Another problem: When click Tab as usual to select the vertices, my entire model isn't highlighted, only the vertices of a single split group of the model are selected.
I think a plugin that reprojects normals already exists, but it's not a very fast workflow either. Ideally a plugin would go through a hard-edged mesh, group vertices by similar direction, discard groups where vertices are closer than a certain threshold (indicating they are probably part of a chamfer), merge all vertices…
@PolyHertz Welded UV vertices could be defined as a single UV vertex sharing two or more geometry vertices, so a tool can be created to process them. Except for speed, there is no need for a build in method to do it, it can be scripted. Although I am not thinking which other tools would support it, the result is the same…
Have you welded the border vertices ? If not, make sure your border vertices are identically skinned. It's possible that there is a few units difference, and this is enough to create a physical break in the model.
NVM, it appears that it's because I didn't perfectly alight those UV seams to the perfect vertical. It's really slightly off from a perfect vertical and it changed the whole thing.
Add Vertices to the 'Align Line' and then Snap the Vertices of the other line one by one...might be possible to automate, but I am too lazy to write something now... :D
Maybe it's possible with bpy. but i don't know if you can store custom data like that on vertices with python. It doesn't even need to work procedurally, it just needs to be one button for lock and another button for snap. each vertex on the lp would need to hold a unique identifier for their respective hp vertex so they…
