Weird behaviour when assigning material to specific faces I'm following a guitar tutorial, and I created a material for the sides of the guitar. I assigned it to the sides, but in rendered view I get a band of the other material above and below the side material.



Any Idea why this is happening? Any help is appreciated!

EDIT: .blend file
The subsurf modifier is smoothing the edges which allowed the above material to bleed out to the sides.

Add two loop cuts to the sides to fix it. (shortcut ctrl+R, then sroll up once)
