Recommendations

  • When basing your model on the original ones, add to your mod also ALL original /automat/ files used by it. The names of the files are generated as CityHash64 hash of theirs content so whenever we change the parameters of the material in any way, a different file will be used to store them and the original file might cease to exist if there is no other model utilizing the original parameters.
  • When modifying original models, always include ALL compoments of the model (pmg+pmd) instead of just those you changed. Otherwise you risk crash if we change the model.
  • As always when adding new objects to files which support multi-file approach (e.g. road_look.sii) it is HIGHLY RECOMMENDED to use suffix or prefix in the name to avoid conflicts with new objects we are adding in patches. Otherwise you might have to use the batch renaming functionality (see Batch renaming) to fix the conflicts when new patch appears.

How to convert map

  • Do rebuild (F8)
  • Save map

Changes

Vehicles data

Truck data

Transmission data

Transmission configurations got new attribute crawls. It represents count of crawl gears aka first N gears from ratios_forward array.

Note: Crawls attribute is used only for visual representation of crawl gears, si it doesn't not effect actual gear ratios in any way.

Trailer data

Steerable axles

For trailer to be using steerable axles several things has to be done:

1. Wheel locators inside trailer model that you want to use as steerable has to be named wheel_f_X (where X is number of the steerable wheel and starts with 0 on the front most left steerable wheel)

2. You have to define front wheel for the trailer. For example define file def/vehicle/t_wheel/steerable.sii with this content:

SiiNunit
{
accessory_wheel_data : steerable.fwheel
{
	model: "/vehicle/wheel/overweight/245_70_r17_5.pmd"
}
}

3. As last your trailer unit configuration files (inside folder def/vehicle/trailer/) has to use front wheel accessory. Example trailer configuration file:

trailer : trailer.trailer_name.cargo_name
{
	accessories[]: .trailer_name.cargo_name.tchassis
	accessories[]: .trailer_name.cargo_name.trwheel0
	accessories[]: .trailer_name.cargo_name.trwheel1
	accessories[]: .trailer_name.cargo_name.trwheel2
	accessories[]: .trailer_name.cargo_name.cargo
}
vehicle_accessory:.trailer_name.cargo_name.tchassis
{
    	data_path: "/def/vehicle/trailer/trailer_name/chassis.sii"  # link to chassis definition file
}
vehicle_wheel_accessory: .trailer_name.cargo_name.trwheel0
{
	offset: 0
    	data_path: "/def/vehicle/t_wheel/overweight.sii"            # link to normal trailer wheel definition file
}
vehicle_wheel_accessory: .trailer_name.cargo_name.trwheel1
{
	offset: 2
    	data_path: "/def/vehicle/t_wheel/overweight.sii"
}
vehicle_wheel_accessory: .trailer_name.cargo_name.trwheel2          # definition of steerable axle!
{
	offset: 0                                                   # note that offset again starts from zero.
    	data_path: "/def/vehicle/t_wheel/steerable.sii"             # link to newly created front wheel definition file from step 2.
}
vehicle_accessory: .trailer_name.cargo_name.cargo
{
    	data_path: "/def/vehicle/trailer/trailer_name/cargo.sii"    # link to cargo definition file
}
