I was messing around with a Steel Phantom recreation and decided to have fun with it. I basically redid everything from the bottom of the second hill and on. Tell me if you think its worth releasing.
The main problem I see is in that area. Some of the tubes for the roll and the turn are too thin IMO. You're just a little scarce on the supports on the Heartline Roll thing. Also the turn at the bottom of the screen: I would lower that terrain a little and give it better supports. Only other thing I see is watch that shaping at the bottom of the Pretzel Loop; its a little weird looking.
Actually, I just got done fixing the terrain. And the heartline roll was the thing I was working on now. Perfect timing, eh? And the transition from the pretzel loop to the roll is almost perfect. Thanks for the pointers!
It was never meant to be a recreation. Also, I'll post it next week. I have more fixing than I thought and Pyro achievements for TF2 are out, so that's bound to slow this down.
EDIT: Small update, all pics with (2) next to them mean they are the newest ones. I tweaked the terrain more, changed some supports, and lowered the Gs down. I also added a small trim brake before the loop, but the pics were taken before I added it in.
