I'm attempting to create a simple resized cube with a noise texture on all six sides. The cube is just a default cube that is scaled down in the Z axis so it appears very short.
No matter what version of Blender I use, the top of the cube works completely fine, showing the noise texture as usual, but the sides of the cube appear like this (this screenshot is from Blender 2.7, but my main computer does the exact same on Blender 2.8):
Things I've already tried: - I've made sure that the UV unwrap is correctly scaled to the scale and rotation.
I've tried converting the noise texture to a bump map and a normal map, it doesn't change the result.
I've tried two different versions of Blender and 2 different machines
While I'm sure there is something very simple going on here that I'm missing because I'm inexperienced, I'm stuck and can't find any information on my errors.
Any help is appreciated.
