iRacing 2021 Season 1 Release Notes Highlights and Commentary

December 8, 2020 by Jeff Kendrick Leave a Comment

iRacing Beta UI

3D Car Viewer

This new feature includes a 3D car viewer tab on some of the screens in the iRacing beta UI. When you click on the tab opens a new window where you can view a 3D model of the car that is rendered in real time, just as though you are viewing the vehicle in the simulator. You can rotate and zoom using click and drag and the mouse wheel.

You can view all liveries in the 3D car viewer including those custom liveries you have saved on your computer. Painters will not have to load the simulator to view their updates.
