This model represents a brown dwarf, a large gas giant that was just a bit to small to become an actual star. Even so, it still has enough mass to fuse some of its hydrogen, giving the brown dwarf a dark orange/brown glow. This specific brown dwarf star has a surface temperature fluctuating between 300 and 800 degrees Celsius, giving its hottest areas a red glow like that of glowing hot steel. The cooler clouds do not emit visible light and therefor appear to be black on the shadow sight. Thanks to the HD textures and the low poly construction, this model can be used both as a far away background model, as well as a model for close up use.
Technical information
In real life, this brown dwarf star would have a diameter of around 165.000 km in diameter. Some 3d programs do not display objects of this size very well. In order to avoid complications, and because most users want to decide the exact diameter themselves, the model itself is not scaled to the real life size.
The model consists out of a surface and an atmosphere. The atmosphere creates a slight fade towards the edges of the planet and is made using the facing layer weight node in Blender. Because the node system is different in each 3d program, and because some applications do not need the atmosphere, all export files come in two versions. A version with, and a version without atmosphere.
