Why won't my wheeled vehicle move?

Hi all,

I facing same problem, and I already read all comments on this page, did everything that I can, but there is no way to make a single car to move on Unreal.

I already spent about 10 days trying to move a single custom car, but it’s impossible.

If I use mesh provided on tutorial, it works perfectly, but following same steps, I can’t make my car move. wheels are half in floor all time, doesn’t matter how many changes I make in Blender.

For me, this is not easy. I already spent 10 days without success. I know that for some of you this is something trivial, that is why I’m here.

Can someone tell me what is wrong with my model?

I’m sending blender file, as well exported fbx file. (PS: I’m just a baby with Blender, as well with Unreal)

Well, my file has 42MB, so I had to upload to a different site. file will be available for 7 days:

If someone can help, could you make a video or explain exactly which menus or keys your have pressed while working in Blender?

Thanks in advance.
