Atmosphere DialogSome examples of atmospheric tweaking. Pretty much everything on this dialog is self explanatory (or explained on the dialog itself). Only those items which aren't will be explained here. Open/Save. This not only saves all the information on this window, but also the cloud and lighting settings. All these settings are also included in World Files. Density/Decay. A larger value for any of the elements will increase the effect of that element. Lock Colour with Atmospheric Blue (Light Decay). In most situations, the Atmospheric Blue and Light Decay colours should complement each other, and setting this checkbox will result in values which will suit each other well to give Earth-like atmospheres. Edit Colour. You should not have to change the various colours unless you want specific "unusual" effects. The defaults work pretty well for most earthbound scenes. Half-height. The densities of the atmospheric components decrease as altitude increases. Half-heights specify the heights at which the atmospheric components are half as dense as they are at an altitude of zero. Lowering these "flattens" the atmosphere. For example, a low Half-height for Simple Haze can be used to create mist-filled valleys. By lowering Half-heights and increasing the corresponding Density/Decay works well for increasing the "scale" of the scene.
