On a left side there’s a greyscale image I used as a source, on a right side there’s the normal map generated in Photoshop CC with a default settings.
How do I get rid of these horizontal and vertical lines every other pixel? It looks really, really bad when put into the UE, almost as if there would be some wireframe one it.
I seen someone suggesting to use 16 bit instead of 8, but it doesn’t make any difference as far as I see. I also tried changing settings in a filter window, but they don’t seem to affect these lines.
Any ideas how do I generate a smooth normal map with Photoshop?
