any suggestions how to replicate this Blender material node in Ue4?

oraeles77

have a look at the attached image...

so any idea what the name of the equivalent 'thing' is in UE4? In blender its refered to as 'extrapoliar clip' option.

I dont understand any of the complex node things in UE4. Im just trying to replicate something I made in Blender in Ue4 and nothing else.

so if you have the time to explain in simple english it would be a big help.

kind regards

olie.
