It's hidden somewhere in the apron texture. Trying to pinpoint that location atm:
I'm actually planning to do the opposite with the jacket one, keep only the jacket xD
I'll try once I get the hostess one fixed.
EDIT: The shoe shadow thing... well. I guess the devs made a mistake since the "shadow" is pulling a part of the texture off the apron itself, not something you can remove without removing part of the apron.
Looks good, can u share ur apron texture file so i can see how it looks in game? I wanna see how bad/good looks if it changes part of the apron. At least the feet look clear .
