I've always wondered why the trees from Sergio's tracks were a little off. I wonder if it's an issue with "baking" vao ? I've had good results adding some external ambient occlusion with Reshade on those tracks, and hacking with ambient light distance in Pure.
A good portion of Sergio's tracks are having the same weird tree lighting, but it became more apparent since CSP 2.1, especially after 2.4. Since i'm AMD equipped i cannot bake the tracks for testing, but it might be worth a shot asking someone with a geforce to give it a try.
Anyway, missed your norising update, gonna test it now👍
