enable it in settings.
- Default repository for app icons and names is [https://github.com/tverona1/QuestAppLauncher_assets]. This can be configured in config.json.
