I downloaded a BRICK texture pack, which came with a diffuse image and several maps.
(This is all in eevee).
After experimenting a little, I decided to use the diffuse and displacement maps. I applied them onto a cylinder, starting with the diffuse image. It looked ok, sorta like this:
Then I proceeded to apply the displacement map, which gave me this:
I was satisfied with the look, but then I noticed this:
The texture on a certain PART (around 30% of the curved face) of the cylinder seems to have been "inverted" in the image above. All the bricks in this section clearly seem to "go into" the screen, rather than "come out" of it.
Here is my question: What is causing the issue, and how would I go about fixing it?
Also, if it is of any help, I noticed two jarring "lines" enclosing the inverted part of the cylinder (kinda like two boundaries), which, interestingly, had no shadows, meaning they aren't affected by the displacement map. One of the "lines" looked like this, (with the inverted part on the left, and the ok part to the right):
The other line is not in this shot. It's located a little to the side, and looks exactly the same.
