Edge loops Vs crease? I know its the kind of question that being asked a lot.
and its seems the majority is in favor.
of using edge loops when subsurfing a mesh.
because:
-crease creates unrealistic edges.
-edge loops are allowing more control on the shape of the edge.
-crease can create shading issues when object being deformed.
-creases can not be exported
so here is my question:
I'm learning how to do Hard surface modeling.
my model are not suppose to be deformed ( tough they are intended to be exploded later
up until today my favorite workflow in those situations.
is to
-add sub surf modifier,
-use the crease to keep the sharp edges were i want to.
-add bevel modifier below the subsurf modifier
in order to bevel those edges.
can i expect any issues of shading with this method?
and if so what kind of issues should i expect?
Subdivision surface modifier creates new faces between the existing ones and uses the material from adjacent faces to fill in the new ones.  So if you're assigning materials to faces, you can run into issues where subdivision pulls the material seam away from where you want it.
You see this when there are faces of different lengths:
