Hi
I'm working through the cookie logo modeling videos and I've run into an edge loop problem. Here are the loops before I join the eye with the faces defining the bite:
But after I merge the vertices:
The edge loop across the eye now stops short and it's not possible to create horizontal edge loops across the two faces to the right. The vertical edge loops (one around the eye and the other along the bite) still appear, so it's something that has happened to the face where the vertices were joined and the one to the right. I've selected the vertices one by one and move them around to check that there aren't extra vertices hiding anywhere. I've also selected in x-ray and merged by distance, but no vertices are removed. I've merged by distance and increased the distance until the face just to the right of the edge loop disappears because the vertices on the left and right get merged. As far as I can tell, those faces are both quads. But Blender refuses to draw an edge loop across either of them. Have I missed something?
I started looking at this because I discovered that the faces I added while following the next section of the video (adding the faces in the gaps toward the top of the eye) also didn't allow edge loops. Again, there were no extra vertices that I could find. In the video I can see that those faces should allow edge loops because they appear as the mouse moves over the mesh. So it must be possible.
Hi Craig SSwitcher ,
That is obviously not what should happen, but I can't tell from the screenshots, what went wrong. Maybe I just need more coffee, but could you post a link to your .blend file (via Dropbox, Googledrive, or so) please? I am curious to know what's wrong with your Mesh that creates this behavior.
Here's 1 possible situation, where the Edge Loop would behave like it does in your case:
There are 3 Faces connected to 1 Edge. That 3rd Face might be very small, so not easy to spot, but still big enough to get missed by the Merge Distance Threshold.
Maybe it's something else...
Here's a link to a version that has the problem (just before merging the vertices).

I discovered that deleting the edge between the merged vertices and then recreating it and the faces results in working edge loops. That indicates there's something wrong with that edge, but I can't tell what. I looked for extra faces attached to it, but I could see any.
Hi Craig,
You have one big Face 'hiding' behind the small Faces, which you can easily see when enabling Face Normals (sorry, this is 4.4, where 'good' is no longer blue, but transparent, but in 4.3 or before, turning on Face Normals would also show you the issue):
Select it, Delete it and your Edge Loop will behave again.
