I have a plane (w/ texture and normal map) & a sphere (acting as a light source):
Normal map was created with Materialize by Bounding Box Software.
Why on earth does the one with the Normal Map look as though either the light is directional or that the plane is tilted?
Is this a problem with the principled shader? It is not, in fact, the principled shader; I just tested that while typing this.
So yeah, what is going on here and how do I fix it?
