Would it be possible to make the game able to export vehicles created into any format that would work on modifiable games that include cars e.g. GTA 4 (.wft) and GTA 5 (.yft). I know that would be hard but it would be cool and make it a lot easier to make vehicles for mods and lots of people would like it. when doing the exporting you could make it take out any parts that wouldn’t work in the games or you could make them be part of the main chassis group and have no collision so that the vehicle can drive without problem. Again this would be a great idea and i hope that you consider this at least. 
if you make a file converter, sure
