Hello and welcome,
we've updated our Modding Guide for beginners on how to create custom repaints for vehicles. You'll find it to be compatible with Fernbus Simulator and Tourist Bus Simulator.
As the guide is quite detailed and long, you can downlaod it as a PDF here: TML-Studios Community / Filebase / Fernbus Coach Simulator / Official Repaint Templates
Here you will also find the updated MAN Lion's Coach repaint template shown in the PDF.
You can also find this new guide in the Steam Workshop: Fernbus Simulator > Guides > Guides von TML Studios > Modding Guide: How to create custom repaints for vehicles
