Well, for the most part, the custom supports look good. However, there's a problem: some parts, apparently the TMT objects, don't show up so some of the supports (especially on the outside of the lift hill) are left dangling in air. And there are still no supports for the unsupported track over the station.
I don't fully understand the TMT part of this. I was already subscribed to this ride so the revised version with custom supports had automatically updated when you published it. When I went to place it, however, I got a message saying it needed TMT parts I didn't have and asked if I wanted to download them. I said "yes" so the game paused for a minute or so, and then the blueprint finally appeared on the end of the cursor. But I couldn't find any TMT items anywhere in it, and no new TMT items showed up in my parts lists. So there's something going haywire there.
To try to resolve this, I unsubscribed and resubscribed to the ride, then tried to place it again. This time, I did NOT get the message about missing TMT parts. However, there are still apparently some parts missing because again, some of the supports were left hanging in air.
A more serious problem, however, is that the ride cannot be used in its present form. It's impossible to connect a queue to the entrance gate. This is because the track over the station is both too low and comes too far out towards the edge of the station to make the path-placing system happy. You always get "obstructed" when trying to connect the path (it was VERY hard to even get the entrance gate placed).
This is one of the several very annoying things about the ❤︎❤︎❤︎❤︎ station platform when it comes making life-size replicas in PC. I'm afraid you'll have to deviate from reality a bit here and move the track over the station. I recommend tightening up the turn there a bit so the track doesn't come any closer to the platform edge then the actual station track. This would not only solve the queue problem, it would allow placing the exit at the departure end of the station where the exit path on the platform is, which would speed up the loading time.
