I seem to recall a trait or feat that allows a half human race to appear human (as in naturally, without a disquise check). If I'm not imagining this and it does indeed exist, could someone kindly point me towards it.
The Pass for Human feat from the APG is what you are looking for. You get +10 to disguise and do not take a penalty for trying to disguise yourself as another race. In a largely populated area you can take 10. Still possible to see through it though.
