i should start with that i am quite new to 3D and blender.

here is my problem:

while in edit mode i select the faces and assign a new material to those faces but material doesnt cover the whole face. i can see 2 horizontal lines on the vireframe which material is assigned between those 2 lines instead of whole face i can select . i cant select or edit those 2 horizontal lines. any help would be much appreciated. thanx in advance. .here is the screenshot of selected faces and applied material

    $\begingroup$ the Subdivision Surface modifier will virtually change the position of your edge loops, you can verify if you enable the modifier's On Cage option, therefore it will change how the material is displayed. You need to add edge loops if you want your material to stick to the position $\endgroup$

    $\begingroup$ I'd suggest unwrap the geometry properly an create a black and white mask, see the second answer of the linked Q&A. $\endgroup$

That said, as pointed out by Brockmann, maybe consider the other solution that would be to unwrap your object and create a b&w mask that would separate the glass from the label texture.

    $\begingroup$ you make me sad :'( I love edge loops, creases are just fake $\endgroup$

    $\begingroup$ you're right but in that case creases are not clean either, as you say creating a b&w mask is probably the best (but I was just answering to the why) $\endgroup$
