0.9.5
World properties have been moved into a new dialog, available with the Edit > World Settings menu.
Editor now supports a single directional light, in the world settings dialog.
No changes were made to the way directional lights work in the engine / API. They are still just a normal entity.
Fog settings are available in world settings.
Post-processing effects are available in world settings. Some of my post-processing shaders are not very good and need work.
Some environment settings like the cubemaps used need to be set again, as they will not be loaded from existing maps. All these types of properties have been moved into an "Environment" block in the JSON structure.
Fog and post-effects will be applied to all cameras that are created inside a call to LoadMap, whether the camera is loaded from the map or created in code with a component.
