Documentation/Engine/Units/accessory paint job data

The accessory_paint_job_data unit is used to define paint jobs for trucks and trailers (as of ETS2 1.25/ATS 1.4).

Usage

Airbrush

In the airbrush mode, the RGB of paint_job_mask is blended with the base color, using the alpha channel as the blend factor. This mode is active when the attribute airbrush is true.

Colormask

In the colormask mode, each of paint_job_mask's color channels (RGB) acts as a mask for a color being blended over the base texture. They are applied in the order blue, green, and red. So the red channel has the highest “priority”, followed by green and then blue.

TIP: Texture compression can lead to some minor aliasing at sharp boundaries between the mask channels. To avoid colors ‘bleeding through’ at these boundaries, try blending some of the lower-priority channel ‘under’ the higher-priority channel along their shared boundary. For example, at a sharp boundary between the red (255, 0, 0) and green (0, 255, 0) channels, a thin line of the base color may be visible. This can be mitigated by coloring the edge of the

Attributes

Many common attributes are inherited from accessory_data.

Name	Type	Required/Optional	Modes	Description
mask_r_color	float3	optional	colormask	Defines the default color applied to each channel of the color mask.
mask_g_color
mask_b_color
base_color	float3	required	all	Defines the default color of the paint job.
mask_r_locked	bool	optional	colormask	When false, the player may change each channel's color via the color picker.
mask_g_locked
mask_b_locked
base_color_locked	bool	required	all	When false, the player may change the base color via the color picker.
flip_color_locked	bool	optional	flipflake	When false, the player may change the flip color via the color picker.
flake_color_locked	bool	optional	flipflake	When false, the player may change the flake color via the color picker.
flip_color	float3	optional	flipflake
flip_strength	float	optional	flipflake
flake_color	float3	optional	flipflake
flake_uvscale	float	optional	flipflake
flake_density	float	optional	flipflake
flake_shininess	float	optional	flipflake
flake_clearcoat_rolloff	float	optional	flipflake
flake_noise	string	optional	flipflake	Path to the flipflake texture.
flipflake	bool	optional		When true, flipflake (metallic/pearlescent) behavior and attributes are enabled. Cannot be used with colormask.
airbrush	bool	optional		When true, airbrush behavior and attributes are enabled. Cannot be used with colormask.
alternate_uvset	bool	optional	all	When true, the resulting material will have the altuv flavor. This triggers usage of the alternate UV layout, if configured.
stock	bool	required	all	Defaults to true. This was previously used to mark paintjobs available when purchasing a truck when true, and only available from the upgrade shop when false. Currently must be set to false to avoid undesirable behavior.
paint_job_mask	string	optional	colormask, airbrush	Defines the path to the texture resource (.tobj) to be used for color masking (colormask) or for blending (airbrush).
base_texture	string	optional	all	Can be used to override the base texture of the truckpaint material. Requires that all truckpaint materials on the vehicle use the same base texture in the first place.
