Known Types

128-byte Sections

Actual usage of the light parameters varies by type of light, as follows:

Type	Name	F7	F8	F9	F10	F11	F12	F13	F14	F15	...
0x03	Point	Y	-	-	-	-	-	-	-	-	...
0x04	Spot	Y	Y	Y	Y	Y	Y	-	-	-	...
0x07	Window	?	-	-	-	-	-	-	Y	Y	...
0x09	Area	?	-	-	-	-	-	-	Y	Y	...

Notes

Intensity affects decay (how far the light reaches) rather than apparent brightness at source. Use the colour (rgb) settings to make softer lighting.

56-byte Sections

This controls the shape of the shadow thrown by the object.
