Prologue:
Minor issue that I do not seem to figure out, I've modeled room with some basic things that i've created from the scratch but now there is weird issue with wallpaper material.
Description:
All of the 3 walls are part of the same box object, they have same material and they have been uv mapped the same way on same scale yet the wall on the right displays on grey color instead of the white like the 2 others.
Steps taken:
I've deleted the wall with the issue, recreated it, uv mapped the whole thing again and ended up with the same results. Also went through recreating the material with same result. Checked the direction of normals.
Plea for help:
Any ideas what might cause this, still new to the cycles so would appreciate the insight to the problem so I can learn from it.
Thank you in advance.
