I am very new to Unreal and am having issues setting up my first landscape. I have tried googling this issue extensively and not found anything that relates - I apologise if this is something simple which has already been covered hundreds of times!
I can apply most textures to my landscape material (baseColour, roughness etc) and verify that they appear as expected in the viewport, but as soon as I add the normal map everything is covered in deep shadows and large chequered squares - much bigger than the individual texture tiles. If I leave the camera stationary the light slowly gets brighter over time, until I change anything or move the camera - then it instantly goes dark and slowly gets brighter again...
I have tried rebuilding the lighting, and switching DXT5 normals on and off in the project settings and nothing is making a difference.
I'm sure the fix won't be too complicated, but I'm going a bit mad trying to work it out on my own!
