Real 16:10 gameplay

[Gniarf]

Not sure about what you mean by "they always look like in 4:3".
1-To "push the weapon forward" you can either try
1.1-opening every .CWeapon file and patching by hand o.Pos (very lame, but easy)
1.2-looking at function CWeapon:ClientTick2(delta) (in CWeapon.lua) and adjust the term(s) in z in ENTITY.SetPosAndRotRelativeTo (ok if 1.3 fails)
1.3-Look at the various self.Pos:Interpolate(self.PosZoom.... I suspect the core of the problem might be here.
2-I you want to stretch (actually schrink) the model in one direction (ie: make it less wide), well, honestly, go flak yourself 455 holes in hell, 'coz if I could stretch in only one direction, that would have spared me a whole lot of trouble in the symetry thread...I think.
