Yeah, specular can't be baked but I could use a masked per vertex specular as they do on Shadow Gun which is pretty cheap, combine that with baked normal and it would look great on iOS. Any ideas if it's possible anyone???
@easterislandnick: I agree with Eric, it's not the goal to bake nmap light info. You should probably be able to use nmaps on iOS if you're not using an expensive shader, if you use specular + nmap it gets expensive for iOS. You will have to choose inbetween the two. I wouldn't go for that path, why do you need both?…
