AHG Problem/Help

I am new to the AHG program and I am having a problem heartlining the first drop of my newest coaster. The drop is similar to Maverick's first drop; it's a little steeper than 90 degrees. When I try to heartline the drop going into the first element, the drop always ends up twisting downward like on Kingda Ka and Top Thrill Dragster. I thought it was because the steepest node is on the relative roll option, but I tried all I can think of to make the drop with no banking. What can I do to fix this problem?

get relative roll off, correct the banking, make the spine pure black and it should work...otherwise i dunno

I tried that and the track does not completely twist like Kingda Ka/Top Thrill Dragster anymore, but is still highly banked.

Make sure the track isn't banked at all when you put it through the process...Try making the two segments surrounding the steepest node 100% black...I don't know that's all I can think of...

You found one of the toughest problems with AHG... However, it's not impossible.
Do this:
First split the drop into small segments (3-5ft), especially around the points where it crosses 90?????????. Next bank everything WITHOUT relroll and switch OFF conroll. Finally enforce banking by colorcoding black and additionally enforce a very high filter on the segments that cross the 90????????? slope (red 255 should do(255,0,0) - if it doesn't, try green 10(0,10,0)).
Run through AHG.

When using the AHG, should you build the entire ride first, then send it through the AHG, or should you ahg each element as you build it?

Build the entire ride and then send it through the AHG. Of course, don't include lifts, stations brakes etc when using the AHG on it.
