That is the release of the 'R33 Project' that we began quite a few years ago; development of this mod has been placed on pause since 2019, only to be restarted in the fourth quarter of 2023.
Since then, we have done considerable revision on 3D and physics; there are still some 3D/2D/animations tasks that need to be completed, but the fundamentals are in place.

Hard Requirement: Custom Shaders Patch (CSP) v0.2 or above. Physics were designed around CSP functions; without these, the car's physics would not operate properly, resulting in game failures.

IMPORTANT
If you have installed earlier versions of this mod (v0.1 to v0.2b), erase all relevant files from the AC/content/cars folder before installing v0.3.

Skyline R33 Models - Version 0.3:
