Assetto Corsa Rally 0.4 update adds two cars, snow variants, and FFB/device support

We’ve got Assetto Corsa Rally 0.4 live, with new cars, expanded snow conditions, online/backend adjustments, and a broad set of handling, stage, audio, and camera fixes. The official notes are in this update post.

What changed

Cars

Added the Peugeot 306 Maxi Kit Car.
Added the Subaru Impreza S3 Group A.

Tracks

Added snow to Alsace and Wales.
Added snow support on off-road track materials.
Improved readability of road and trajectory in snowy conditions on all tracks.
Improved transitions between clear and fully snowy ground, and between dry and melting snow.
Improved consistency of snow effects across surfaces.
Improved snow particle effects on asphalt.

Physics

Implemented Fanatec FullForce and Logitech TrueForce, with a new in-game FFB parameter.
Improved compatibility for generic devices.
Added angular damping to small movable objects to reduce unrealistic spinning.
Further tuned tires on all surfaces, including changes to wet/snow tire-force behavior, snow deformation effects, dynamic masses/damping, gravel-tire snow grip, S-curve parameters, and load sensitivity.
Revised aerodynamic tuning for drag and lift.

Features

Added 3 new partners in the Rally Encyclopedia.
Added Partners functionality.
Leaderboards now have a dedicated partner endpoint.
Leaderboard entries now store the client version.
Player sessions now correctly set the client version.

Gameplay and UI

Updated pacenotes for Monte Carlo Bollene and Monte Carlo Sisteron.

Fixes

Fixed replay and gameplay camera clipping issues on the Hyundai i20 and Citroen Xsara WRC.
Fixed several audio issues, including turbo BOV cutoff timing, excessive hill reverb in cabin view, and random sound cutouts.
Fixed an incorrect pacenote call on Wales Hafren North 3/6.
Fixed stop marshals not guiding players to the stop point on select Monte-Carlo stages.
Fixed some respawn collisions around crowds on Monte-Carlo Bollene walls.
Fixed floating vegetation, minor text/translation issues, and other minor stage bugs.

For league ops, we should require everyone on 0.4, recheck wheel/FFB configs, and review any event formats that now use Alsace/Wales snow conditions.

cars

Bringing you two iconic 90's cars, snow to Alsace and Wales stages and a lengthy list of improvements and bug fixes that will take your Rallying experience to the next level.
[h1]Two New Cars:[/h1]
[h1]Peugeot 306 Maxi Kit Car[/h1]
The Peugeot 306 II Maxi Kit Car, made famous by drivers such as François Delecour and represented here in IKE Racing livery, homologated in 1997, is a remarkable example of late-90s rally engineering, designed predominantly for tarmac racing within the FIA’s 2-Litre World Rally Cup.

[h1]Subaru Impreza S3 Group A[/h1]
The Subaru Impreza S3 of 1993 driven by Colin McRae and which ignited the beginning of the Impreza’s rally legend marked Subaru’s serious entry into the World Rally Championship (WRC) with a car designed specifically for Group A regulations.

Two completely different philosophies: the 306 Maxi, with front-wheel drive and its high-revving naturally aspirated engine, is extremely effective on asphalt; the Impreza, with 4WD and a Boxer engine, is ready to attack snow and gravel.
[h1]Snow has arrived at Alsace and Wales[/h1]
We have applied our snowy weather technology to the Alsace and Wales rallies adding another element of challenge to these already challenging locations. You’ll really need to refrain from pushing too hard before you find yourself in a tricky spot.

fixes

- Fixed go-pro cameras in replays clipping with bodywork on ultra-wide resolutions in Hyundai i20
- Fixed gameplay cameras clipping with damaged bodywork in Citroen Xsara WRC
- Fix for turbo BOV sounds cutting off too early based on the drop in turbo pressure.
- Fix for too much “hill” reverberation coming through the cabin view.
- Fix for various sounds cutting out randomly.
- The usual “variety of tiny tweaks all over the place” statement ;)
- Fixed incorrect pacenote call on Wales Hafren North 3/6
- Fixed stop marshals at Monte-Carlo Bollene 7/8 and Monte-Carlo Sisteron 6/6 not guiding player to stop point
- Fixed some incorrect respawn collisions around crowd on Monte-Carlo Bollene walls
- Fixed minor text and translations issues
- Fixed floating vegetation bugs across all stages
- Fixed minor bugs across all stages

physics

- Implemented Fanatec FullForce and Logitech TrueForce, with new in-game FFB parameter to be tuned by users
- Improved generic devices compatibility. This enables more devices to work as expected.
[h2]PHYSICS:[/h2]
- Added angular damping to small movable objects to prevent unrealistic spinning
- Further tires tuning for all surfaces, in particular:
o The way wet conditions and snow affect tire forces has been modified; they no longer reduce cornering stiffness, and the S-shaped curve is effectively cut off when grip is saturated.
o In the case of snow, an additional experimental deformation component has been added to the slip angle, which increases the more suitable a tire is for snow. This simulates the tire actually gripping the underlying surface.
o The parameters related to the tire’s dynamic masses and damping have been fine-tuned for more consistent force delivery.
o The ability to grip on snow has been added to gravel tires, making them suitable for driving on snowy gravel roads.
o The parameters of the tire’s S-shaped curve have been adjusted based on test data.
o The load sensitivity parameters of some tires have been refined based on results from field tests.
- Revised aerodynamic tuning for both drag and lift forces

tracks

- Added support for the snow on the offroad track materials
- Improved road and trajectory readability in snowy conditions on all tracks
- Improved the transition between clear and fully snowy ground
- Improved the transition between dry and melting snow
- Improved the consistency of the snow effect between different surfaces
- Improved the snow on asphalt particle effects
