So I made a new CT in SketchUp and all worked fine. I tried the course in Dolphin to see that the course loads up. And it worked. I tested the first 10 seconds(later I tested longer and still no freeze). The course was on luigi circuit. So now I started my wii and mkw and so on and then I started the track (on n64 bowsers castle) but after the countdown was finish the course freeze. Everytime, also when i put it on luigi circuit. But why does the CT work in Dolphin and not in MKW? Anyone have an idea?
p.s.: the track didn't freeze before I made the KMP (enemy, item routes, checkpoints...) I used the KMP from Volcanic Skyway, cuz of the many objects. The course_model is from Bowsers Castle.
