I tried this, striped my character down and then went to the mirror. First, looking in 'inventory' he is nude and 'equipped', then looking at the mirror he is wearing boxers and bald. Yep, bald.
Now I'm not running an 'RTX' GPU, I'm using an GTX 1080 Ti which does not have RTX. I'm wondering if this an RTX issue and not a game issue? Might be interesting to know what GPU's you folks are running and see if there might be something to this.
