Using BBLauncher 16.12 with the latest build of ShadPS4, I have not run into any serious problems with the character generator. All textures are working great.
The only (minor) problem that comes up is that occasionally the preview portraits fail to load, but if you click into those to switch to a new hairstyle/color/new number on a slider/etc and go back to the main screen, you'll see how the modification looks on the main character model.
I'd buy an official PC port of Bloodborne in a heartbeat. Disappointing that it's unlikely we'll get any port at all from Sony in the indefinite future now.
