Might seem like a noobie question but I can't seem to figure it out. What would be the most effective way to unwrap a simple cube mesh in order to replicate UV unwrap that looks like this, where an image texture extends past the edges?

Is there a simple way to do it? enter image description here

enter image description here

I've added seams to my mesh as such, but it seems that this is still not properly allowing the image to "wrap around" the edges. I'd rather not have to move the UV islands all manually. is there something I did wrong?

Making the seams on the back-side of the cube instead of the front is important, so I made sure to do that.

enter image description here

After U > Unwrap, the UV map that is generated looks like this.

  • $\begingroup$ You did it the other way round! that's way it does not align. The face you mark your seams around is the one facing the wall, not the one you want to look at $\endgroup$

  • $\begingroup$ @JiříHonzák yup! Cube project. I'd rather mark the seams than move the islands each time. $\endgroup$

  • $\begingroup$ You cannot use cube project when marking seams! If you want to mark the seams by hand you should use unwrap $\endgroup$

In this case simple cube projection shoud be ok, you might need to move the UV islands in UV editing in order to make the image seamless. Or you can mark seams by hand like this (select edges -> right click -> mark seam):

After unwrap you get exactly what you want:

You need to create seams at the corners and at the back of your cube to and unwrap that way, I'd set up the UVs like this: enter image description here

Make sure you're applying the scale before you do the unwrap so the uvs turn out right.

Bonus view of the back to help you understand where I placed my seams! enter image description here

  • $\begingroup$ Can you post your UV layout? Bit difficult to understand whats going on at the moment :) Just from the look of things you look like you marked the seam on the wrong side of the cube! $\endgroup$

If you unwrap with the default mode, here is what you'll get:

To make the UV square, enable the Snap to Vertex option and move the vertices until you have this:

If the sides are too deformed, subdivide a bit:
