WorldNormal question

Hi All

Im following a tutorial on Displacement maps, this is the video:
This is for UDK but works for Unreal 4, except for one element I cant understand.
Its asking in the video for me to insert a WorldNormal parameter, which just has one in, one out.
However I cant find this in unreal 4. There is WorldAlignedNormal, but that brings up a box with many ins and out, and ive tried and I cannot get that to work

If someone could explain how I get the WorldNormal simply parameter up, they can choose 2 free packs from the Arteria3d website

Thankyou in advance


Could anyone please help here?
