	== Configuration of texture unit 3 ==		== Configuration of texture unit 3 ==
	The configuration block for texture unit 3 seems to be vastly different from the other texture units. Instead, registers 0x00A8 through 0x00B7 are used to configure procedural texturing features.		The configuration block for texture unit 3 seems to be vastly different from the other texture units. Instead, registers 0x00A8 through 0x00B7 are used to configure [[GPU/Procedural_Texture_Generation\|procedural texturing]] features.
