broken: One then just has to be careful, maybe in some occasions people still don’t want this automatic Set Smooth/CTRL-N business. So it should be a toggle. I’ll give it a try in iblender, look how it feels, and then come back
I’d say that for the 0.001% of the time where someone does want a solid shaded subsurf and an ugly black line on their model, it’s not too difficult to select those faces and press ‘set solid’, and manually flip the normals how they want (as we now do for the other 99.999% of the time, but in the opposite).
Of course this is assuming that such a feature wouldn’t overwrite the entire mesh, it should just make newly created geometry smooth and with correctly facing normals, leaving any other smooth or weird normalled bits on other parts of the mesh as they were.
Wow. I must have a special version of Blender or something, because for me it’s just (literally) 1-2-3. I mean it takes… opens Blender… 3 seconds at the most. I guess it may be a nice feature, but you should definately be ably to flip back. I, personally, like to model in solid mode, not smooth. It just makes sure that ALL the normals are the way I want them.
Maybe, though, this would be a nice option, possible in the next version?
