second shot is more clear.
I said to use an ingame shot cuz when aldo showed it for the first time the coders said that this problem is a modelview only problem and is not happening in game.
Pick that shot (and possibly others too, since it isn't completely clear if it doesn't depend by the absence of smoothgroups) and post em in the scp forum
There's another weird smoothing problem I had with the rounded surfaces (like tie's sphere) when converting with pcs and using specular in game, that makes you see the borders of the polys, I don't even know if it has been solved honestly, maybe I should check and take a shot too.
