Not to derail the topic, but personally I disagree with that last part. I loved KK's animation, 3DVIP did an amazing job with it. The physics are perfect, the music is exciting, and overall it was done really well. TTD's animation was done subpar in terms of animating technique. You can tell the guy used keyframes to make the train move, which makes it unrealistic. I had to do a lot of digging to find this, but Keith (3DVIP) developed his own program within 3ds Max in Maxcode that calculates the physics just like No Limits would and the result is real coaster physics. Instead of manually changing the speed for each portion of the track, which doesn't usually yield great results, he just places the train and the program calculates the rest with precision. Interestingly, after doing a ton of digging on old websites that no longer exist and recovering corrupted files, I found out that he actually submitted an animation for TTD which used real physics and was far superior and light years more realistic than the official one, but for some reason CP chose the other one over his. I prefer it to the official one.
Can you give a link to that animation.
