I am experiencing a lot of issues with the topology of a specific object I am modelling. Currently I have an issue with 'non-manifold vertices on it as shown by the screen shot below:
The mesh issue I have highlighted is found by operating
Select>Select all by Trait>non-manifold and checking only the 'vertices' option in options menu as pictured in the bottom left of my screenshot.
I would specifically like to be able to identify what the tool
Select all by Trait looks for when the 'vertices' option is selected, so I can better address my topology problem
I have read a fair bit about what can cause non-manifold geometry but simply non-manifold 'vertices' doesn't really mean a whole lot to me, can anyone shed any light
N.B: I have recalculated internal and external normals as well as 'merged by distance' multiple times which doesn't seem to do anything
