Is the tools for retopology the same as in 2.79b, or is there something better now?
in 2.8 you do have now a new tool in edit mode which is a little like retopo in 2.79
you add a plane remove all verts then with the Poly build tool you can add points like retopo
and depends on snapping mode it can retopo points on a model’s surface too.
see this intro
happy bl
That poly tool looks nice.
