The Normal input takes in a normal map, which is used to provide significant physical detail to the surface by perturbing the "normal," or facing direction, of each individual pixel.

In the image above, both weapons are using the same Static Mesh. The lower one exhibits a highly detailed normal map, which provides additional detail, giving the illusion that the surface contains many more polygons than are actually being rendered. Typically, normal maps are often created from high-resolution modeling packages.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
