Absolute World Position Node Problem...

guys hello
i am trying to use virtual textures, in the tutorial i found it uses the Absolute World Poisiton node. but in the tutorial it have 3 outputs ; XYZ, XY , Z. I need the Z one. but my absolute world position node only outputs one thing i don’t know what it is. i found something in google and tried to use mask node with RB but it is not working too. i am stuck wildly. if anyone have an idea, i will be so happy man… kind regards
