im getting some weird results.., very disappointing results actually.., with smoothing.., mayas new preview smooth.., which i would never use on my actual model and only on duplicates because it seems to distort the geometry.., does NOT give the same smooth results as the smooth command.., so in a way preview is only what it suggests.., a preview and not a final render.., a guestimate i would say

anyway.., im getting such tings happening as verts that seem to go the other way.., or just sort of shoot off somewhere.., i understand that the geometry must have similar construction.., with say a door and a door frame (weird example for smoothing but thats all that comes to mind atm) for them to butt up together., but whats these verts flying everywhere.
