Does UVW unwrap reset to initial state if I modify mesh and weld some vertices?

[Anonymous]

If I apply UVW unwrap to a human character so it gets textured and then I modify the mesh, weld some vertices, add some, will the uvw keep its coordinates or will it reset to initial chaotic thing?

I mean should I 100% complete my mesh before applying uvw unwrap or can I work with it later?

I found the answer myself. Collapse the Unwrap UVW, it will bake the texture to the mesh, then edit your mesh, then just add the modifier again.
