The circuit has good details. I tried to take some turns and I saw that when I get out of the circuit and hit a fence with tires, there are times when it goes through them or the car gets stuck. For the rest, good job.
Outstanding! The trees are VERY good looking in 1.3. Better than many official tracks.
Any chance you could make the poles/sticks in corners to have physics/collision? A bit immersion breaking when AI drives right through them in front of me. If they would fly in the air on collision (or AI wouldn't blast through them), this would be perfect
