POM Looks weird

Hi, I’m using Lincoln Hughes’ POM materials which are very basic and pretty much just copied from the UE4 ones, but whenever I put my textures on (megascans in this case) I always get such weird behaviour, like it’s inside out or something

maybe i’m going wrong somewhere with linear/srgb but not sure what would cause this kind of thing?

Fixed this btw, it is the pixel depth offset not working with dynamic lighting. The un-pomm’d mesh is still casting a shadow on the updated pomm’d mesh
