metalliandy's sharp from uv isles doesn't seems to work with latest blender.What are you blender people using to harden edges to uv islands for nmaps ?
In UV editor go to UVs -> Seams from Islands to make sure all your UV islands have corresponding seams on the 3d model. Then on the model itself, select a seam, press shift+g (select similar) and pick the Seams option. This will select all of your seams. Now simply mark them all as sharp. (ctrl+e -> mark sharp).
Thanks man ! that was easy my latest blender seems to have a Make sharp check option when i use UVs -> Seams from Islands so i don't need to make the last step.
