Pink textures for passengers and crew when using Pilot's Dash-7

[Dravman]

Hello everyone

No issue at all with textures when using default liveries for Pilot's Dash-7
But if I use a third party texture, I'm getting those pink textures on Crew and Passengers.

Is it something to fix in aircraft.cfg file or in other file. if yes, so how to fix that ?

Thank you

Cheers - Ciao
