[Question] Mesh Vertex with UVW are exploded about sharpgltf

[vpenades]

This is not a bug. The explanation is quite long, so I'll try to be as short as possible:

glTF is not an authoring format, it's a last mile format, that means that the vertex data is organized for fast rendering and not for easy editing. As a consequence, a vertex that has two adjacent polygons that share the same "vertex position" but have different UV coordinates is effectively duplicated. This is correct and there's no way to solve it from the glTF side.

Since glTF has become quite a standard, people is using it beyond its initial scope, and that's why you're having issues when importing it. I'm not an expert on blender, but the blender importer may have a checkbox to automatically weld vertices on import.

This is a briliant and clearest explanation!
With this context I see a way to work around for that subject.
You also right - blender has this import option.
Thank you so much!
