yea i have trouble getting metal to read as metal an not concrete tips?? I havent painted my spec map yet so its jus the diffuse on 60% Edit: Did a quick spec map an this is what it looks like so far
I believe he meant painted specular on your diffuse, not necessarily a spec map. you've very little highlights, if any. or perhaps they're just not strong enough... any chance we can get a peek at the texture flat? would be more helpful.
