Where is the WorldAlignedTexture node in the material editor for UEFN?

I would like to make my own material using the world aligned texture node, so I don’t have a stretching texture, instead it will just repeat over and over and not lose it’s quality, I noticed some of the base Fortnite rock assets have a world aligned texture but when I search for it in the material editor It does not show up like in the normal UE material editor. So… how do I do it with my own texture in UEFN just like them rocks in the modular mountain gallery?
