I do not really understand why I need the combine XYZ note for the displacement in geo nodes. The tutorial says that it is used to limit the displacement just to the z coordinate. But why cant I just set the x and y in the multiply vector math node to 0. Isnt the multiply vector math node just multiplying the x and y with 0 and I just use the z value to add more or less displacement? Is there any issue with just using the vector math node without the combine XYZ?
Hi Luca SSadeModelling , you are correct, there are other ways to get the same result
