Sometimes I create an edge loop and then have to recalculate the incorrect toplogo angle after bevel or Multip cut, then have to recalculate the Edge Flow. So sometimes I use the Crease tool again. However, I found out that Crease does not support when exporting to other software. I want to ask those in the industry…
Creases are very useful working with subdivision modeling in early stages, i use them in lvl-0 or lvl-1 of detail. But later, when i "collapse" modifiers or i subdivide, i use edge loop support.
