I'm having an issue. I converted a free vehicle model, scaled it for GTA, broke it into proper components, and attached the appropriate dummies. However, when I try to spawn it in-game it never appears. The game doesn't crash, but the vehicle will not appear. I've tried setting the whole object to a GTA black color Material and try it IG, but still no luck so I don't believe it's a .txd issue.
It appears that after exporting and re-importing the .dff, it tells me it's a non-standard DFF and only imports the wheel... Makes no sense considering I did this in 3ds Max and it's never been in Zmod. And yes, I selected ALL of the vehicle when exporting.
