<!-- Reflections

PARAMETERS: There are two forms of cube map texture:- vertical cross and 6 images.
Either can be used - alternative forms are shown in <parameters> and in <texture-unit>

The reflection is set proportional to the shininess of the material. Thus by 
varying the material shininess value over or between objects the amount of 
refection can be controlled. The overall amount of reflection may be 
adjusted by the use of <refl_correction> -1.0 (fully transparent)- 1.0 (fully opaque).

The overall values of the coloured fringing or fresnel effect may be adjusted
by the use of <rainbowiness> and <fresneliness>.

If your result is too dark/too light the overall ambient light value can be adjusted
by the use of <ambient_correction>. This correction also takes out some of the blueness
added as default to compensate for the lack of reflection.

USE: 	To use the default reflection effect (controlled by material shininess values) use 
	
	<effect>
			<inherits-from>Effects/reflect</inherits-from>
			<object-name>Fuselage</object-name>
	</<effect>
	
			To use your own reflection effectuse
			
	<effect>
		<inherits-from>Aircraft/Lightning/Models/Effects/lightningreflect</inherits-from>
		<object-name>Fuselage</object-name>
	</<effect>
	
in your model file.

To use your own effect place your efffect file containing something like this:

	<name>Effects/lightningreflect</name>
	<inherits-from>Effects/reflect</inherits-from>
	
	and the the modified tags in the path as above

EXAMPLES: You can find examples of both usages in the Hunter and Lightning models.
