I've been working on a project lately. It's a stand-up coaster called Sphinx. I've just got the basic trackwork done and some terreforming to get a general idea of how I'd want it to be. I plan on adding some 3ds (anyone out there want to help with that?) and still have some smoothing/heartlining issues to work out. This coaster features 8 inversions and speeds up to 70 mph. It Dives in and out of the ground frequently and I need some tips on avoiding the ground hits. I've put fog around them but you can still see the hits..grr. But here's some pics.
