iRACING UI:
AI Racing in Hosted Racing
A new feature has been added to Hosted Racing: the ability to utilize AI Racing and AI Opponent Rosters!
– – Hosted Sessions now include the ability to add an AI Opponent Roster to the Hosted Session. This allows the Session Host to bring in AI Opponents to fill-in unclaimed entry spots for the Hosted Session, ensuring a full racing grid, and allows for multiplayer AI Racing. This feature may also be used in Hosted League Sessions!
– – You can see if a Hosted Session is utilizing an AI Opponent Roster by an “AI” icon on the Session, or by checking the Summary screen for the Session. During the Session and in the Race Results, AI Drivers are indicated with an [AI] tag, or a robot icon.
– – While a Hosted Session is running with AI Drivers, the AI Drivers are processed on the Session Host’s machine. This means the AI Drivers will share any connectivity issues experienced by the Session Host. This also means if the Session Host disconnects, the AI Drivers will disappear from the event until the Session Host rejoins.
Some notes about setting up AI Hosted Sessions:
– – Only Hosted Sessions that utilize AI-enabled content may enable AI Opponent Rosters.
– – Team events may not be created.
– – Heat Racing Events may not be created.
– – The “Avoid Me” option is available in the form of “Avoid Players”. This has also been updated in offline AI Racing.
– – The Session host may edit a pending Hosted Session that includes an AI Opponent Roster.
Some notes about AI Opponent Rosters:
– – An AI Opponent Roster of any size and makeup can be used for a Hosted Race.
– – AI Hosted Sessions can utilize an existing AI Opponent Roster, or one can be generated while the Hosted Session is being created.
– – When an AI Opponent Roster is enabled when creating a Hosted Session, the default number of AI Opponents to include in the Session is equal to half the size of the selected Opponent Roster, or half the amount of Grid Stalls, whichever is smaller.
Some notes about Registering the AI Opponents for the Session:
– – After Registering for their Session and before the Session Host clicks to Join their Session, the Session Host can select the amount of AI Opponents that should join with them when they click their Join button via a slider next to the Join button. This could be any number from zero to the full AI Opponent Roster! However, keep in mind that AI Opponents fill grid stalls, just like human players, and once they are Registered, that grid stall is filled, and they can not be removed. However, the Session Host can exit their Session and re-join, increasing the number of AI Opponents to register with them before the Race starts.
Sorry, AI Drivers may not have Protests filed against them!

Dirt Racing
The formula for determining the grip levels of a dirt track based on water content has been updated. Dry slick is now a bit more grippy.
Dirt Oval Racing
The dynamic track data for Dirt Ovals has been improved to prevent an uncharacteristic washboard-effect that could occur on straights.

– – – – These changes should result in AI Vehicles having slightly increased tire grip.
Fixed an issue where disqualified AI Drivers would remain on the grid for eternity. They now remove their vehicles from the track, and go on to live prosperous lives.
Damage Modeling
The “No Damage” mode has been updated for improved interaction with collisions.
– – This damage mode now allows the simulation to execute full vehicle damage, allowing the physics to perform accurately for more realistic collisions. Then, after the crash has settled and a very short duration, all vehicle damage is immediately repaired. This alleviates impossible physics behaviors that could occur under the previous system which utilized some indestructible and non-pliable objects. These changes should make vehicle collisions more realistic and predictable, even when racing with damage disabled.
– – This system operates when using either the original damage model or the New Damage Model.
A new system message is now displayed when the Simulator is using any damage model other than normal damage.
Fixed a long-standing bug where player wheels would sometimes pass through opponent cars and/or their wheels.
– – This fix should significantly improve the consistency for car-to-car interactions for all cars.
New Damage Model
Fixed an issue where wheel damage forces were sometimes getting applied in the incorrect direction and angle.
Fixed an issue where removable car parts from other vehicles were showing up in Lone Practice Sessions.

– – – – ARCA Menards Chevrolet Impala
– – – – NASCAR Cup Series Class Cars
– – – – NASCAR Gander Outdoors Class Trucks

Road course tires will now be used by all vehicles when the vehicle does not have any other appropriate tire type to be used when loaded onto a Dirt Oval or Dirt Road track.
– – This fixes some loading errors that could be received because a selected car/track combination is not really intended to be run, but we no longer wish to deny our users this type of fun.

Rendering
A new Graphics Option has been added: Static Steering Wheel.
– – Previously, cars with displays built into the steering wheel were not removed from the world when the “Hide Steering Wheel” option was enabled. Now, all steering wheels regardless of type will be removed when this option is enabled.

The free-view camera has been updated so that Ctrl+Z is now a hotkey for bringing up the camera modifications window for the current camera as long as it is outside of a car.
Cameras now stay attached to their base platform instead of falling off the car when you take over control of them.
– – A new variable, “mouseAimRemainOnPlatform=1” has been added to the [CamTool] section of the “app.ini” file. Setting this value to 0 will restore the previous behavior where the camera would fall off the car when you take control.

A new setting, “DefaultChatReviewState=0” has been added to the [Replay] section of the app.ini file.
– – This setting may be manually adjusted to a value of 1 to request that the Replay/Session screen defaults to playing voice chat from the point of time being reviewed in the replay. This state can be manually toggled by clicking on the headset icon in the Replay controls area. The headset blinks red when voice chat is being played from the replay, and gray when still connected to a server and listening to live voice chat.

Hickory Motor Speedway
NEW TRACK!
– – A new asphalt oval, Hickory Motor Speedway, is now available!
– – – – Before NASCAR’s biggest names first shone under the bright lights of Charlotte Motor Speedway, many of them found their first successes elsewhere in North Carolina. The city of Hickory plays home to the World’s Most Famous Short Track, Hickory Motor Speedway, a .363-mile asphalt bullring that has welcomed racers and fans through its gates for more than 70 years. From its early days since opening in 1951 as a half-mile dirt oval to the current day, Hickory’s fastest drivers have had what it takes to win at racing’s highest levels. Ralph Earnhardt had five track championships in those early days, while Junior Johnson and Ned Jarrett also scored titles at Hickory early in their Hall of Fame careers. While the track would eventually be reconfigured multiple times before taking its current shape, the quality of names on track remained the same, with legends like Jack Ingram and Harry Gant earning titles of their own later on. For much of its history, Hickory played host to what is now known as the NASCAR Xfinity Series, and it even hosted nearly two decades of NASCAR Cup Series racing before the 1972 schedule shift that consolidated the division. Nowadays, it’s a premier circuit on the NASCAR Advance Auto Parts Weekly Series map, and a crucial part of multiple Super Late Model series’ calendars.

Hungaroring Circuit
NEW TRACK!
– – A new asphalt road course, Hungaroring Circuit, is now available!
– – – – Conceived in the mid-1980s, placed just outside of Budapest, and built in a rapid eight months, the Hungaroring became the host of the first-ever Formula 1 event in eastern Europe in 1986 when it welcomed the inaugural Hungarian Grand Prix. Originally, organizers had wanted a street circuit, similar to Monaco; while a permanent circuit became the eventual choice, the track features a number of tight and challenging corners that make it polarizing among drivers. In its more than 30-year history, the track has crowned two Driver’s World Champions and four Constructor’s World Champions at its events. It’s also the site of numerous firsts, including four first-time F1 winners and the first drivers from both Hungary and Poland to compete in the series. The Hungaroring has also added various sports car, touring car, motorcycle, and open wheel feeder series to its portfolio along the way, with a regular premier touring car event supplementing the schedule for more than a decade.
