Note that Tossha hasn't validated these models yet so there can be errors in it. I do know of two errors which I can't fix though; the dirthills having wrong heights and the big scenery arches being placed in the wrong location.
The blocks that still don't have 3d models yet:
StadiumWater, StadiumPool and StadiumDirtBorder

Tip: Use the "Hide undisplayed" filter to reduce the lag
I do hope Tossha will soon come online again. Not only will he finalize these models but there is a whole new TrackStudio version with lots of cool features waiting to be released. For so long...I hope this version will do okay for you too
