Hello everybody!
Please help.

Shoud I apply a subsurf modificator before making unwrap of object? Because when I do it the process of unwrap getting very slowly (too much polygons ). But if dont then uv mesh is not the same like the object. Thank you for answers. Sorry for english )

Unwrap the low poly mesh. Just don’t apply the subdivision modifier unless you really have to.
