encode_light()

video::SColor encode_light	(	u16	light,
		u8	emissive_light
	)

Encodes light of a node. The result is not the final color, but a half-baked vertex color. You have to multiply the resulting color with the node's color.

Parameters

light	the first 8 bits are day light, the last 8 bits are night light
emissive_light	amount of light the surface emits, from 0 to LIGHT_SUN.
