iRACING UI:

Practice

Fixed an issue where the drop-down menu for selecting a Setup for an Open Setup Practice was not rendering properly.

3D Model Viewer

Fixed an issue where if a car already had a custom spec .MIP file actively loaded onto it, it would not update when a new custom spec .MIP file or custom spec .TGA file was copied into the folder.

For a .TGA file to replace the .MIP, it must have a "last modified" time that is newer than the .MIP, or the .MIP needs to be removed first.

New Damage Model

Fixed the apparent root of the prevalent crash-to-desktop issues plaguing vehicles utilizing the New Damage Model.

This issue appears to have been caused by a corruption of the data when opponent wheels were being moderately to severely damaged, or when they were being reattached to a vehicle.

We are confident in the above fix. However, as a result of this fix, some sweeping updates have been made to our underlying tire attachment system. Because of this, we are taking the extra precaution of keeping the New Damage Model disabled on the following vehicles until we have had some proper time to re-balance their damage states. You can expect the New Damage Model to be re-enabled on these vehicles soon:

ARCA Menards Chevrolet Impala

NASCAR Chevrolet Monte Carlo - 1987

Fresh off of tonight’s Windy City 110, the Chicago Street Circuit is available now for purchase on iRacing! As stock car racing’s biggest stars wrap up 51 laps of action on FS1, get ready to hit some of the most famous streets in Chicago yourself on iRacing’s newest street course.

Have you ever wanted to know what NASCAR Cup Series racing would look like on city streets? NASCAR and iRacing partnered in the fall of 2020 to covertly shut down and scan some of the most familiar blocks of the city of Chicago to help bring that dream to life in the virtual world. You’ve seen it on FS1 as part of the eNASCAR iRacing Pro Invitational Series with the Next Gen cars—now’s your chance to drive it yourself!

At just over two miles, the Chicago Street Circuit incorporates parts of Michigan Avenue and Lake Shore Drive in a unique, nearly figure-eight layout. The picturesque city setting features Grant Park and the iconic Buckingham Fountain among the historic buildings and iconic skyscrapers in the background. Mixing full-throttle straightaways with heavy braking corners, Chicago manages to nail the essence of any great street circuit, while adding a flavor unlike any other.
