I just built this loop, spent alittle over an hour on it (had to rebuild half of it to change the angle). http://www.youtube.com/watch?v=YIjot2yyOiQ YouTube - loop2 As seen, it doesn't work for hogs.... YouTube - Rough Loop This is a few attempts at mostly failing.... I just threw some grav-lifts on there and it's already working a little less than half the time. (approx 4/10). That's not bad, considering my last mongoose loop took me around 5 hours and only worked about twice that good. I'm showing you guys this, looking for ideas, and seeing if anybody can or has made a better one yet (on Reach). I have seen just a ton on youtube, google search and various sites, and they all REALLY suck. Hopefully, if I got some spare time tomorrow, I'll be able to fiddle with this a bit and make it work better. If you'll notice, I started to put up side rails, to help guide it, like I did in my Halo3 loops, but it doesn't need them, so I don't think they'll stay. And another note, the largest barrier with making the loop for Halo3 was the fact that Master chief would fall out if he went upside-down. In Reach, that doesn't happen, so I think that's why I've had such early success on this. My old Halo3 loop-d-loop for comparison.. YouTube"]http://www.youtube.com/watch?v=crNYcumWcOw
It might be failing cause it looks a little bumpy. Try smoothing it out with fine editing (keeping left stick clicked in while moving object) and it will be smoother and will work better. I could see this in a cool race map of sorts.
Embed a shield door in the track about 30 degrees after the apex to help pull it through that part of the turn; there should be a point where it only exerts a slight force on the mongoose. If you want ideas, a video of the track not working would probably be better than one of it working.
The problem with that, is that it fails slightly differently. It is easier to make a mongoose loop on reach, but they made the camera angle really hardcore, and it turns your wheels WITH the camera angle. I have ideas to solve this, but it's going to take a bit. Thanks for your suggestions so far!! I've added another vid showing the lameness of hogs!
