Heightmaps | Advanced PBR Explained in Unreal Engine |

In this video we will learn advanced Physically Based Rendering concepts necessary for getting proper results when using PBR in Unreal Engine. We will cover heightmaps, which are used to get extra detail in our meshes but without the extra geometry and the associated performance cost. We will see how to use Bump Offset, Parallax Occlusion Mapping and Displacement (World Position Offset) in Unreal Engine.

how to scale / tile the texture itself... because I cant use texture coordiante, uv node is being used by paralax occlusion mapping.

You can use the UVs (V2) pin, in the same way that you would use the UVs input in the texture samplers:

There is a caveat, as is, you cannot use rotation in the UVs. You need to modify the POM function for it to account for UV rotation, I may make a video if enough people are interested.
