[Solved] Seam that won't delete

18 posts in this topic

Hello friends! I'm having this issue of not being able to delete seams on my mesh... And I never even intentionally placed them. Do you see that skinny purple strip? I don't want that to be its own island, but I can't get it to disappear using ctl left click on the seam

Hmmm I clicked on "hood_01", which is the hood retopo where I'm having the issue, and the seam still won't delete... :o

Check if the island is not on a different UV-Set.

so it turns out it's not a seam issue, it's something else entirely. If (1) I delete a face, (2) add it back in, it becomes a different color than the retopo around it. But if I (3) make that retopo layer invisible, the who thing disappears.. What's going on? :P

Help some other poor sod with an explanation.

Well I don't know WHY it was happening, but I have a solution. If you select all faces on that retopo mesh with the "select all faces of this layer" button within the retopo menu, clone it with the "clone" tool on the left panel, and hit enter, you will be given a copy that behaves just how it should.

Good show! Can you delete the old part (so as not to have baking problems)?

Yes definitely. Just delete the entire old mesh, and keep the new cloned layer. :)  If you have this issue, you should be good to go!

I make my models in 3D-Coat, so I have never encountered the issue.^_^

That's a very convoluted solution. Have you chcecked for multiple UV sets in your scene, like I suggested?

My suggestion worked temporarily, so I tried moving all uvs to one and that fixed it... I think..

Ok. So it's 2017 and I haven't seen an answer for this. I do have a sure fire work around but it can get tedious if the issue persists.

-Export messed up mesh portion from 3D Coat.

-Open .OBJ in preferred 3D program other than 3D Coat.

-Clear seams, edge smoothing and face smoothing.

-Export selected mesh without edge, normal or material information.

-Import back to 3D Coat.

 

The mesh should be one united piece again.

NOTE: it might be beneficial to just do all the modeling changes you want before starting with the initial export in the first step.

Save your UVing for last when you are happy with the mesh, as usual.

Hope this helps someone. If anyone figures out the actual problem, please post it.

I found a fix. Should anyone come across this problem, this how to fix it: select the Marks Seams, Hit Spacebar, and select Unify UV in the Spacebar menu. Hope this helps.
