Documentation/Engine/Units/accessory interior data

The accessory_interior_data unit class is used to define the interior and its animations for the player's vehicle. Units of this type are usually defined in /def/vehicle/truck/<brand.model>/interior/*.sii, making heavy use of includes via:

• /def/vehicle/truck/<brand.model>/interior/animations.sui (animation-related attributes; animations_uk.sii for RHD vehicles in ETS2)
• /def/vehicle/truck/<brand.model>/interior/dashboard_color.sii (dashboard_color array attribute)
• /def/vehicle/truck/<brand.model>/interior/seat.sui (seat adjustment limits; seat_uk.sui for RHD vehicles in ETS2)

Attributes

Many common attributes are inherited from accessory_data.

Name	Type	Default Value	Description
model	string		Path to the model descriptor (.pmd) for the rigid interior model.
animated_model	string		Path to the model descriptor (.pmd) for the animated interior model.
collision	string		Path to the collision descriptor (.pmc). This is used for toy physics.
variant	token		Name of the variant to be used for the interior models and collision.
look	token		Name of the look to be used for the interior models.
ext_model	string		Path to the model descriptor (.pmd) for the exterior model (the interior visible from outside cameras).
ext_variant	token		Name of the variant to be used on the exterior model.
ext_look	token		Name of the look to be used on the exterior model.
animation attributes	string / float		There are currently nearly 70 interior animation attributes, plus _min and _max attributes for some with adjustable ranges. Interior animations are typically defined externally in animations.sui and included into the interior definition.
wiper_delay	array<float>		Each member defines a delay in seconds between wipe cycles for intermittent wipers. They should generally be in decreasing order because the last wiper mode is continuous. If empty then only continuous mode is available. Removed in 1.35.
wiper_duration_and_delay	array<float2>	(2.0, 0.0)	Each member defines the duration of the wipe cycle in seconds, and the delay between wipe cycles in seconds. They should generally be in decreasing order of delay, and decreasing order of speed. Added in 1.35.
blinker_delay	float	0.5	The length of half of the blinker cycle in seconds. The blinker is on for this length of time, and then off for this length of time, etc. Typically included via animations.sui.
show_chassis_rear	bool	false	It should be set true in interiors where you can see part of chassis or chassis accessory (eg ATS daycabs). It renders prebaked model of chassis and all its accessories in interior, so you might have issues with items that are mounted on chassis, but still have their own visualization in interior - you can see them twice and/or z-fighting. To be properly visible both inside and outside, either the accessory locator should be in chassis model ONLY, or it should be in interior AND in cabin cabin model both. Added in 1.44.
dashboard_path	string		Path to the UI definition for the dashboard display.
gps_path	string		Path to the UI definition for the GPS display.
use_mile_units	bool	false	When true, distances and speeds on the dashboard will use mile units instead of kilometers.
left_hand_traffic	bool	false	When true, the vehicle uses right-hand drive (UK) conventions.
backlight_with_lights	bool	true	When false, the dashboard backlight is always on with the ignition. Otherwise, the backlight is activated with the headlights as normal.
air_brake_safeguard	bool	false	When true, the parking brake is automatically applied when the supply air drops below a certain threshold (typical US behavior).
panel_intensity_min	float	0.01	The minimum backlight intensity.
panel_intensity_max	float	0.3	The maximum backlight intensity.
glass_panes	array<owner_ptr>		Each member points to the unit name of a glass_pane_data unit.
dashboard_color	array<float3>		An array of 16 colors which define the illumination color of dashboard and other dif.lum surfaces in the interior based on the tile they are UV mapped to. Typically included via dashboard_color.sui.
seat_left_limit	float	-0.15	Maximum distance the interior camera can be moved left. Typically included via seat.sui.
seat_right_limit	float	0.15	Maximum distance the interior camera can be moved right. Typically included via seat.sui.
seat_up_limit	float	0.15	Maximum distance the interior camera can be moved up. Typically included via seat.sui.
seat_down_limit	float	-0.15	Maximum distance the interior camera can be moved down. Typically included via seat.sui.
seat_front_limit	float	-0.1	Maximum distance the interior camera can be moved forward. Typically included via seat.sui.
seat_back_limit	float	0.2	Maximum distance the interior camera can be moved backward. Typically included via seat.sui.
sounds	array<string>		Each item assigns an FMOD event to a function, using the "sound_name|sound_path" format. Added in 1.39 Expected sound event names are: air_warning, blinker_off, blinker_on, noise, stick_blinker, stick_blinker_off, stick_engine_brake, stick_hazard_warning, stick_high_beam, stick_light_horn, stick_lights, stick_park_brake, stick_park_brake_off, stick_retarder, stick_wipers, weigh_green, weigh_red, window_click, window_move, wipers_down, and wipers_up.

Glass Panes and Wipers

Related units, glass_pane_data and wiper_data are defined within the same SiiNunit scope as accessory_interior_data, included via /def/vehicle/truck/<brand.model>/interior/glass.sui (or glass.dat in some legacy cases):

• glass_pane_data (Used to define surfaces for raindrop accumulation and wiper simulation)
• wiper_data (Used to define wipers that wipe drops from glass panes)

For example:

SiiNunit
{	// start of SiiNunit global scope

accessory_interior_data : something.brand.truck.interior
{	// start of accessory_interior_data unit

	// various attributes belonging to accessory_interior_data

	// each member refers to a unit included via glass.sui
	glass_panes[]: .brand.truck.pane.front
	glass_panes[]: .brand.truck.pane.close
	glass_panes[]: .brand.truck.pane.far
	// etc...

}	// end of accessory_interior_data scope

@include "glass.sui"	// file containing glass_pane_data and wiper_data units

}	// end of SiiNunit global scope
