HOW TO: Enable reefer sounds for your trailer mod with Sound Fixes Pack

[Drive Safely]

Note: Reefer sounds aren't currently a standard feature in the game so this is a workaround we can pioneer for now, until it's supported in the game in the future.
If this idea proves popular, it may signal to SCS Software to support such a feature in the game one day.

Do you have a reefer trailer mod and want reefer sounds for it?

The Sound Fixes Pack has a reefer sound bank added to it that modders can reference.
First I will explain the quirks of the mod.

Important quirks to note

1. The refrigerated trailer will beep and its engine will startup after coupling the trailer.
2. The reefer will continue to run as you drive and you can hear the hum of it from the truck interior.
3. The mod relies on the trailer tire sound to carry the reefer sound.
4. The sound event will stop after decoupling the trailer.
   ⠀
5. For any owned or unsupported reefer trailer, there is a workaround built in to the Sound Fixes Pack to enable the reefer sound.
   The reefer startup sound effect is not supported with the workaround option.
   ⠀
6. Some roads may not be supporting trailer tire sounds, hence why the reefer sound might not work there.
   If this happens, driving offroad into the grass or gravel usually gets the reefer sound loop working again successfully.

Regarding what the refrigerated trailer sound can be confirmed to work with:

✓ Freight Market: Confirmed to work.
✓ External Contracts: Confirmed to work.
✓ Quick Jobs: Can work, but you need to disconnect and reconnect the trailer to start the cycle.
- Ownable Trailers: Confirmed to work if there is the applicable code in the definition file. If it's not present you can use the workaround option, however the workaround option does not include the reefer startup sound effect.

Owned trailer workaround

To use the workaround option properly:

1. Go into the Audio settings.
2. In the voice navigation menu, select "~ Function - Force enable reefer sound".
3. Click the Preview button.
4. Reselect your desired voice navigation option OR uncheck the voice navigation.

Note that the reefer beep & startup sound is not available with the workaround option.
To stop the reefer sound with the workaround option, detaching the trailer will stop the sound in most cases. If not, restarting the game is the only way.

How do I add this sound to my trailer mod?

First make sure you have Sound Fixes Pack enabled. Then in the definition file for your trailer chassis where the mass and brace animations are determined, you need to add these two lines:

Code: Select all

	trailer_brace_up_sound: "/sound_fixes_pack/trailer/reefer_up.soundref"
	trailer_brace_down_sound: "/sound_fixes_pack/trailer/reefer_down.soundref"

Here is an example of how it looks for an SCS trailer file:

Code: Select all

SiiNunit
{
accessory_chassis_data : .chassis
{
	detail_model: "/vehicle/trailer/scs_box/ch_45_r.pmd"
	model: "/vehicle/trailer/scs_box/ch_45_r_lod0.pmd"
	lods[]: "/vehicle/trailer/scs_box/ch_45_r_lod1.pmd"
	lods[]: "/vehicle/trailer/scs_box/ch_45_r_lod2.pmd"
	collision: "/vehicle/trailer/scs_box/ch_45_r.pmc"
	variant: reefer
	look: default

	trailer_brace_model: "/vehicle/trailer_owned/scs_box/chassis/trailer_brace.pmd"
	trailer_brace_anim: "/vehicle/trailer_owned/scs_box/chassis/trailer_brace.pma"
	
	trailer_brace_up_sound: "/sound_fixes_pack/trailer/reefer_up.soundref"
	trailer_brace_down_sound: "/sound_fixes_pack/trailer/reefer_down.soundref"

	extended_shadow_texture: "/vehicle/trailer_owned/scs_box/shadow_ch_45_r.tobj"
	extended_shadow_intensity: 1.45
	extended_shadow_fadeout_start: 10
	extended_shadow_fadeout_length: 0

	ui_shadow: "/vehicle/trailer_owned/scs_box/chassis/shadow_ch_45_r.pmd"

	trailer_mass: 6722.2	# 14820 lbs

	residual_travel[]: 0.12
	residual_travel[]: 0.12
}
}

These chassis files are usually found under the def/vehicle/trailer folder structure of a reefer trailer mod.

For owned trailers, they would typically be under the def/vehicle/trailer_owned folder structure of a reefer trailer mod.

Reefer unit sound variations (only for Euro Truck Simulator 2)

Reefer unit sound variation for the Schmitz Cooling Unit. To use this instead of the default, you can apply the following line of code for trailer_brace_up_sound:

Code: Select all

	trailer_brace_up_sound: "/sound_fixes_pack/trailer/schmitz_cargobull/reefer_up.soundref"

Reefer unit sound variation for the Carrier Vector Refrigeration Unit. To use this instead of the default, you can apply the following line of code for trailer_brace_up_sound:

Code: Select all

	trailer_brace_up_sound: "/sound_fixes_pack/trailer/carrier/reefer_up.soundref"

Reefer unit sound variation for the Thermo King A-400 Refrigeration Unit. To use this instead of the default, you can apply the following line of code for trailer_brace_up_sound:

Code: Select all

	trailer_brace_up_sound: "/sound_fixes_pack/trailer/thermo_king/reefer_up_a_400.soundref"

Reefer unit sound variations for AI traffic trailers in Euro Truck Simulator 2

For traffic trailer mods, you can apply a reefer unit sound to an AI traffic reefer trailer if you want to within the SUI of the traffic trailer (the file where traffic_trailer is in the start of the file contents).

AI traffic - default reefer unit:

Code: Select all

@include "/def/vehicle/trailer/sound_fixes_pack/reefer_default.sui"

AI traffic - Thermo King A-400:

Code: Select all

@include "/def/vehicle/trailer/sound_fixes_pack/reefer_thermo_king_a_400.sui"

AI traffic - Schmitz Cargobull SCU:

Code: Select all

@include "/def/vehicle/trailer/sound_fixes_pack/reefer_schmitz_cargobull_scu.sui"

What sounds are included?

The sound includes the trailer brace sounds, then right afterwards you will hear the startup of the reefer engine. The reefer engine will then continue to play in a sound loop.
The reefer engine will sound the loudest when you are close to the trailer of course. You will be able to hear the hum of it inside the truck also.

Because modders can now specify whether a trailer can have a custom trailer brace sound, this means it's possible to have this sound for only reefer trailers, which is quite a treat when you do haul a reefer trailer in the game.

What even is a reefer trailer?

Reefer is short for "refrigerated". These trailers are designed to maintain a specific temperature for its cargo. It is commonly used for perishable cargo, such as fruit and vegetables.
It is powered by its own engine to keep the temperature consistent. That is where its sound comes from.

[Drive Safely]

@djmistaxclusive - If the code for the trailer brace sound isn't present you can just add the two lines shown in the first post

[djmistaxclusive]

How to add to krone dlc? please help. I`m amateur.

[Drive Safely]

@kuaczi223 - Welcome! I haven't purchased the Krone DLC (yet), but the files for the Krone reefer trailer should be somewhere in def/vehicle/trailer.
It will probably include "reefer" in the filename or it has it in the variant attribute for the chassis file.

To extract the DLC file you could use the SCS Extractor: https://modding.scssoft.com/wiki/Docume ... _Extractor

[kuaczi223]

there is no refeer file, but a cooliner file.

[Drive Safely]

@kuaczi223 - I searched up "Krone cool liner trailer" and I think it's safe to assume it is a reefer trailer type. You can edit that file

do i need to edit dlc and pack in scs? After pasting the data from the trailer to the mod, the krone dlc does not work. I can send you files, if that's not a problem, maybe you can do something about it. I'm sorry for the trouble.

[Drive Safely]

@kuaczi223 - Yes, but you only need to include the folders and files that have been changed. And the packed scs file goes to the mod folder where you enable it as a mod in the Mod Manager.

The original DLC in its Steam folder location you just keep unmodified.
