I'm having issues with unwrapping a mesh with no seams. It should be a very easy process but I've been trying to solve this issue for a couple of hours.

image of the buggy unwrap. Green is highlighting the correct sections and Red highlights the incorrect UV in question

As you can see from the images above, it results in a horrible alignment. No double vertices, all transformations applied... The only parts that unwrap correctly are the furthest left faces and the bottom face. I have no idea why the rest of the UV won't align. Cube projection seems to get around this issue but it results in warped faces and unaccounted for UVs.

Did I unwrap this mesh correctly? If not, why isn't it unwrapping properly?

  • $\begingroup$ why have you separated the UVs? Maybe select all the mesh and unwrap once? $\endgroup$

  • $\begingroup$ It's all part of the same object, they were unwrapped together. $\endgroup$ Oct 20 at 6:25
  • $\begingroup$ it doesn't look like, the UVs are separated as we can see in the UV Editor, it explains why the texture doesn't match $\endgroup$

    $\begingroup$ maybe provide your blend file so we can check it out? $\endgroup$

    $\begingroup$ moonboots got is quicker ;) but as you can see - providing blend files help a lot to get quicker and more precise answers ;) $\endgroup$

The first part of the object is disconnected from the second part.You just need to join it. like this

As you can see in Edit mode the faces are separate, it separates the UVs when you unwrap:

You can quickly fix your problem if you create this edge and merge it with this vertex, then unwrap again:

Or choose another unwrap method, like Project From View.
