Detailed Description

A layer of clouds which change shape over time and are affected by scene lighting.

CloudLayer always renders overhead, following the camera. It is intended as part of the background of your level, rendering in front of Sky/Sun type objects and behind everything else.

The illusion of clouds forming and changing over time is controlled by the normal/opacity texture and the three sets of texture animation parameters. The texture is sampled three times. The first sample defines overall cloud density, where clouds are likely to form and their general size and shape. The second two samples control how it changes over time; they are combined and used as modifiers to the first sample.

CloudLayer is affected by scene lighting and is designed to be used in scenes with dynamic lighting or time of day changes.
