This update adds nebula spheres that do not render clouds along the horizon. These nebula spheres render clouds straight above and straight below when the X rotation and Z rotation of the CUA are set to 0 degrees. A large ground asset is needed to hide the clouds down below. These nebula spheres are labelled "nebula tapered horizon type 1, 2 and 3" in the asset name of the bundle. A new demo scene 4 is included to demonstrate one of the new nebula spheres as illustrated in the last image below.
This update adds a nebula editor that enables the scale, colors and opacity of the nebula spheres to be changed dynamically in your scene. Simply add the nebula_editor.cslist plugin to the CUA.
