optiloops
Optiloops is a blender 3d addon for optimizing topology.
It goes through loops of the mesh and removes loops selectively by several constraints:
-max/min face angle present on the loop
keep by:
-seams
-bevel
-crease
-influencing loops essentials for subsurf shape (offset edges)
now repeatable with shift R doing sel result before (selecting remaining geo when dissolve on)
