As a 3D rendering guy I like speculating on this kind of stuff.
They could have re-used the sounds from the original video in the new one, and you can definitely export a piece of geometry that follows the track spline to translate the layout into another program. I know that NoLimits 2 can produce some pretty fantastic visuals, but I'm pretty sure that they're not as good out of the box as what's presented in that new video, especially with the big body of water, the terrain and all of the trees. Either they did the rendering and animation using some other program, or they baked the textures into a NoLimits 2 simulation (again, I lean far toward the former). Either way, I do agree that whoever did it did an incredible job.
I wonder, can Unreal Engine generate those kind of visuals?
It's definitely possible that they could have gotten the sounds from NL2 instead of sampling them from real life. Now that I've looked at it more I see that there is no possible way that NL2 could produce those kinds of visuals, as powerful of a program it is. The textures are very different and it overall doesn't feel or look the same. I also do some 3D modeling/rendering so I also like to speculate about this stuff
Anyway, the view on this coaster... how about that? Watch out MF, you have some serious competition under construction
