HELP! Setting up Tessellation

[vanuatuian]

Hey Guys

Any help would be greatly appreciated.
I’m really new to this and i cant figure out how to get these two extra notes i need: Tessellation Multiplier node and Distance param node.
so this is what iv got so far. I right click and type in what i need and i cant find it.

and here is what i need to have to get my Tessellation to work according to the Unreal wiki but i cant find them.

Hi,
it’s just Parameter, add constant quickly by holding ‘1’ and LMB anywhere and then RMB on it and choose “Convert to parameter” and call it how you like: “Height”, “Distance”, whatever. The same with “Tesselation Multiplier”

In case of the picture, they use a scalar parameter
