Next in line to receive its long overdue dose of TLC is none other than my ageing Aztec-themed invert, Humunga, and having been built in 2017 after a few other rides which have since been demolished, it's now the oldest remaining coaster in my park. After a period of time it became yet another coaster that I didn't pay much attention to, but over the years, I've slowly been adding more and more to it and doing some trackwork here and there...and as of more recent changes, it's turned into the masterpiece it was born to be. Below is a brief overview of the coaster, even if the picture isn't that great:
One of the earliest changes I made was the interaction with terrain and scenery surrounding the ride, as I really wanted to ensure Humunga was not only heavilly themed but also all-round an intense experience. Firstly, as my personal preference with real world inverted coasters is actually close interaction with terrain, I started here. Below is a pretty good example of guests seemingly on a collision course with an oncoming mountain!
To then further expand on the ride's already huge catalog of near misses, I very recently constructed a colossal stone archway behind the coaster's Immelmann element, which riders miss by inches. Despite this image making the arch look vertical, it's actually on a slight lean, so the base of the building lines up with the coaster itself and the top half is of course well clear of riders. It also therefore creates a nice illusion of the arch being vertical as mentioned above, as well as riders once again being sent on a collision course.
Following this, the Immelmann itself needed a bit of seeing to, as the inversion had always looked a bit lop-sided (smoothing was a classic rookie error in my early days of playing this game), so after a little fiddling around, I had it looking smoother and more realistic than it had been before.
Other bits of scenery have since been added to the queue outside the station building, such as the priority pass queue surrounding the main queue being bordered off by a themed wall, various adventure pieces such as character tiles and vines have been dotted around existing buildings...and the station building itself has received an awesome lighting effect on the steps, which makes for an epic view at night.
As part of the coaster's pre-lift section (obviously inspired off Thorpe Park's Nemesis Inferno), riders begin their adventure by dropping into a tunnel in the side of the mountain, underneath the base of the station. Originally, because the building would overhang here otherwise, I'd attempted to theme that part of the building to instead appear as if it was eroding away down the side of the mountain, however this proved hard and didn't look too great in the end. So recently I instead created a separate building consisting of identical wall and ceiling pieces so that now it lines up with the tunnel entrance and looks very neat overall.
The ride entrance needed some work too, so, in similar fashion to the stone archway mentioned earlier, a similar one was built behind the existing facade which had formed the entrance previously (the stone face, wings and ride logo). The facade was then recoloured appropriately to blend in with its new backdrop. New fire effects were also added here to dramatise the train passing through the vertical loop.
Finally, the station has also received some extra details, such as improved lighting, character tiles and vines. The lighting is quite a major improvement, as, having been shown how to change the colour of lights while they're still activated, I was able to incorporate it here to create quite the lights show.
An effect seen on a lot of inverted coasters today, just before the train dispatches, the main lights on the ceiling will fade away, as red, purple and green lights either side of the train (seen below in a currently deactivated state) fade in at the same time, giving a cool "spotlight" impression on the train (the treasure chest in the corner is also illuminated by a red light at this point). Vice versa then occurs once the train behind has stopped in the station.
Other changes include, but are not limited to, a new paintjob for the track (originally it was dark blue with dark brown supports, in oppose to its current teal and dark red scheme), new rockwork, waterfalls and the addition of high fences to cordon off pathways close to the ride.
But as I've learned the longer I've played this game...anything is possible.
