Both. Thanks for bumping this thread.
I've had to remake the entire thing, which has been frustrating, and lack of motivation has made it take a very long time, but progress is being made.
Plus, thanks to this being the second time I've made it, it's turning out even better than before.
It's been over a month? Yuck.
Things to do:
Interior: Dash, seats, steering wheel, seating and shelves in back of ambulance
Ambulance-specific doors
Decals/paint
Properly-animated lights (instead of scheduled hidenode/unhidenode which make it a lag meter; if I learn how to do this I'll probably update the CVPI)
Acquire ambulance sirens
After release:
2006 E-Series van with non-ambulance rear end (including cargo and passenger variants, garage support)
