Changelog V2.3.0:
-Updated the mod for 1.39 patch (sorry for very late update, I just have not had time recently)
-Added support for openable windows and FMOD® sound system introduced in 1.37
-Made some minor upgrades for 4-series interior
-Fixed missing engine badge for DT12 18 440 Euro 3 engine
-Added more plastic/paint combinations for front fenders
-Added DXT5 compression for many uncompressed DDS-textures
-Lowered 4-series cabin by 7cm to its correct/more realistic position.
-Fixed issues with advanced coupling and collisions on the rear of the truck
-Fixed DX11 bugs with 5-series low bumpers
-Some other tiny changes I don't remember anymore
-Renamed a few locators with incorrect names. The truck might have missing parts after the update but you can reinstall them at upgrade shop. There might also be errors about missing parts in game log. You can remove them either by selling and repurchasing your truck, or by using "g_remove_missing_accessories 1" command, or just simply ignore them. The renamed locators are:
bumper -> f_bumper
bumpergrill -> g_bumper
f_plate -> f_plate_a
spoilerp -> wing_s
intakec -> c_intake
mirrorslots -> (removed because it was obsolete already)

Changelog  V2.2.4:
-Updated the mod for 1.35 patch
-Fixed errors with baked models
-Updated axle weight values
-Updated mirrors for head position-based FOV rendering (I should've done it for 1.31 already but forgot it at the time)
-Added more plastic/paint/chrome combinations for mirrors
-Added slots for mirrors (moved slots from "mirrorslots" locator to main mirrors)
-Color of headlight beam now depends on the type of headlamps installed on the truck (H4, H7 and Custom = Halogen / Streamline = Xenon)

This is an addon mod for RJL Scania T Mod and Scania R & Streamline.
For a several technical reasons, it does not add any new parts for those trucks. Instead, it adds new standalone 4-series truck which can be customized in the same way and as much as those two already existing truck mods.
So if you want to have 4-series, the first thing to do is visit at Scania truck dealer and buy the truck from there.
