After dissapearing for a few days, I present to you:
Marussia! It finally exported to Blockland! Just, um, don't mind the fact that the car is hovering and the wheels are... um... yeah. I'll move to another topic soon.

Yeah this is the wrong place to ask, but, which way should the wheel be facing on export? X? -X? Y? -Y? Z? -Z?
EDIT: Okay, fixed the hovering issue (bounds were set up wrong on the wheel) and figured which way the wheels are pointed on export.
