		+	== Important comment from a_c ==
		+	Some lighting and material tips here:
		+
		+	1. Decide what your ship should look like early on. Decide on the type of materials you need for each single part of it. Don't just go with it thinking that you just need to "dress it up" with a texture. If you do, it will most likely end up looking like the texture is a piece of color paper wrapped around a model.
		+
		+	2. Materials are divided into two major categories: metals and dielectrics (i.e. non-metals). Here are some basic guidelines for each:
		+
		+	'''Metals''':
		+	- Specular: Usually white or some shade of gray, values usually in the range of 0.65 - 0.75. Metals can have tinted specular too, e.g. gold, copper. You define this tint in the specular map or with specular_color.
		+	- Gloss: Up to the artist. Experiment until you see something you like.
		+	- Diffuse: Pure metals always have black diffuse color.
		+
		+	'''Dielectrics''':
		+	- Specular: Very low. Usually around (0.04, 0.04, 0.04). Dielcetrics never have tinted specular, unless you are trying to create impossible materials. Things like water have even less specular. For example, the specular value used for the ocean specular reflections in the Lave is Earth OXP is 0.02. Some materials may have slightly different specular values, but normally they are low and materials with specular at around 0.4-0.5 are extremely rare to non-existent. If you are unsure what value to use for your material and you know it is a dielectric, use 0.04.
		+	- Gloss: Depends. Normally on the artist and the appearance they want to achieve. Plastic for example usually has high gloss values but it is not a rule, just a guideline.
		+	- Diffuse: Whatever color your material is. Important - DO NOT include lighting information in a diffuse map - it will look totally off when viewed from the wrong angles. Just put the color of the material there and let the shaders decide on how the lighting will look.
		+
		+	3. The type of material you want to use is not what your object of interest is made of, but what it is on the surface that will reflect the light. Practical example: If your ship is made of titanium and has a coat of paint all over it, the material you want to try to reproduce is paint (which is dielectric) and not titanium.
		+
		+	4. Re normal maps - Try to make details that have a purpose on them. The Arachnid above has a normal map with lots of details, but they are just fluff without purpose. Griff's ships have details on the normal map that seem to outline objects that "do something". The Serpent class above also.
		+
		+	5. Generally speaking, you will get much better results if you use spec and gloss maps rather than numeric values for spec and gloss in the material definition. The reason is that you can describe much better the variations of materials over your surface. You can also describe variations within the same material (e.g. a shiny ship that has a part of a wing that's rusty or dusty - this can be achieved only by texture).
		+
		+	6. Gloss is where an artist has completely free reign. While the other properties are more or less governed by physics, gloss is whatever you want it to be. That is your chance to be truly creative.
