Adding support for 2D texture that represents 6-sided cube (2048px per side) as a horizontal layout:
[ +x ] [ -x ] [ +y ] [ -y ] [ +z ] [ -z ]
This is the recommended representation of cube map as it is more efficient in terms of memory.
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
