@ -10,7 +10,6 @@ Technology Preview 2 :
=> Apply model to atmosphere (aerial perspective)
=> Find a proper model for night sky (maybe Shirley)
- Keep skydome lights in cache for a render.
- Add buttons to restore "auto" default values in tabs and dialogs (with several auto presets).
- Clouds should keep distance to ground.
- Rethink the quality settings and detail smoothing in the distance.
=> When quality setting is set to 10, add boost options
