Well someone on Twitter make a print, so here is! Mack.anthem folder was added in /def/vehicle/truck!
And it was the same thing that happened in the LoneStar folder when his folder was added in 1.36! There was only the Utah bee file in inside.
I made one delivery on my International. Pleased with the changes, although it is obviously beta and lots of work still needed. With an openable window, I would expect a lean-out camera to either be blocked when window is closed or force window to open with a reasonable delay before the camera moves outside. Also, a walk-around feature must be expanded. It is now shown that the game engine can handle it, so make it possible everywhere! You could limit the distance player could walk away from the truck, but it would be so fun to be able to walk back and attach cables manually, pull trailer legs up/down manually, even check space when parking instead of using external free-camera. Later replace delivery icons on entrances with offices within companies' prefabs. Would be blast!
