Its hard to find formulas other than the mainstream fvd's and hsak. I am looking for any formulas for hills like a hyper and inversions. If you got anything else feel free to post it.
Do you have the other ones then Alton_? The eggFu ones are shown in the link below. Maybe he never released them? Could you please email me all the other ones you have. I cannot find them on my harddrive and need them for vertigo. My email is: coastercrazyjared@hotmail.com
Inversions are basically just 360????????? curves, so just make a 360????????? curve first. Then to vary the distance between the entrance and exit, use slope. Then to make it have that teardrop shape use the zerrz value, which moves the exit of the track along the z axis. Also you'll want to make sure your zerrs value is 0.
Then load it in the purg, and rotate it 90????????? so it is upright.
