Based on FIA's safety car for the Formula 1 2021 season. Special thanks to @Isaac Chavira who's 2019 Blancpain Number Panels resource helped me to make the number panel for this livery.
To add this livery extract the zip file to the root of your Automobilista 2 install directory.
If this is the first livery you are adding for this car, simply rename 'mercedes_amg_gt3_new.xml' to 'mercedes_amg_gt3.xml' which you will find in Vehicles/Textures/CustomLiveries/Overides/mercedes_amg_gt3 then you are ready to play.
Otherwise, to add this livery to your existing collection, copy the lines of code below:
XML:
<LIVERY_OVERRIDE LIVERY="60" NAME="Safety Car #911" BASELIVERY="Default">
<PREVIEWIMAGE PATH="skins\crowdstrike_preview.dds" />
<TEXTURE NAME="BODY" PATH="skins\crowdstrike.dds" />
</LIVERY_OVERRIDE>
and add it to 'mercedes_amg_gt3.xml' in the Vehicles/Textures/CustomLiveries/Overides/mercedes_amg_gt3 folder right before the last line that is </USER_OVERRIDES>. This code will replace livery #60 for this car in the game.
Thank you.
