This class can render a texture, like a moon texture, and shade this texture to create moon phases. For correct shading, the object in the texture must be round and fill the entire texture (or the entire tile of a packed texture).

This class can further render two glows, where each glow is very similar to a specular Phong highlight. The shape of the glow is defined using an exponent, similar to the specular exponent of Phong-shaded materials. A glow with a high exponent can be used to draw a sun disk.

The position on the sky is defined by the orientation (see PoseWorld) of this scene node. The object will be drawn in the forward direction (-z) of this node. The glows are defined by the properties GlowColor0, GlowExponent0, GlowColor1, GlowExponent1 and GlowCutoffThreshold. To disable a glow, set its glow color to 0. All other properties are only used to define the appearance of the texture. To render only glows, set the Texture to .

Usage examples: To render a moon or a planet, use a moon texture and a single glow. To render a sun, use two glows - one glow with a high exponent to create the sun disk and one glow with a low exponent for a huge highlight. To render any other texture into the sky, use a texture without glows and without a SunLight to avoid moon-phase-like shading.

Cloning: When a SkyObjectNode is cloned the Texture is not duplicated. The Texture is copied by reference (shallow copy). The original SkyObjectNode and the cloned instance will reference the same Texture.
